Re: [RE-wrenches] How many times can a rafter have a lag screw put in and out before it is no longer structurally sound? Some roofs getting their 3rd set of new shingles
Scott, For liability you might want a before and after inspection by a really top inspector that you trust. I would also ask your insurance for guidance. My insurance is always telling me that going out of business is the typical last straw for roofers.

I like the rafter sistering idea, as a solution, as well as moving the rails up or down several inches to get away from the previous hole. A third idea is staggering the mount pattern from rail to rail, which is something we should all be doing anyway to insure the loads are more equally distributed across all the rafters. Then we just change the pattern on the 2nd installation. Unfortunately I think much of this will be lost, since some of the companies that roofers subcontract with to do these remove and replace jobs are not always the top solar contractors.

It's a bit ironic that the changing climate is damaging the equipment we are utilizing to combat climate change. A lag unscrewed will damage a wooden member less than a lag ripped out. From your post it seems we are dealing with the former, rather than the latter. If your layout isn't changing there is a likelihood that the new mounting locations will be at our near the old mounting locations. This will be true for a rafter lag or deck mount screw. It seems to me the process of re-screwing in the same spot in a rafter is just as questionable as re-screwing in the same spot in sheeting. I see no benefit in deck mounting and many disadvantages. If severe weather is an issue I would avoid deck mounting unless you have vetted the decking and the applicability of the chosen fasteners to that material. I would not standing-seam mount without knowing how the sheeting panels are secured and finding a method to calculate how many clips are needed given the increasing wind loads. I see two questions about reinstalling screws repeatedly: 1. Is the rafter less able to support loads? Or, 2. Is the rafter (or decking) less able to retain the fasteners holding the PV to the roof? Speculation on the above: 1. Wood fibers adhere to each other. They are not like a bundle of straws. If you damage a fiber in one place, it is supported on either side of the point of damage by this adherence. My guess is by just withdrawing screws a few times you do not compromise the load handling ability of a rafter member. Site built rafters require different considerations than trusses. Site built are a wild-card and need to be considered on a case-by-case basis. 2. If you penetrate wood with screws multiple times in a small area, you are going to make that area "soft." Screw holding capabilities will be drastically reduced. Options that I see: 1. Flashed stanchions. The lags never need to be removed. 2. Blocking, to attach in new locations. 3. Sistering, again to attach in new locations. 4. Not deck mounting (IMHO). Anecdote: We had a tile roof mount inspected one August afternoon. The inspector insisted on looking in the attic. We asked why and he said this city has a particular concern about structural integrity of wood framed roofs. I was aware of this because I have had some silly arguments about this with the lead inspector. Apparently they have seen a lot of big-box solar company installers drive lags carelessly and had the lags blow out the side of the rafter. If they spot this they make the installer hire an engineer and design a system to sister the rafters to engineering standards. I totally get this concern. We use a rafter locator and are really careful. This is not to say we have not had a blow out now and then. You gotta have a feel for the torque resistance of a lag while seating. Thank you for bringing this up. As I said, fascinating (to this wonk).

Easier to read but still not a good sign! When I worked at HP in the 80's they struggled with keeping old equipment alive. It was terribly expensive and they just stopped after 5 years and let the secondary market do repairs. Even that was expensive and finally just stopped keeping any inventory.

Re: [RE-wrenches] Fortress Avalon
Hey Darryl, I got involved with the Schneider Home all in one (same thing as Fortress Avalon) Before that I was involved with another Schneider HV all in one long before Solark. Omnia failed to get to market. I get the hee bee jeebies with that kind of voltage offgrid. The numerous various failures of the LG hi voltage batteries. There is no way to replace the battery without waiting for Fortress to help. With 48v, I can go to Costco or Walmart and build a temporary 48v bank in 3 hours. Pretty simple requirement that I have.

We formerly designed and installed over a hundred Li battery based systems, mostly mobile installations but UPS and off-grid as well. Since 2018, we no longer do installations. Currently we sell our own Li-ion brand with many thousands sold and in use. We have not had any fire or explosion claims. Most Li batteries sold in the US are not UL1973 or ETL certified. Many batteries are very cheaply made to have the lowest price. Based on my experience I consider any battery not certified as potentially dangerous.

