Re: [RE-wrenches] Enphase Max Distance
HI Rick, The distance that our power line communications (PLC) signals travel will be impacted by the electrical noise on the site and the impedance of the wiring. I don't think we have published a max distance in any of our recent tech briefs or planning guides. That said, in some of our commercial design guides we had previously recommended up to 250 ft in a non-filtered environment and up to 600 ft when the IQ Gateway and microinverters are located on the load side of a power line filter or an isolation transformer (for example, on a dedicated 480V primary to 120/208V secondary transformer). Keep in mind that when the PLC signals are used for controlling the microinverters, such as sites that have power export limiting (PEL) profiles or when the microinverters are paired with IQ Storage systems, the communications must be more reliable than when used for monitoring alone.

Re: [RE-wrenches] Enphase IQ7 versus IQ8
That is correct, Jay. You only need the rapid shutdown switch if you have IQ 8s and an IQ System Controller. One of the big advantages of the IQ 8 over IQ 7 when paired with storage is that the 1.5 PV to storage ratio does not apply, so you can install larger PV systems with smaller battery systems.

If there are Enphase batteries involved, wouldn't the IQ7 do the same job on the roof? In a straight grid tied scenario, again the IQ7 would do the exact same thing. You would not have an upgrade path to solar only backup, of course. I'm just having a hard time understanding the value proposition of the IQ8 in most of the situations I encounter. They cost significantly more, and you need an additional rapid shutdown switch when using batteries that can be quite a pain in some scenarios. Am I missing something about the switching speed, energy harvest capability, or the way they interact with batteries that makes them better? P.S. I am aware of the very small power output differences by model number and I am referring exclusively to 240 volt applications. I understand the 208 volt advantages of the IQ8.

I would say it’s likely okay, but to speak in the vernacular, “watch out sucka”. Vmp will be lower due to temperature coefficient, dirt on the panels and degradation over time. But, the inverter likely wakes up above the minimum Vmp as Voc has the voltage but the inverter can track below minimum Vmp after it wakes up and starts tracking. How far below official Vmp can it track? 18-58 is the tracking range.

Hello Wrenches, We received IQ7 inverters from Enphase as RMA replacements for failed legacy (M175 and M190) inverters. I understand the IQ7 PLC is line to line, and the legacy INV PLC is line to neutral. Have any of you successfully gotten a circuit with a mixture of IQ7 and legacy INV to communicate? This is a large project and shuffling old INV in order to make separate circuits with only IQ7 and only legacy INV will be difficult and expensive. It appears that Enphase is telling us we need to do that (is that correct Nick S.?) but I am trying to see if any of you have successfully mixed on the same circuit, and anything you may have had to do to make the communication work. There are some older threads about installing ferrite loops to reduce noise, but I haven't found anything specifically about mixed circuits.

Re: [RE-wrenches] grundfos cu200 failure?
Hi Jay, Is it a long wire length? I had a similar issue with a Aquavar Solo2 pump controller recently where the float switch was not turning the pump off. The wire length from the float switch to the pump controller was over 300ft and ran underneath an electric line. I believe that a small (2V) was being induced into the control wiring and that 2V signal appeard as a closed circuit to the pump controller. I used the float switch to control an external contactor. The external contactor switched a short length of wire on the pump controller's dry contactor and that resolved the issue.

Re: [RE-wrenches] Incompatible Module with Enphase Microinverters
Hi Jason, There is a risk of damaging the microinverter if the input voltage goes over the "Max Input Voltage" as listed on the datasheet<https://support.enphase.com/s/article/Enphase-IQ-7-and-IQ-7plus-Microinverter-Data-Sheet>. The max input voltage is 48Vdc for the IQ 7s and 60Vdc for the IQ 7+ microinverters. You can reference the Enphase Module Compatibility Calculator<https://www4.enphase.com/en-in/support-module-compatibility-en> and see if that specific module is compatible in that specific location. The largest risk of seeing a high voltage at the input terminal will occur on a cold day when the electricity is out or breaker is off. If the utility power is present and in range, then the microinverter will likely be powered up and will pull the DC module voltage down to the Vmp.

I have "inherited" a site where my initial research appears to indicate they have 300W 72-cell modules on IQ7 microinverters. I might have bad information from what the original installer entered in Enlighten - that remains to be seen. While they have a branch circuit down, the other branch circuit seems to be working completely normally. So I'm thinking they actually have 60-cell panels installed, but I am still curious what would happen if they were, in fact, 72-cell.

Re: [RE-wrenches] Strange noises from the roof
I had a similar experience 13 years ago on a house that had an addition built onto it. The array spanned between the original home and the addition, and the structure would creak in the evening as the aluminum racking and modules cooled. The creaking was a result of weaknesses in the structure, but I fixed the issue by splitting the array where the two structures met. It wasn't a very easy fix, but it did resolve the issue.

Re: [RE-wrenches] Enphase noise interference to reporting; use ferrites
Thanks Jason and Scott, Jason is correct. The IQ system uses line to line PLC, whereas the M-Series microinverter communications were line to neutral. Most of the noisy loads (like magnetic ballasts, touch lamps, etc) are 120V line to neutral loads. For that reason, we see very few communication issues with the IQ microinverters. Also, the widespread adoption of combiner boxes has had a huge effect on improving communications. @scot.a...@solarcentex.com<mailto:scot.a...@solarcentex.com>, can you confirm that this site is using a combiner box. Keeping the microinverter and Envoy circuits separate from the other house loads is critical to ensuring good communications. We also have a power line filter product (Q-LCF-064-1P) that can be installed between the combiner and the main panel in the rare instances there are poor comms. That filter is very robust and has been designed to filter noise and signals in the 110kHz IQ microinverter communication frequency.