Last year I experienced something nearly identical to what you are describing. 3 ea. XW pros in an off-grid application. Things were working fine, but wanted to upgrade firmware for a comms issue I was having with closed loop BMS and Insight. After the 2.04 upgrade, when the generator would charge the system, voltage would slowly creep up and after about 20 or so minutes, voltage would hit around 250 VAC with a terrible high pitched grinding noise coming from the inverters. This issue burned 3 of the homeowners UPS and several LED fixtures. I was 99% sure this was a generator issue. After weeks of tech support calls, a new voltage regulator and multiple return service visits... and eventually one brand new generator... I had to come back to the homeowner with my tail between my legs and let them know that it wasn't generator related. Even after reverting back to the old firmware, it seems as though the software eventually affected the hardware. Long story short, homeowner was done with dealing with Schneider and we ended up swapping the Conext gear for 2ea. Sol-Ark 15ks and the system has been issue free for almost a year. Both generator run like a top. Sort of embarrassing to re-read this, but if I can help someone avoid the headache I went through, it's worth it. One easy test method is to deenergize your entire system, turn off batteries and manually bypass your inverters. Let the generator power the loads directly and keep a close eye on your generator frequency, voltage and THD. In my case, I found that the generator behaved well in bypass and terribly when the inverters were present. Good luck on this one!

Good advice Michael! I had one that the grid code got set by FW and reverting did not help. Had to start fresh. I certainly would try the revert as it is so much easier. There just is too much grid firmware being changed and it does not need to be done offgrid.

He also has 120 volt AC loads that run through a separate distribution panel where the only source is a 2000 Watt Honda generator. There is no inverter present. The batteries are charged through a Trace C40. He currently has a few ancient solar panels and a struggling Bank of AGM batteries. It's time for an upgrade. I can easily supply enough PV power for what he needs. He currently has a 9 kilowatt hour battery capacity that he was happy with when the batteries operated optimally. Nonetheless, I would probably future-proof him with a 10 to 15 kilowatt hour LiPo to double or triple his usable capacity. For convenience, obviously it would be nice to have an inverter to eliminate or reduce the generator requirement. But he seems committed to keeping his 12 volt distribution because it would be costly to replace fixtures. I think he would consider replacing the 12 volt refrigerator if he has an inverter. He definitely wants LiPo batteries. I don't like the idea of 12 volt direct from a battery plus connecting an inverter to that same battery. It is going to be hard to measure and monitor things. I am thinking about using a 48 volt battery with a single phase 120 volt inverter, getting him to change to a 120 volt refrigerator, and using a DC converter to give him somewhere in the range of 100 amps at 12 volts for his existing DC lighting and fan loads. Is this a bad idea? Should I stick with a 12 volt battery system? He does have a tiny 12 volt pressure pump which might be an issue for the converter. I'm not sure. I am a bit worried about the efficiency loss and capacity of DC converters and not sure how to size it.

The bad experiences on (won't say the Chinese name of inverter) was it had trouble starting a fire pump that was 120vac. it also had trouble with large 120vac air compressors. Even worse, not only did it have trouble starting the load, it shut down the inverter. I would not want that for sure it the fire was raging up the hill.

I'm not into either personally but was dragged into a Solark system two years ago. Doing my best to keep my back strong with transformer based inverters until I can support Midnite.

In order to effectively use a SolArk with lead acid batteries you have trick it. This process takes several iterations checking specific gravity, which means multiple site visits stretched over perhaps a couple months. The Absorb setting is ineffectual, so Steve's solution is to employ the Equalize setting to actually achieve Absorption. Carefully record the settings (voltage, duration, and frequency) that deliver a consistent specific gravity in range. On the rare occasions you actually need to equalize, you do it in person. When equalization is complete you return the settings back to your curated values.