True, but this is MUCH less of a problem with IQ compared to M-Series. I just installed 212 IQ micros on a building with 268 existing M-Series. The M-series required ferrite rings and the IQ worked flawlessly without any filtering (although it took about 3 hours for all of the IQ micros to initially come alive initially). This is a grocery with a lot of noise / motor loads.

Re: [RE-wrenches] Old & new Enphase communication issues
Hi Wayne, Jerry, and Wrenches,
The statements made about IQ not being compatible with legacy Envoy-S systems
is mostly true, but that does not apply to the microinverters listed on the
Enphase store. The M215 and M250 micro kits that are listed on the Enphase
store include a communications adapter cable that changes the PLC signals from
L-L to L-N. There are also modifications to the inverter to allow it to talk
at the same frequency (144kHz) as the Envoy-S.
The adapter cable also allows the microinverter to plug into the legacy Engage
cables and talk to the legacy Envoy-S. We sell 40 drop lengths of the portrait
Engage cable (ET10-240) as well as Engage Terminators, Engage Seals, Engage
wire clips, and Engage Accessory Kits (which include the Disconnect Tools)
These are legacy components are available at an online store here:
https://store.enphase.com/storefront/
Note: the M215 and M250 microinverters do not have the ability to perform
advanced grid functions (AGF) functions.
These micros can be used for small expansion systems, but for larger expansions
it makes sense to just install an IQ Envoy (second Envoy) at the site. You can
have two Envoys and put them on a single Enlighten "System".
Be thoughtful about how you configure the consumption CTs when you have two
Envoys. If you have two Envoys, the production from the two Production CTs
(and Consumption CTs) will be added in the cloud and will display correctly.
You need to be careful though if the production from one system is on the load
side of the other systems consumption CTs. That production will throw off the
consumption readings. You can fix that by installing a second set of parallel
connected consumption CTs backwards on the production circuit to subtract that
production from the consumption CT readings
Cordially,

The new inverters communicate at a different frequency then the older units,
you will need a new EMU to connect to the new inverters, as so many of the
older units have failed it might be best to upgrade all the inverters at the
same time if they are compatible with your older modules

Re: [RE-wrenches] Enphase Envoy in PVC J-Box
Hi Jason, In the IQ Planning Guide, the reference to calculating the OCPD at 1.25 x the inverter continuous output current rating was in reference to sizing larger OCPDs for the Enphase Q Aggregators (branch aggregators.) I did not intend to imply that smaller circuits should be installed on breakers smaller than 20A. 20A breakers are sufficient for protecting a single branch circuit of IQ Microinverters, provided that the field wiring is sufficiently sized.

Somewhat unrelated is the confusion about AC branch circuit OCPD in an Enphase IQ system. My understanding was that each branch circuit could be protected by a 20A breaker, but I always designed it for minimum branch circuit OCPD at 1.25 x combined inverter output circuit rating. The Original IQ Combiner had 20A breakers preinstalled, so that was not an option. The IQ design guide states that for the Combiner+ and Combiner 3 that the installer should select breakers with the correct amp rating. The M series design guide stated that 1.25 x combined inverter output circuit rating should be used. But it seems that Enphase would approve of 20A circuit protection regardless of how the string is populated (up to the max). Back to the original thread - I'm thinking that a grounding conductor should run with the circuit conductors and just terminate on a lug or ground bar even if it's all PVC. As for whether the DIN rail needs to be bonded - no idea on that one... I could argue that it is not exposed if it is behind the Envoy I suppose.

Re: [RE-wrenches] Enphase question
Hi wrenches, The older generation micros (M190s, M210s, M215s, M250s, S280s) all communicated at 144kHz, line to neutral and communicated with the old EMUs, the oval Envoys, and the Envoy-S system monitors. The new IQ micros (IQ 6, IQ 6+, IQ 7, IQ 7+, and IQ 7X) no longer have a neutral, so we had to go to a new communication protocol which is 110kHz, line to line. You would need a new IQ Envoy for pairing with the new IQ micros in addition to the existing system monitor. If your customer wants to stick with HIT modules similar to the Sanyo's they had originally, then you can pair the Panasonic HIT modules with our IQ 7X micros.

Re: [RE-wrenches] Battery Backup for Older Enphase Systems
Hi Wrenches, We now have the ability to provide frequency based power curtailment. If you are AC Coupling with a battery-based inverter that can fluctuate frequency to regulate charge on the battery, then we can ramp our output up and down to regulate the charge more evenly. If you have an AC Coupled system using Enphase microinverters, reach out to me and I will set your company up with a grid profile that can provide this option. Once your company has been granted access to this profile, you can update the profile using either our Installer Toolkit (ITK) app or Enlighten.

Re: [RE-wrenches] Enphase and Smart? phone
To clarify Jason's point, there is a way to connect the Envoy to a WiFi network without using the Installer Toolkit app. You can hold the top button down for 3 or 4 seconds, which will put the Envoy into WPS mode. If the home's router also has a WPS button, you can also hold that button down for a couple seconds to start WPS mode on the router. If the two buttons are pushed within a couple minutes of each other, then a WiFi connection will be established without having to enter the WiFi password manually. One advantage of WPS is that the Envoy will maintain a connection to the router even if the WiFi password is later changed.

This is how we always used to do it. You would need to establish an Internet connection using an Ethernet cable or an Ethernet bridge. I don't think you can connect the Envoy to Wi-Fi without the Installer Toolkit. On the old Envoy's we used USB sticks for Wi-Fi, but the new ones have built-in Wi-Fi. So in short, the Installer Toolkit is light years better, but it isn't 100% necessary. If you want Wi-Fi you need the Installer Toolkit.