Re: [RE-wrenches] Mate3s error vs. event log
Hi Kirk, It has been a long time since I used Optics and not sure if this will work but here goes. A few years back Schneider came up with a way to hard wire a tablet for a graphic shot of the system that the user does not have to do anything. It is on 24/7. I have a few older clients that need this. You would have to have optics working. Below is a video on how to do this with a Samsung tablet from Eric Bentsen. https://www.youtube.com/watch?v=VuGcZafueic=280s Dave Angelini Offgrid Solar "we go where powerlines don't" [1]https://offgridsolar1.com/ [2] [1] e-mail offgridso...@sti.net text 209 813 0060 On 2024-04-01 12:08 pm, Kirk Herander via RE-wrenches wrote: Hello All, I have a customer with a OB Radian GS8048A, grid tied, which logs a "charged parms met" message regularly.

Re: [RE-wrenches] Schneider CSW4048 / Lithium DD5300
Mine work fine closed loop with Discover AES only. I doubt there is much support on other batteries as they all use XW pro which uses the RS 485 protocol to close the loop with different battery brands. To get it going open loop you would use a custom battery menu and probably need an external battery mon and shunt. Ouch ! Sorry about that. Going to be a project! With an AES : 42-48-3000, 42-48-6650 it is just plugging in xanbus and you are done.

The CSW manual refers to document 976-0319-01-01 for specifics on Lithium. I have not been able to locate that document. Schneider tech support suggests try using custom battery setting, but it won't go lower than 56V when the battery specs request 55V max. I specified the CSW4048 inverter for a Lithium installation not realizing until too late that the CSW doesn't actually offer closed-loop BMS integration. Using the Insight device it does interface to the BMS and allows the MPPT controllers to integrate for BMS derived SoC based charge control. Unclear if the BatLev gauge on the SCP will accurately display SoC values from the BMS.

The LG charger probably generates the Heartbeat signal you need to fool the contactor to be on for charging. I Think! My experience is with the 48V RESU 10 and not the RESU 10H that is a 400vdc battery. There were a few people on here with 10H so hang on.

I have access to the correct charger for this purpose. However, I have searched the Internet and Youtube and cannot find any instructions that explain how to operate the charger and recover the LG battery. Does anyone on this group have experience with this situation and can help?

Re: [RE-wrenches] Fortress
Hi Peter, I was called in to consult on a new existing 4x Fortress E flex / Schneider XWP system that worked fine open loop but never communicated with the Schneider gateway. Fortress to their credit sent a tech out and he did Fortress FW and a PC exchange. Still not working. The owner was upset and replaced with Discover AES 42-48-6650. There was zero configuration to do which surprised the installer. Worked fine closed loop from the start. I do not like to be negative about companies in North America and I still think Fortress could have fixed this with more time.

Gen shuts down if running. Power is off. Not just the PV via Tigo modules. Had to develop client instruction sheet as to how to power up after a shutdown. On one hand, I can see why a single point shutdown is desired outcome. But it concerns me that it's vulnerable to abuse.

Re: [RE-wrenches] Big Ag water
Just did one. You have to do the math for costing the grid, a genset, and solar direct. The genset usually wins if the grid is not an option. You can easily find/replace pumps that are not solar direct. If you do the solar, you still need a genset and the electronics to support it. It is not an easy thing to do if someone is not living there. Most Ag run big gensets if no grid is available. If you can add the grid, it will improve the property for the owner.

Kirk, Can you reference your paper on this? So many variables and each location will be different. Most dual axis trackers can always be left flat or any angle so that does not make sense to me. You have to design for winter offgrid if the location is worth it. Or, alot of hours on a genset. Super large arrays in your area will help give you more days/hours before you need the iron genoa. You have to decide if it is worth the money. The home has to have the ability to shed some loads also.

However a paper I recently read (1), makes a compelling case for a much shallower tilt in situations where the cloud cover is so heavy that "diffuse" solar radiation is all that makes it through. They indicate that under those conditions a horizontal array will produce significantly more energy than even a two-axis tracker!