Re: [RE-wrenches] Battery Transport
I've gone through the hazardous materials transportation training this year and have received a certification for transporting our LFP based AC Batteries. Title 49 Code of Federal Regulations (CFR-49) applies to the transport of Lithium-Ion batteries by road and highway shippers and IATA regulations apply to shipments by air. My understanding is that generally speaking, a company that is delivering batteries as part of their regular business do not need any specific certification, but should be trained on safe transportation procedures. If you are a driver that is delivering the batteries for a shipping company, then you must be more familiar with the labeling and packaging requirements and training is required. CFR-49, Part 172, Subpart H states that if you are a Hazmat employee, you should be trained to properly transport hazardous materials. The employer is ultimately responsible for verifying that the employee is capable of safely transporting these materials, but no specific certification is required.

Re: [RE-wrenches] After market SMA TL inverter shade covers
Hi Wrenches. Yes, our product is NEMA 6, so is pretty robust once the DC and AC cables are connected. That said, our M215 Installation and Operation Manual states that the microinverters should not be installed in a location that allows for "long term exposure to direct sunlight." The challenge with north facing locations is that the sun does pass to the north of direct overhead for several hours a day in the summer months. Depending on the amount of exposure during the summer afternoons, this could be problematic.

Re: [RE-wrenches] Pass through/transition box for Enphase
Hi Wrenches, Enphase was manufacturing Engage Cable with fine strand (Type K) wiring. Due to the challenges with wire terminals that are being discussed, we switched our manufacturing lines to standard, 19 strand conductors. The transition to 19 strand Engage Cable occurred in late 2015, and the stock of fine strand cable should be largely flushed out of distribution channels at this time. Our manufacturing and distribution channels are set up to so that the product that comes in first goes out first, so hopefully you don't have to deal with this issue again.

I bet that a huge percentage of the installs out there are not meeting the listing for fine stranded conductors. That said, we use ferrules on the individual fine stranded conductors and then make the splices with the Ideal/Buchanan splice caps. This particular combo was presented in the SunPower ACPV instruction document and says it is listed for their class K conductors. I haven’t looked up the listing documents myself (at least recently) since this was presented in the manufacturer’s manual. As I posted before, the Ideal splice caps are the bomb! We love them and I’d highly recommend checking them out if you haven’t already.

It does not list it for use with anything other than standard stranded conductors. If it is not part of the listing, it is not approved for that use, regardless of historical or anecdotal use. That is what the NEC says, and what the UL listing says and the UL specification for their listing says.

The problem with these types of connectors is that the set screw that you turn to tighten the connection is in direct contact with the wire strands. As you tighten it, it rubs the strands in a circular motion, which will stretch, flatten, and tear the strands. It would work fine if you use ferrules, but not without them. Terminals that are rated for direct use with fine-stranded wire would have a clamping-type terminal, where the screw used to tighten the connection pushes down on a solid piece of metal which then clamps the wire. Even in this case, it may still not be approved for fine-stranded wire depending on its design. The Buchanan splices should be fine. They are basically the same as a ferrule, except that they are crimped with a crimping tool instead of the pressure from tightening a screw in a bus bar. The crimping tool is not in direct contact with the wire strands, so there is no tearing or other damage to the wire. However, the spec sheet does not specify the acceptable wire types, and I can’t seem to find anything with a Google search. It might be worth contacting Buchanan/Ideal to see if they have better info.

Re: [RE-wrenches] Pg meter reading
HI Jay, I would believe what the PG agent said. When the utility began to use the GE Smart Meters (with SilverSprings zigbee card) a lot of new "features" were rolled out in California. The smart meters can detect if there is selling of power prior to an authorization to interconnect. If they see power flowing backwards, they charge it as consumption! The smart meters also notify the utility if a system is backfeeding the meter without being authorized. It makes sense that they would also cap the amount of sell back at or near the inverter kw. That is really sad, if it is true, but not surprising.

Re: [RE-wrenches] meggering module-level electronics
Hi Kirk, There is little to no need to megger test Enphase cabling, and we would not recommend it as part of the normal installation process. Since the microinverters are connected to the cabling in parallel, a microinverter or module failure will not impact the other microinverters/modules on the branch circuit, so it is pretty easy to find where a problem has occurred. If a fault occurs on the DC wiring of the microinverter/module pair, then only that one microinverter will be affected. If you want to perform an insulation resistance test on an Enphase array, you must ensure that the microinverters are unplugged from the Engage cabling. The surge suppression hardware within the Enphase microinverters will provide a false positive reading if you try to megger test the cabling with the microinverters attached to the cabling.

Re: [RE-wrenches] AC Coupled + CC Grid Feed Input
Hi Drake, I'm happy to discuss the ins-and-outs of this with you by phone. My cell phone is listed below. I have installed AC Coupled systems using Outback GVFX inverters and a 120-240 transformer. My experience is that this works fine. We have published a basic document on this, which is primarily focused on the major pitfalls; - Protect the batteries from overcharging - Don't exceed the pass through limit of the GVFX inverter - Don't allow the Enphase microinverters to connect directly to the output of a generator With the Outback GVFX inverters, I would recommend using the auxiliary relay of the Outback inverter to shut-off the microinverters with a relay when the batteries are charged. The tech brief on AC Coupling is available under the tab for Tech Briefs at; http://enphase.com/global/resources/geo_us/ On Wed, May 28, 2014 at 2:47 PM, Drake drake.chamber...@redwoodalliance.org wrote: Hello Wrenches, We put a system in a year ago with an Outback GVFX 3524 with 2205 W of PV and a Midnite Solar Classic CC. The system owner would now like to expand the system by another 6 modules. Our tentative plan is to AC couple 6 Enphase M-215s powered by 6 REC 255 W modules to the Outback. This way, the GVFX 3524 would be selling power on its own while simultaneously feeding power back into the grid through its transfer switch. The plan is to drop the voltage to 120 V using an autotransformer before feeding the power into the protected loads panel for AC coupling. Has anyone tried this configuration? Can anyone see any problems?