Re: [RE-wrenches] XW Drop in replacement inverter
Hi Chad, Yes XWpro 6848 is a drop-in replacement. Exact fit & all connections are the same as way back to 2006 when the "grey box" XW 6048 was sold. You need a connext insight home or facility device to do the initial configuration. It is a one time need for the insight home device to set the mode for offgrid. There are numerous new settings that will not work with the old SCP he has, but you do not need them for a replacement. You should not need to change firmware either as long as the system was working. Most new firmware is for the closed loop support of 10 different LFP battery systems and new grid features. There is one LFP battery Discover AES that all settings are hard written and read by connecting one xanbus network cable. https://solar.se.com/us/en/xw-pro-commissioning-guide/ Dave Angelini Offgrid Solar "we go where powerlines don't" [1]https://offgridsolar1.com/ [2] [1] e-mail offgridso...@sti.net text 209 813 0060 On 2023-10-24 2:17 pm, Chad Waits via RE-wrenches wrote: Wrenches, We have a client that had us construct a solar trailer for them back in 2014-2015 timeframe.

The main DC battery breaker inexplicably tripped the same day; inverter etc. are all OK. How many hours? "A Lot." I can't be more specific b/c the electronic box with the display is black. The 12v cranking battery seems to have adequate energy but the black box is truly "blacked out" & doesn't respond to the red Run button. Three glass fuses near the ADC2100 control box all have continuity. The physical space in the power shed accommodates this machine housing but I doubt if any new machine would fit as well.

I have only a fuzzy picture of ours, but squinting at the p/n, ours might be GM28707. Are they all interchangeable? The ideal case would be if one of the Wrenches has a "known good" control box even if it's used or dusty. Clients might be sad if I persuade them to spend $1k or more for an eBay part then we put it all together only to find the machine still won't run. Contact me off-list if you have a part or parts to sell, or a "value added" parts vendor to suggest. We're in southern Colorado. If something else may have also been damaged, can I get suggestions as to the likely culprits? Finally, how far should we go if the clients really want a new lease on life for this machine? Are there shops that could do an engine overhaul? Assuming that the generator windings are OK, are there bearing replacements or other TLC items to address if we haul it to a shop?

Re: [RE-wrenches] XW Pro failures
It must be an XW+ that died. The XW pro field circuit validation testing beta was complete in early 2019. That XWP is still working fine for me. Not many failures unless the installer did not use surge protection. If it was an XWP and you filled out the 10 year warranty, they might have your back still. If you troubleshoot xw and find it is the power bridge PCB, I see them available on Ebay. Schneider has not provided parts for out of warranty devices for 10 years now.

Re: [RE-wrenches] Well pump with Sol-Ark
The Franklin with capacitor Jbox at top of well helps with the surge. It is not what you would call soft start! An ammeter (or a loud generator) on a soft start pump will tell you what you have. A nice slow over 10 seconds ramping up of amps or gen noise when the pump is energized. You won't get this with a Franklin and Jbox.

Re: [RE-wrenches] Well pump with Sol-Ark
Look at a variable speed pump from Grundfos. Not as many choices for large pumping apps. The SQ Flex pump is basically a VFD when used with the controller. It can direct run from solar which tells you there is no surge. Even the SQ pump without the controller will soft start and should work with any inverter built for offgrid.

Re: [RE-wrenches] Propane range options for off-grid?
Hey David, I wish I could convince my clients to use a no AC power source ignition for baking and broiling. I gave up years ago and never could convince my wife. The power system needs enough storage for winter use of appliances. The ranges now all have convection cooking and some can air fry. There would be a higher divorce rate by trying to avoid the use of 500 watts to run an igniter. Wife acceptance factor or significant other. If I had to, I would specify another Premier or the Unique. I have a few clients that have a 2nd range in the garage and that is their spare. It avoids the need of service in the dead of winter offgrid. It would be a fantasy to have good appliance service where many of my people live. Good Luck!

Re: [RE-wrenches] Iron Edison Lithiums
Yes Iron Edison is closed. They had an out of business sale earlier this year. The epoxy fix of leaking fluids is best done by using a fast cure blend and expanding out until the leak stops. You can do this with a diesel fuel tank leak or an oil pan leak. It just needs to be clean and dry long enough for the epoxy to cure. The final coat can be with a quality epoxy like JB weld.

I'm sorry that I inadvertently fueled an untrue rumor about Fronius USA. Chris, I should have tracked you down for the correct answer before putting my question on the List. I will also correct this with my Greentech branch manager on Monday, Heaven permitting. I freaked out when my Greentech rep told me Fronius had left the building but I'm glad I don't have to re-shop the string inverter component after all. I did an AC coupled off grid project using Fronius Symo in 2019: No Drama, No Trauma. For those Wrenches who've wondered, "Why, Mick, why..." about off grid AC coupling: most of the rooftops that need PV for my 2023 opportunity will be inconvenient for running DC wires to the battery location. These same rooftops, however, will have AC sub-panels close by, so I had an "A-ha, negative loads!" moment. At least some of the PV will run through a charge controller in any case. I think the wattage from any AC coupled string inverters won't show up on Schneider Insight, so that's another reason for me to heed those Wrenches who suggest DC coupling for all of the PV. Thanks to all who've contributed to this thread. I think the thread should now extinguish & moderator Michael may wish to delete it from the archives. I appreciate accessing the "hive mind" on various 2023 PV inverters and again, Chris, I'm sorry to have caused a temporary smudge on Fronius USA. The Wrench List is the Bomb!

This is an aside, it's kind of hard to see, but for seperation, we attached the pv circuits to the back of the gutter using through bolted adhesive backed cable tie holders. Often we use gutter dividers. They originate in the tall cabinet at the end which houses controls, secondary PV disconnects, AC and DC egauges, Tigo hub, Battery hub and (Lynk II). On the opposite end is a similar cabinet for the collection and distribution of AC circuits. Also, above and below the batteries are small gutters for communications and CT wires that run from the transfer switches to eguage. One transfer switch to alternate usage (alternating relay) or bypass between Gen 1 and Gen 2, and the other switch to select inverter or generator power, locally or remotely. In the AC cabinet there is a 400a contactor and time delay relay to achieve a generator cooldown as the janky Sol-Arks don't do that and it's hell on new diesels not to have that function. ___ List sponsored by Redwood Alliance Pay optional member dues here: http://re-wrenches.org List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org There are two list archives for searching.

Re: [RE-wrenches] 200a manual xfer switch w/ small aux contact : who makes it?
You saw the back-up control switch from Schneider? Probably not what you want. https://solar.se.com/us/en/product/backup-control-switch/ Might be good for something else? Whole home or partial home backup made easy. When paired with Schneider Electric XW Pro inverters, the Backup Control Switch (BCS) automatically disconnects from the grid during an outage, allowing the system to provide backup power to the home. Certified to UL standards for USA, The Backup Control Switch is used for larger XW Pro systems requiring up to 200 A rated MID or service entrance installation. Flexible Installation * Whole home backup or subpanel backup with up to 200 A rating * Service entrance rated when installed with a main breaker * Top or bottom entry for grid input * Optional non-backup circuit, making it easy to backup an existing panel and remove select non-critical loads * Configurable for export limiting with integrated meter Reliable * Fast 50 ms transfer from grid connected to backup power operation * Reliable backup power and load starting performance with the compatible XW Pro inverters * Connect up to 4 XW Pro inverters for up to 27 kW continuous and 48 kW peak backup power capability * Outdoor rated enclosure * 10 year limited warranty Dave Angelini Offgrid Solar "we go where powerlines don't" http://members.sti.net/offgridsolar/ e-mail offgridso...@sti.net text 209 813 0060 On 2023-07-26 3:24 pm, Mick Abraham via RE-wrenches wrote: Hi, Mechanix~ My off grid project needs dual 40kW diesel generators with easy manual selection between "A" or "B".

Hey Howie, Can't remember but did you try disabling the charger in XW+ for a pulsation test ?