Re: [RE-wrenches] 2014 NEC
Hi Jay, It is not acceptable to wire the AFCI breaker with the utility power on the output of the AFCI breaker. That does not meet the specifications for the AFCI breakers. These breakers are sensitive to having voltage on their output when the breaker is opened, which can damage the AFCI breakers. Currently, there are no AFCI circuit breakers that are listed for back-feed. On Tue, May 20, 2014 at 8:10 AM, jay peltz j...@asis.com wrote: HI Will, You can do this.

Re: [RE-wrenches] Solar World shattered module
Hi David, I've seen this a lot of times, and it was always caused by the diode failing, which caused the diode to get very hot and would result in the glass shattering. This was often obvious because the area around the diode would become black and the module j-box would sometimes begin to melt. One time I was replacing one of these modules and burned my finger on the glass near the diode. On Mon, Apr 21, 2014 at 3:32 PM, Dave Palumbo d...@independentpowerllc.comwrote: Wrenches, I have a customer with one SW 230 poly V2.0 frame (top mount) module that has shattered glass. It is on a DPW TPM10 pole mount. She noticed it the other day and does not think that it was hit by anything. I agree that is unlikely based on the site conditions. Other than by a falling tree, thrown rock, or twisted frame – is there another way that glass shatters on a 65 degree tilted pole mount like this? We installed the system 2 years ago. The module was on the lower corner of the array. · Is it likely that this modules frame was being pressured by the module(s) above it? TPM has two rows of 5 modules in landscape, so this bottom module has 4 modules mounted above it. Again it is a top mounted DPW pole array. · Or, is there another way that glass shatters on this type of module? I have not visited the site yet, just received the phone call today.

Re: [RE-wrenches] Microinverters with S-5-PV
Hi Jason, Using the S-5 mini clamps does work with our microinverters, but you do want to keep the microinverters off the roof. Enphase recommends (in our manual) a 3/4 distance off the roof. The microinverter can cause the seems to bend over, and inspectors may take issue if the microinverters get too close to the roof. If you use a taller S5 clamp, then the microinverter can run downhill, parallel to the seems. In that case, the microinverter will sit on the seem, which we support 100%. Another issue is wire management, which you brought up already. Clipping the cable to the module frames is a good practice. An additional fender washer is not required below the microinverter. On Tue, Nov 26, 2013 at 9:12 AM, Jason Szumlanski ja...@fafcosolar.comwrote: Does anyone see a problem (NEC/UL/physical) with mounting microinverters to S-5 Mini clamps and mounting PV on S-5-PV Kits? The trunk cable could be supported with clips on the module frames. Wire management could become a bit difficult, but doable. This would be a pretty cost effective mounting method compared to rail mounting, I think. The micro would not have much of a base to sit upon, but maybe a fender washer between the clamp and the microinverter would be fine. Has anyone done this?

You will need to be sure that you convert the 0.154 to 154mV. On Mon, Sep 30, 2013 at 12:24 PM, William Miller will...@millersolar.comwrote: Nick: ** ** What is the upper voltage limit for the M250?

Re: [RE-wrenches] GEC sizing for a high amp, low voltage PV system with microinverters
-), then your PV system is considered to be grounded. If the system is grounded, the combined DC-GEC and AC-EGC sizing requirements in NEC 690.47(C)(3) apply. The larger of the EGC (Table 250.122) and GEC [250.166(B)] sizes will be required. More specifics on the PV module Vmpp and micro-inverter you're dealing with would be helpful. Regards, Gary Willett Icarus Solar On 9/17/13 8:37 PM, Aladdin Solar wrote: We will be installing a 40KW grid-tied PV system that uses PV modules wired in parallel as per the module manufacturer -- so it's a high amperage, low voltage system on the DC side. 2 branches of about 3KW of parallel wired modules each come together onto a DC bus. The DC branch conductors are sized as 2AWG. The inverter system provided by the manufacturer consists of a number of UL1741 single phase microinverters that all are powered off of the low voltage DC bus. So there's a bunch of microinverters in parallel, combined output is single phase power. Those microinverters have a ground lug labeled GEC. You know where this is going... Assuming we are following NEC 690.47(C)(3), we'll be treating this ground as GEC and following all the GEC rules. My understanding is that because the DC conductors within the array are 2AWG (NEC 250.166(B), we will need to connect all 12 branches and 6 DC buses with continuous 2AWG and bring it all the way back 300' to where the AC GEC bond is located. We're getting a lot of pushback from the electrical sub and even some disagreement from the module manufacturer on this--no one's ever seen a grounding conductor of this size being required for this application. Please don't get too bogged down with understanding the low voltage, parallel module spec and the massive number of microinverters involved. What I'm looking for is confirmation that I am properly understanding how the NEC GEC requirements apply, especially to the GEC size.

Re: [RE-wrenches] Envoy on ATT Hotspot
Hi Drake, We generally don't recommend connecting through a cell modem because they aren't very reliable and some data charges may occur on large systems. How many microinverters are reporting to the Envoy? Sometimes, the cell modem will disconnect any device that has been connected to it for more than 4 hours, which requires re-setting the modem. You may be able to configure it in a way to prevent that. If you do need to connect the Envoy to a USB device, then a Cradle Point MBR-900 would be a good router to use.