The fluctuations happen anytime the AC coupled inverter connects to the XW+'s "grid", not just when the batteries are full. The frequency only changes about 1/10 of a herz when it connects, but it doesn't matter what the voltage is of the batteries, the pulsation starts. Going over the settings with Eric Bentsen, we shut off the AC coupled option to prevent the frequency shifting - this made no difference. We do have a contactor installed that disconnects the inverter from AC when the voltage starts elevating past the charge voltage and it has worked well for years. If I set up an AC coupled Off-Grid open loop system in the future, I'm thinking that I would look to disconnect the DC input as the batteries reach charged voltage - generally an easier cycling for the system to endure. There is also a smaller, legacy DC coupled array in this system which takes care of the finishing charge of the batteries through a charge controller. Again, it has all worked well in the past, only having any issues with AC fluctuations due to having the generator charging load set too high for the existing generator. This was solved by simply turning down the charge rate of the batteries and the visible light fluctuations stopped.

Is the output with-in spec? Rock solid 60 HZ right. Do an AC bypass of XW with the genset and check for flicker symptoms. Are they on Insight? They really need it for you to monitor. Are there any faults, warnings or events ? Check history. There are a few settings in the old XW+ that could have been glitched by a surge or nearby lightning strike. XW+ could have a damaged FET. Open the unit and do a visual. There would be a smell and transistor fragments on the bottom right side of the power bridge. 90% of XW failures have visual evidence. While you have it open, Check the DSP sensing and control board, both LEDs (light-emitting diodes) D24 and D25 are on. Last thing is a DC power down of the unit and the DC buss for 5 minutes. If that does not work, then a reset to factory values. This is off an old list I got from Support many years ago and combined with my findings over the years. Really rare for this kind of weirdness and why it would be getting worse without visual evidence. Good Luck Howie!

When the batteries were moving toward full, if the charge rate was on the higher side via generator or solar (AC coupled w/SolarEdge 6kW and DC coupled with an FM 80), they would start to get pulsating lights similar to symptoms of other older inverters when using a generator for charging. The solution for this pulsation has usually been to kick back the AC charge amperage just enough so the pulsating calmed down to a tolerable inconsequential level.

To my knowledge, no settings changes we made within the previous year, and these clients would be loath to make any changes, so I doubt there were any. More puzzling is the pulsating has started to happen at seemingly random times not related to charging. It happens at night or pre-dawn mornings without the generator, or during the afternoons with solar charging. And it is getting progressively worse.

First, I don't know of any stationary battery systems that have C2 charge ability, many not even C1. A 20kWh bank C2 rate would be 40kW or over 770Amps @ 52V. I have 10 years experience with Li batteries, (hundreds of Li installations, mobile and off grid), and thousands of LiFeBlue Battery customers, low current charging works without issues. Most of these systems charge at the high end 0.35 C rate or less. Jay did not mention the bank size so we don't know the C rate for the 30-50 Amp recommendation. But I guess it is far lower than 1C. Long absorb (CV) times may cause a cell to saturate resulting in rapid voltage rise and the BMS protection inhibiting input current. This sudden loss of load (essentially a battery disconnect) can cause havoc with some inverter/chargers and PV solar controllers. In our experience, the best method to set Absorb times for any Li system is by trial. If the cell voltages are staying relatively close during discharge (6mv in the attached image), then balancing time (> 3.55V CV) is sufficient, whether it is 0.1 hours or much more.

While you don't have to get them full all the time like lead, as long as you are cycling regularly, it is still a good idea to get them to full regularly. Now if they are a backup system or not being cycled, they should not be held to full all the time. This can accelerate damage to the cells. Where we see the major mistakes are the absorb timer settings. Too many people are setting the absorb timers too short, especially if they have parallel modules and are not running closed-loop communications, or the batteries can't communicate with each other or the chargers. In these cases where you have 2,3,4... more batteries in parallel, the absorb timers can help balance them as the batteries that don't need balancing stop charging, while the cells that need the extra time get that time if you have longer absorb timers.

And now that Multi MPPT charge controllers are becoming more common (like Victron's 450V 200A charge controller with 4 MPPT inputs), it would be nice to have some kind of AFCI that was totally stand alone, so you could have one on each MPPT... one or two strings into each AFCI.