Hi William, You can use the Sharp 235s with M190s. The M190s will work with all 60 cell and 72 cell products. On Tue, Apr 16, 2013 at 4:54 PM, William Miller will...@millersolar.comwrote: Colleagues: I had occasion today to use the Enphase on-line compatibility calculator. My client bought some modules and M190 inverters from an E-bay vendor. The exact module model number was not listed on the compatibility list so I was recommended by Enphase to use the calculator. The result showed the module was compatible only with the M215 inverter. Further research revealed that the calculator will never indicate compatibility with M190s even if your module is indeed compatible. The reason I was given for this is that since Enphase no longer makes M190s the calculator would not recommend them. This is silly since we still encounter M190s in the field. Be aware of this situation if you ever need to use the calculator. I informed the customer support person of this concern and recommended that this tool be corrected to show all compatibilities. I don't know if they will change this, but I hope so. By the way does anyone know if the Sharp NU-US235F9 BX modules will work with the Enphase M190?

Re: [RE-wrenches] P1 micro performance
the inverter's wattage rating. So, can you over-do it? Sure. But there IS an overall kilowatt-hours-produced benefit for *modest* over-sizing the PV. What I *can't* answer is the long-term effect this may have on the overall life of the inverter. THAT depends on various intricate design considerations that went into creating the inverter in the first place. This isn't an Enphase issue, nor are they trying to mislead you on this topic. It's an industry-wide issue. Wrenches face it every time you designed a string system, especially those being installed in regions with wide temperature swings. Trying to explain in depth the how and why slightly larger PV is of benefit to a customer is like trying to explain photovoltaic equipment to the general public. As a competitor to Enphase .. I'm not coming to their defense. However, what Nick said (below) IS fact. Whether you elect to believe this or not is up to you.

Here it’s only March and clipping is already taking place. Imagine what kind of clipping is going to take place at higher irradiance levels later in the year. Yes, the monitoring program cannot as of now quantify what kind of harvesting losses would take place over time compared to an identical array using Enphase micros. But the principle remains unchallengeable: not allowing for maximum kWh harvesting is plain and simple NOT the best design strategy. “Some clipping is good”? You’ve got to be joking. Not being able to harvest usable solar energy is good? What kind of optimal design philosophy is that? As module outputs have been going up, Enphase has a vested interest in continuing to move product with little regard for the harvestable energy being essentially lost. Using larger micros that reduce or eliminate that clipping is prima facie a good thing if one cares about maximizing kWh harvest. As more micro products come on the product with higher outputs than the venerable and solid M215, Enphase risks being left behind and losing market share.

This is actually prime clipping season in many places (not sure about Hawaii) due to the cool weather. While there are more sun-hours in the summer, the cell temperatures are often high enough that you won't tend to see rated power out of the modules. While I'm not running performance models for work, the people who do are routinely increasing dc-to-ac ratios, often as high as 1.4-to-1. Having said that, most inverters aren't installed on a roof. (Not yet anyway.) I'd probably lean to a more conservative sizing ratio for micros. While I can imagine some scenarios where I'd be comfortable with a 215 W micro on a 265 W module—like a flat roof install in Vermont, which reportedly doesn't see 1,000 W/m^2 very often—I wouldn't try that here in Texas.

Re: [RE-wrenches] Clipping
Hi Jesse and Wrenches, One thing that should be understood about the production readings from a DC optimizer system is that the module level readings are in DC. That is the production before being converted to AC, and does not account for the losses of the inverter. It isn't really an apples to apples comparison to equate that production reading to the 225watt max output of the Enphase M215.

Re: [RE-wrenches] high insolation value and inverter undersizing
with comparatively lower output inverters. In effect, matching, say. a 260-watt module with a micro inverter with a max output of 225 watts reduces that 260-watt mod to 225 watts. It’s not a matter of if clipping will take place, but how much and how much actual harvestable energy will be lost. Out here in the tropics, even in January with the lower sun angle, we see irradiance levels well above 1,000 watts/square meter range. Take a look at what I copied today from a weather station that we installed at nearby installation. Given the clipping issue inherent in using undersized inverters, it seems to me that moving to larger output micros makes a whole lotta sense. I’ve got one of the first installs using the Power-One 250-watt and 300-watt micros and am so far quite impressed. Why use a 225-watt rated micro with a 225-watt or higher output mod when larger micros are now readily available? What are the views out there regarding this clipping issue?

Re: [RE-wrenches] Barcode Scanners
Hello Wrenches, Enphase has developed an Iphone/Itouch app that allows you to scan the Enphase microinverter serial numbers and sync them directly to your system in Enlighten, our web based monitoring system. We call it the Array Gun. The Array Gun is a system that consists of a compatible Apple device, the Socket Mobile Scanner CHS7Xi, and the app which is downloadable for free from the Apple App Store. You can learn more about the Array Gun at http://enphase.com/products/arraygun/. If you order the bar code scanner by December 31st 2012, you can get 25% off of the price with a coupon provided by Enphase at http://enphase.com/arraygun-coupon-code/. The Array Gun is an essential tool for developing commercial scale projects using Enphase microinverters. I used the Array Gun this month for activating a 400kW project, and know that it has also been used for activating a 1.6MW project and a 900kW project! They are handy for residential projects, too. One of our largest installers bought 30 of them for their projects. Keep in mind that if you are going to use the Array Gun, you will need to have your Envoy available to scan. Another critical note is to not make any changes with the Array Builder in Enlighten until all of the microinverter serial numbers are uploaded for that system. As you architect your large commercial Enphase projects, keep in mind that we are now supporting up to 600 microinverters (129kW AC) on a single Envoy system monitor, and a single System in Enlighten can be built with up to 1000 microinverters. Our applications engineering team provides free design reviews and design support on your commercial projects. We'll look forward to hearing from you. I hope this all helps.

Re: [RE-wrenches] Enphase M210-84-208-S12 Inverters Available?
HI Dave, You are correct. The Enphase Microinverters bond the DC positive to ground. This is not an issue. Most modules will operate normally with either; no ground bond, the DC negative bonded, or the DC positive bonded. SunPower modules are the exception, with a requirement for being positively grounded.

Don't most PV modules have negative grounds? Is this a problem for Enphase? A: Enphase made the decision to positively ground its microinverters to minimize corrosion. Because Enphase Microinverters are positively grounded, they are compatible with both positively and negatively grounded modules.

Re: [RE-wrenches] Enphase/Conergy Suntop and Weeb
Hi Benn, I manage the content on Enphase's Racking Compatibility List and WEEB List, and have worked with the engineers from Wiley (now Burndy.) We have tested the Enphase microinverters with multiple configurations of WEEBs and racking types, and the ground is adequate with 3 of the 4 tabs making contact between the microinverter and rail. The Conergy SunTop / CMC / M215 is not the only pairing where this occurs; it occurs with most pairings. Don't worry about this one. It is fine. No additional steps should be taken during the installation process to try and prevent this. What is more important is using a 1-1/2 fender washer to spread out the clamping force applied to the lid of the M215 microinverters. Feel free to reach out to me directly if you have any questions or concerns (my contact info is below.)

It seems to me that the inverter needs to be installed on the opposite side of the rail that the roof attachment mounting quickstone slot is located. This is a pretty important piece of info to know BEFORE mounting the rails and then installing the engage cable, before you figure this detail out the hard way. I don't see this detail mentioned in the Suntop, Enphase or Weeb install manuals, however in a related note I did come across this Important Notes http://www.we-llc.com/WEEB_problems.html about incompatibility with weebs and some modules.

As per the 2011 NEC, MC (metal clad cable) is now allowed to be run inside the building envelope for solar output circuits.

First, there needs to be a DC disconnect just before or just after penetrating the building shell. Most AHJ allowed us to place this disconnect in the attic within reach of the access door. Once we needed to place the DC disconnect on the roof and we were able to get away with a fused combiner box. Another time we actually needed to put a 600V 3-pole fused disco on the roof. Second, and this is really an obscure point. Only conduit, raceways and the like (not cable runs) were allowed in the attic space and walls. So FMC is okay but MC is not. It is an issue of unfortunate terminology. Third, you need to label the conduit “Caution – Solar Circuit”, even in the walls. Finally, where the conduit passes thru studs, you need protection plates on the studs to prevent screws or nails piercing the conduit. That’s my story and I’m sticking to it. -Peter Peter T.

Re: [RE-wrenches] NABCEP Test
Hello Ezra, Bob-o, and wrenches: I guess if I were to pass the exam, and if I could find my results, I would be content. However, I do have a concern that if the test is calibrated to achieve a 50% pass rate, that the problems must be made vague and confusing to cause difficulty. Here are my primary concerns. - The test material did not match the study guide - The most recent test seems to test us on a number of obscure OSHA facts, that do not really pertain to designing and installing solar, to keep the test difficult. - With each test cycle, the candidates are told they need to study x number of hours to pass the test, but only 50% pass, so the next group has to study 2x times to pass the exam. As more folks study harder and harder to pass the test, the test only gets harder or the pass level is raised to keep the same level of a 50% pass rate. Over time we have to study more and more obscure facts, that have less to do with solar installing and designing, and more to do with short-term memorization of unimportant material. Additionally, I believe that the test contained some mistakes. One question required an analysis of two roof surfaces, and we had to find which surface would produce more power, and how much more power. However, the azimuths were listed as 'Compass' degree readings, but the provided chart gave outputs for 'True' degrees. The question did not provide the magnetic declination for the site!

Larry, NABCEP provides test takers with a passing score and a partial breakdown of their score by exam blueprint area. It is always a bit confusing because we report only on those exam blueprint areas where there are sufficient number of questions for the information provided to be relevant. For example informing a candidate that they scored 50% in an area where there were only two questions provided little useful information but informing the same candidate that they scored 50% on an area where there are ten questions clearly informs them that this is an area where further study is required. We do not provide candidates with individual questions they missed as this would have a strong negative impact on the security of the exam. If we informed candidates on individual questions we would have to retire each exam question we did so with which would put a huge burden of developing new questions on our volunteer exam committee. It would also but a burden on the exam itself as we would be continually retiring statically field proven questions. I know it is disappointing to candidates to not see the questions they missed, and if I was a candidate I'd likely be frustrated as well. I also know that it is simply not practical to do so and that our procedures are in accordance to established and recognized testing protocols. Sincerely, Ezra Auerbach Executive Director eauerb...@nabcep.org To which I also add to replay to your last post: You are incorrect that 70 is always the passing grade. It can be a little lower or even a little higher depending on the difficulty of that particular test and if we have identified any questions which have proved to be unclear or ambiguous. It takes time for our testing agency to compile that data. It takes time for our test committee to re-evaluate the questions and how they were answered. Lastly, each and every Certificant (not Entry Level) testing results comes before the Board with the raw information and the recommendations of our committee for a final decision and approval of a passing score. We go to great lengths to make sure all our testing is as fair and unbiased as possible. As Ezra points out, it would be HUGELY expensive to have to replace our question pool for every test because we revealed the questions which you missed to you. Surely you can see that those questions would be widely circulated by the time candidates sat for the next test, making them useless.

Re: [RE-wrenches] Testing new batteries
Hi Benn: Perhaps those batteries have just been sitting a little while, and need a recharge. Generally speaking, if you find that the batteries test reading are a little low, they are probably just a little discharged. After recharging the batteries, test them again. If those readings are low, then contact the manufacturer with the data. I have had great luck with battery manufacturers warranting their defective batteries in warranty.