I've read the manual and it's not clear if it can function without the Xanbus connection. Of course, I don't think Schneider wants you to use it with other products... but I'm thinking the AFCI might functionally work... I figured one of you guys might know...

Re: [RE-wrenches] Fwd: Schneider SCP / MPPT 80 600 / XW+ / Gateway questions
Good advice from Tump, please use it! The main issue is we need to feed back to Schneider that XWP should work out of the box for Offgrid. This is how all of the previous models did. The California and Hawaii rules for grid have taken over. When I beta tested XWP for offgrid it was offgrid friendly. The firmware updates changed how XWP behaves for offgrid, in some modes. I have always thought they should build a model that leaves out all of the firmware for the grid and is just purely an Offgrid model. They taught being born offgrid and it is pretty bulletproof once configured. You can see that it mostly is fine offgrid Greg but that could change. Please tell them to consider making the default IEEE and thank them for keeping the SCP alive. Your 4 X XWP system is much easier/faster to install now with the new 200 amp panel Schneider makes for big systems. Firmware being ready very soon for offgrid and it works fine now with the grid.

Re: [RE-wrenches] Schneider SCP / MPPT 80 600 / XW+ / Gateway questions
It is pretty well laid out on the website for 3 + years that you need to use Insight. You should also read the installer info. https://solar.se.com/us/en/2021/06/29/essential-advanced-resources-for-installers/ SCP will work for some basic functions but is out of memory for XWP. Use for indication only. I am guessing that you did not program XWP to set the IEE region code as above in the installers manual? This is probably causing some extra issues for you. You do need the password and I can send it if you do not have it? Good Luck.

Just replaced 4 XW + 6848's with 4 XW Pros. Updated the Gateway to rev. 1.17 and the Pros to 2.04. Have some questions/observations so far. System: Off Grid with 4 XW Pros, 18 MPPT 80 600s, 2 SCPs, 1 Gateway, 1 Battery Monitor, 1 AGS. 3000 ahr of NiFe batteries. 36 kW Kubota Genset. I tried using the Inverter SCP to program settings on the new inverters and it took everything but when I checked on InsightLocal the settings had not changed. They were all still default so I had to go through it again one at a time through insightlocal. I'm guessing the SCP no longer works for programming with the Gateway? Can anyone confirm? Programming used to work through the SCP with the old XW+ inverters and firmware. Tried using the Solar SCP to change settings on the charge controls but had to use insight local to change each individually. Used to be able to use the "copy from" function which was a real time saver. Wondering if anyone else has run into the same problem, or if it works for them, what am I missing? Is there a cool way to change one setting with insightlocal and get it to change the other 17? Observations: - looking at the CC's via insightlocal, under configuration -> advanced ->controls - I set all chargers "enabled" but the next day or so they all go to "disabled". They all still work though. Doesn't seem to affect operations. under configuration -> advanced ->charger settings - I have the first CC set to "primary" and the rest to secondary. No idea if that's right or not. seems to work. Options are "stand-alone, primary, secondary and echo". I could not find definitions in the manual on them. - looking at the XW Pros via insight local, under configuration -> advanced ->controls -> Backup Mode - I disabled BAckup mode since I'm not backing up the grid.

I know some things have changed since then, so I'm circling back and starting a new thread. In NY one of our inspection agencies (NYSERDA) requires bonding of metal roof panels below the array, as well as within a 3' perimeter of the array. S-5! in combination with Ironridge is now listed to bond the roof under the array (so long as you hit every pan with an attachment) but this doesn't solve the problem of trying to bond within the 3' perimeter. For installs where we are only 18" from the ridge, this means we are required to bond the adjacent roof as well. Whenever possible we install Illsco SGB-4 lugs under the ridge cap. But more and more we're finding roofs where the ridge cap feels inaccessible, tricky, or where we simply don't want to get into roof warranty issues associated with opening up a prior contractor's work.