Re: [RE-wrenches] grounding the Enphase inverter
Hi Mark, Ray, and wrenches: I agree that the grounding requirements can be onerous, but I have to interject that most generator manufacturers do specify a dedicated grounding electrode conductor. Also, I do not feel that a #8 ground is too big. Probably unnecessary 99% of the time, but with all the shorts and arced connections that I have found in j-boxes, I feel good about running a larger grounding conductor. With regard to the Enphase grounded with WEEB; which I have done many times, I would recommend spelling out the exact grounding method for the micro-inverters on the permit package. We should have this issue resolved before installation begins.

As opposed to having the DC power source actually run DC utilization equipment such as motors and appliances. It is interesting that the very language in the code descibes the inverter as utility interactive. Is it really correct to describe a UL174 inverter operating only in parrallel with the utility as a seperately derived system? To what degree has the Code failed to reflect the evolution of technology? Yes, battery-based inverter systems capable of powering a facility in the absense of a utility power souce do in fact become a seperately derived system which need to have a GEC. But to impose the same requirement on an inverter which cannot possibly deliver power to anything other than a system that already has a GEC seems to me to be a crude cookie cutter response to a far more complex situation.

While an application note from Enphase may state that WEEBs can be used as part of the grounding electrode system, I disagree with this concept and do not believe it meets the requirements or intent of the NEC as clarified in the 2011 NEC. The problem with a grounded PV inverter is that it requires a grounding electrode conductor (GEC) from the grounding point (on the inverter) to the grounding electrode. The 2008 and 2011 NEC allows for that connection to be terminated at the grounding bar in the service panel supplying the micro-inverters. There is no problem with using the WEEB to bond the rails to the modules and then to the Enphase Micro-inverter. From the micro-inverter, a bare 6AWG could be run to pick up each micro-inveter in each row of micro-inverters with splices made to a single bare 6AWG made with irreversible splices. At the rooftop junction box, the GEC could be irreversibly spliced to an 8AWG green insulated conductor to run unbroken to the grounding busbar in the service equipment.

Re: [RE-wrenches] Can I handle the voltage drop?
Hi Mark: I wouldn't feel comfortable with that scenario, either. Many inverters do shut off at 254V-255V, but most of them can be adjusted if you have the software and laptop for the job. Enphase generally shuts off when the AC voltage reaches 258V-259V. Keep in mind that just the Enphase cabling can add an additional 1.75% to the rise. I break my Enphase circuits into two sub-circuits of half length. Enphase is defintitely more tolerant of voltage issues than other inverters. Xantrex is the worst, but can be adjusted.

Can I handle the voltage drop? Folks, I am working on a proposal. It's a ground mount 300+ feet from the meter. There is an existing, near by run of #2 copper I can tap into. The desired system is relatively large, 64 amps AC max. I have modeled the yield using PV watts hourly data, applying a power loss based on the voltage drop at the varying current. This model shows a 3% loss in annual yield with the #2 copper. Because of the economics of the system, we can absorb this loss. My concern however is that I do not want the inverters to shut down when operating at higher currents. I do not want a high AC line voltage fault due to the voltage drop on the line. At the 64 amps max, the drop would be about 4%. Of course all the manufactures I talk with recommend keeping the drop on the AC below 1.5%. I am looking at using Enphase inverters which spec an AC voltage range up to 264V, or 10% above 240V nominal. What experience have folks had out there? How far can one realistically push the 1.5% limit and still avoid AC voltage faults when there is high voltage drop on the line? My guess is that everything would work out fine, but I stand to loss a huge amount of energy if the inverters are spending all their time faulting and resetting during daily peaks.

Re: [RE-wrenches] PV water pumping
Hi Jeff: I am familiar with that installation you mentioned, which runs all of the buddhist prayer wheels. We have added an additional 100 KW of PV at that site, and at the new temple, Cintimani. Those Kyocera modules that were installed there failed. I found that about 1/3 of the modules were producing 0-10 Voc, vs the 21 Voc specified. As a result, of the low string voltages,the SMA inverters were underperforming significantly or not turning on at all. Kyocera replaced the entire array with new modules, and paid us a fair wage for the trouble. I have spent a couple months of my life working there, which was very peaceful and interesting, to say the least. Each one of those prayer wheels has over a mile of prayers inscribed on a long strip wrapped inside of them. I think I calculated that their were nearly 800 of those wheels, spinning continuously. They say that those wheels send out ~500 million prayers a day!

Re: [RE-wrenches] NABCEP marketing
To become NABCEP certified, you only need to have installed 2 PV systems. 1 of those systems can be at a training class, and the other can be on your brothers house. All that NABCEP Certified means is that I studied a list of questions, and then passed the test. It is good to know that a handrailing should be 39-45 tall, and not 36-42. However, that should not come with any title, like 'Certified PV Installer.' The experience requirements should be more stringent. If it required some real experience, it would mean something, but NABCEP wants as many participants as possible, so anyone can sit for it.

Re: [RE-wrenches] Parallel wire runs to increase size
You shouldn't parallel wiring that way. That is not acceptable by code, and it is unnecessary. If the #10 is not sufficient just replace it.

Re: [RE-wrenches] Roofers installing solar = creative, new installation methods
Hi Joel: For many years, when Petersen Dean was Old Country Roofing, I would install the inverters and wiring for the Atlantis Sunslate roofs that they would sell. I liked that partnership. Also, I recognize that solar is less and less of a specialty anymore. Sooner than later, I would expect that solar installations will be installed largely by electricians, general contractors, and even roofing contractors (as long as they carry appropriate licensing.) However, many of my old partners, such as roofers who I have often referred, are now entering the solar industry. So my partners are becoming my competitors. They have that right. My hope is that whoever is installing solar, will at least provide a quality installation. What worries me about the system I serviced this week, where the modules were left sitting on a sloped roof without attachments, is that the roofing attachments is the aspect of the project that the roofer should be able to do best, but they skipped that step. That gives me some concern for the safety of PV system owners and their neighbors.