Re: [RE-wrenches] Schneider Conext SCP
September 2008 Schneider bought Xantrex Inverters & Solar. The XW and later CSW became a Schneider brand and the Marine and Mobile stayed Xantrex. Schneider later built the first 600vdc MPPT. Later Combox built an excellent Cloud based monitor Insight. It is good news that the SCP will be available again and for now the Marine Freedom/xantrex (black color) SCP can be used with a firmware update.

Or if not, one inverter runs all the time as a grid source ( grid forming) the second inverter (grid following) runs in Grid-Zero mode, with "off-set" set at 30 Amps. If the load is less than 30 amps, the grid-following inverter carries the load. (The grid-forming inverter supplies the grid signal, and the following inverter carries the load.) When your load exceeds 30 amps, the extra current comes from the grid-forming inverter. The Radian can pass up to 50 or 60 amps from the forming inverter. You can get 50 to 60 amps to the load when you add the forming and following inverters. Errors: this will double your parasitic load, I have not done this so beware.

Re: [RE-wrenches] active vs apparent power readings with solar
My metrology experience is he needs to prove it with a second meter. In a lab setting, at least 2 of 3 calibrated meters need to agree. I would also ask Fluke.

My gut on it is that there is some sort of measurement reading error, and that the power factor should be around 1. The electrician is using a Fluke 3540FC power monitor and has provided a spreadsheet comparing active power to apparent power and calculating power factor. See below (you might have to open the image and zoom in to read it). This measurement was taken with a PV system running, presumably sending some power back to the grid. Note that the phase B active power measurement is negative (PV exporting to grid) and that the apparent power is positive. This nets in a power factor that is crazy low of 0.05. Does anyone have experience about whether a meter like this can properly measure these readings - maybe there is a setting error or it can't deal with negative readings?

Its not just max strings, but max # of cells, and that's double my maximum. You mentioned they use it pretty hard, so that's the other big part of how long L16s will last. If the customer is barely using the available capacity, I've seen batteries last closer to 10 years, but in this case, I think the remaining cells are close to finished. I'm into using batteries for as long as possible as well, but customer and installer suffering come into play, as well as the fact they'll use much more water at the end of life, and cause a lot more corrosion damage. Not to be a turd at the pool party, but its not reasonable to plan on another 2 years of service. My guess is that you will probably have more cells fail by the time you return with the prorated warranty replacements. Certainly rolling into the summer months, more cells are going to start failing like pop corn. (Pop, pop, pop) Fortress is a good battery, but some of the programming, (especially LVD) can be tricky with older inverters. I had to use the aux out on the CC to switch off the inverters. IF the inverters are Outback, they have a remote switch, if its something else, you might have to actually switch off a relay on the AC output.

Saying this again, you all should tell Schneider this. BTW, a tablet can wifi station mode connect to a non internet installed "conext home" with a saved password. It also can be set-up as a "user" and no password is required. Neither of these require wifi at the home. It is all in the 3 ways to install conext home or facility for configuration. Maybe this is what Eric Bentsen was telling Glen?

The XW Pro/Discover AES pairing makes up 2/3s of our installs. Right now I have a client who's Insight Home is glitching and drops out his smartphone connection. Without the SCP He'd be in the dark. I just purchased an SCP off of Ebay for 700.00 for a system we are building for a retiree who uses a flip-phone and doesn't use the internet. Him having to login in to Insight on a tablet every time he wants to see SOC would be laughable.

As limited as the SCP is, I think it serves a very important function in system operation. I'm all for removing unnecessary components, but don't paint the windshield black. Schneider should offer a Xanbus tablet if this is the route they want to go. On Mon, Apr 3, 2023 at 10:29 PM Maverick Brown via RE-wrenches wrote: The key word there is Cobbled. The off grid or grid interactive (battery backup in case of grid down) world really needs to rely on a smart phone? Why couldn't Schnieder go the extra step and put a display "with enough memory" to support legacy and XW Pro equipment on the Insight product family. I.E. Cerbo GX with display from Victron. Schneider has all these cheap Chinese all in one product competition with display screens built in and some other products like the most excellent Outback Radian that has yet to delete the Simple Man's display. I understand the potential semiconductor shortage. I just hope Schneider can balance their approach.