[RE-wrenches] Roofers installing solar = creative, new installation methods
Hi wrenches: Have you noticed that roofing companies have recently been trying to sell solar? One company thought of something that I had never considered. Listen to this neat story. I was servicing a job today, where a roofing company recently removed and re-installed a PV array on a 12 degree sloped roof. The funny thing is that the roofer didn't want to penetrate his new roof, so he and the customer decided to leave the panels sitting on the composition roof without any attachments to the structure. They didn't think it was necessary! Shortly afterward, the array slid down the roof, and a MultiContact connector came unplugged. The customer noticed that his system was not operating, and called us to the site.

Re: [RE-wrenches] EnPhase male whips
Sorry Kent: I am just not that motivated by this conversation to create drawings. I will try to explain one of the times when I choose to use the male cable. The site had 28 modules on one roof, but due to fire access walkways, and limited space, we had to place on module on a different roof. The main array was on a roof with skylights that broke up the rows of modules, so our Enphase strings travelled along the peak of the roof, then down to a lower row, then back up to the row by the peak (with a gap in the top row.) The end of that 8 module sub-circuit was located across the hip, and 15' from a single module that did not fit on the main roof. So at the end of the 8 modules we wanted a male cable, so that we could tie the end of the string into a j-box, transition to 3/4 conduit and then run to the other roof, where we could use a female whip to pick up the single module. We did not want to have to run 40' of conduit and wire for the one module, which would have had to jog down to the middle row and back up to stay under the modules, and would have had to cross rails. The other option would have been to use an extension cable (assuming that the 15' cable was long enough), but that would have required a 1-1/4 emt chase between the roofs to fit the extension cable end. With bends in the conduit, we question if we would even need a 1-1/2 chase. We decided to cut the extension ends, and transition to conduit in between. Essentially, this was just an extension cable, with 3/4 conduit and 2 j-boxes in the middle of it. I guess you could argue that we never need just a male cable, because we will always need a female on the other end. That is why I am not really complaining about the lack of male cable options, because the Enphase extension cable is a good solution.

The ground wire was then zip- tied to the rail to carry it to the point where it entered a junction box along with the rest of the PV conductors. The inspector was concerned with the fact that the bare copper was in contact with the aluminum rails and that this might cause galvanic corrosion and subsequent failure of the grounding. I have never encountered this issue before and I wonder if anyone else has and what was the outcome. As an aside: I do know that 10 AWG and 12 AWG solid bare copper wire can be purchased pre-tinned (maybe not tin per se, but coated). We did so by mistake. We used it up, but not before one inspector questioned its use for the purpose of grounding our system.

Make sure that your laptop battery is charged, because you have to turn off the inverters during the upgrade. It would be slick to bypass the utility or generator power to the site during the service. If the laptop turns off during the upgrade, it can be really bad, because it can result in having to pull the inverters off the wall and sending them back for service!) I can't believe that the original AGS software did not support 2-wire start! The wiring harness has 13 different wires for a multitude of gen start methods, but they forget the most fundamental one! How does that happen? Gen starting shouldn't be so complicated.

Re: [RE-wrenches] Working on DIY systems and Junkers
I don't mind servicing older, existing systems. It is fun to work with the older components, like APT power panels, SW inverters, and Trimetric monitors. I will frequently bust out the solder gun and repair old modules and components. On most of these systems, I will recommend upgrading some components, and will replace unprotected wiring. If something is a hazard, then I will repair it. I find that grounding systems tend to be the weakest link, and generally need to be replaced or repaired. Overall, I have been lucky to have reasonable customers who want their systems to be safe. Well, there was that one guy who was running his genny with the gas cap off, which started a grass fire just as I was pulling up Nick Soleil Project Manager Advanced Alternative Energy Solutions, LLC PO Box 657 Petaluma, CA 94953 Cell: 707-321-2937 Office: 707-789-9537 Fax:707-769-9037 From: R Ray Walters r...@solarray.com To: RE-wrenches re-wrenches@lists.re-wrenches.org Sent: Thu, January 13, 2011 2:27:09 PM Subject: Re: [RE-wrenches] Working on DIY systems and Junkers We've taken many of these on over the years: it can have a satisfying outcome, if the customer is really willing to pay to fix it. We don't even try to work with what's there; everything comes off the wall, and we rebuild the whole system using any decent parts that can be reused. Most customers report much more reliable operation after, but you still can't find everything. I try to stay out of the premises distribution wiring, and keep the work just to the PV, batteries, inverter, etc. This keeps it clear what you're responsible for, and what you're not. If pulling a permit, I write it up to specifically exclude distribution wiring. These days, I only take them on, if they are essentially buying a new system (batteries, more PV, inverter, or charge controller upgrade.) I often sell them a whole new power board, and offer a trade-in on their old usable equipment. Even reusing old PV is getting harder these days (rewiring an old array of 50 watt modules, often just isn't worth the time) Unless you've done several of these, I'd stay clear of them.

I like to bolt through the structural member, but have used toggles in some applications.

Re: [RE-wrenches] Battery based hydrogen incidents
Robb Cary was dealing with a lot of large scale telecomm systems with CD Technologies, so his scary photos were probably not from solar projects, (if that is any comfort!) He spoke of some projects with 50,000 2V industrial cells. I have worked with him for a long time and served on the board of Solar Sebastopol with him 5-6 years ago. I too have lost touch. I tried to reach him four or five years ago but his office said that he was retired and his cell number was disconnected.
