[RE-wrenches] Lithium batteries
Howie, I’ve used a few different brands and am currently using the Discover AES, I have a quad stack of the coupled to an dual stack of XW inverters and they are working great, As for another post comment that these companies are looking to be bought out, Discover is long time battery manufacturer and I feel pretty confident they will be here to honor the warranty. If you search YouTube you can see a video Discover and I did on my wood shop. Jason Andrade West Coast Sustainables > > >> Hi Folks, >> About to spec my first Lithium battery backup job.

Re: [RE-wrenches] Aquion Batteries
As for the Simpliphi I have them in a few projects one being Governor Browns offgrid home and my own off-grid residence is powered using them. I recently re-engineered the Outback IBR3 for the phi 3.5 and made an advanced version for my own. I purchased a flexnet battery monitor and used all three channels for the IBR I have a spare Flexmax80 that powers a hub 4 and a second mate 3. You are able to aggregate this data into optics and overlay the two. I’ll admit I haven’t had a lot of time to tweak with it but I think you can see it as an optics preview through outback. I agree data on the Lifpo4 is critical and my understanding is Simpliphi will be releasing a version soon that has comms. I also have a Discover AES bank on my off grid woodshop consisting of 4 of the 6.5 coupled with three of the older xantrex xw inverters this is a great platform so far and you can see the battery as a device on the scp, you can also direct connect using a usb to usb cable to the battery and upload firmware and see the battery specifics Jason Andrade West Coast Sustainables Sent from my iPhone > On Jan 23, 2019, at 2:21 PM, re-wrenches-requ...@lists.re-wrenches.org wrote: > > Message: 1 > Date: Wed, 23 Jan 2019 16:08:55 -0600 > From: Darryl Thayer > To: offgridso...@sti.net, newrewrenches > > Subject: Re: [RE-wrenches] Aquion Batteries > Message-ID: > > Content-Type: text/plain; charset="utf-8" > > I have used Simphiphy.

Re: [RE-wrenches] Ibew is working to exclude C-46 contractor?s from installing Batteries.
Ultimately I think handing off ESS just to the C-10 is unjust and if its a real concern they should make it a separate classification, I have a C46 and the ESS project that I just completed for Governor Brown’s off grid ranch was what I feel is top notch work that shows a C46 can hang with the C10 :) West Coast Sustainables Jason Andrade 530-410-4745 From: RE-wrenches mailto:re-wrenches-boun...@lists.re-wrenches.org>> On Behalf Of e...@harvesthesun.com <mailto:e...@harvesthesun.com> Sent: Friday, March 23, 2018 10:40 PM To: RE-wrenches mailto:re-wrenches@lists.re-wrenches.org>> Subject: [RE-wrenches] Ibew is working to exclude C-46 contractor?s from installing Batteries. As a C46 since 2011 I'll contend that though the license may have its origins in thermal, according to the CSLB the designation is for both thermal and PV, and that is reflected in the licensure exam (to be licensed as a C46 one must be familiar with PV). What one does in their profession, whether ST or PV or both, after passing the exam and becoming licensed, is up to the contractor. I for one have done little ST over the past 7 years, and as a result of my PV work, have more battery experience than my C10 peers - speaking only for the C10s with whom I work and those I know. If the CSLB decides that batteries are the domain of C10 contractors and not solar electrical contractors, which would be erroneous IMHO - being not reflective of the reality of many C46 contractors today, some whom have been in BBU as long as BBU has been in solar, then I imagine the C46 holders that do BBU work will seek to add the C10 license, as would I. Until then, I will join CalSSA in advocating for the s tatus quo. Thanks for sharing, Jason. Peter, you can reach me through Byers Solar, we're a CalSSA member and C46 contractor (under my license).___ List sponsored by Redwood Alliance 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 List-Archive: http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org
[RE-wrenches] Ibew is working to exclude C-46 contractor’s from installing Batteries.
Hi at this point I believe this is a California only issue, but I was contacted by CalSeia today and was asked to be involved in a discussion regarding a move where only a C-10 contractor can install a battery based system This was news to me but they sent me a pdf outlining the issue and I will read it over this weekend has anyone else heard about this? My instant response is what special training does the c10 have that the c46 doesn’t ?

Re: [RE-wrenches] Grundfos SQflex
I have this same situation with my off grid well, I have a grundfos sqf5-2 and the yield wound up being .25 gpm. Originally I ran it on 2- Astronergy 235 and made a timing system using a sprinkler timer and a midnite kid controller it was tough to control the production as the power varied and was limited to daylight hours. I ran ac power to the control box and now use a simple AC wall (pump draw is 400 watts) timer that up to seven daily cycles and control the pump times calculated on the recapture rate of the well which varies with the water table. I also use inline water gauges to help determine the amount of water I can pump per cycle because the amount drops so much in the summer. I went with the controlled time method over restriction as it was going to have to be extreme in my situation, there is a product out there I read about the dole valve that can regulate the production to 1GPM http://www.pumpsandwells.com/mm5/PDFs/Dole%20Valves.pdf without messing with the power directly.

I scoured the NRCA manual, which does not really define "penetration," but it does say in the shingle manual: "Penetration Flashings: There are many small penetrations that need to be flashed into asphalt shingle roof systems, such as vent pipes, exhaust vents, exhaust fans, furnace or water heater flue pipes, electrical standpipes and others." There is also a graphical figure showing these various penetrations. The one thing these all have in common is that there is a substantial air gap cut fully through the roof plane. It occurred to me that ridge caps and vents on shingle roofs use exposed fasteners to nail or screw them to the decking. The NRCA manual says about this: "Exposed fasteners should be sealed with elastomeric sealant or asphalt roof cement on the last ridge piece of a run, at the intersection of hips to a ridge and at the intersection of a ridge to another plane." Also read the Snow Guard section for metal roofs, which allows attachments sealed to the flat part of the roof pan with sealants. Until the manual specifically addressed the solar "attachments" and "fasteners" we are debating about, it's open to interpretation. ___ List sponsored by Redwood Alliance 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 List-Archive: http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org

Re: [RE-wrenches] 208 3 phase Off Grid Inverter
By using the Magic stacking on the Outback I thought you could parallel more than one inverter per phase in three phase mode, I have heard of reactivity issues with this while attached to 3 phase condenser units I would suggest contacting tech on this. This would be a though call for me I would probably go with the Sunny Islands AC coupled myself I have some great systems out there using the SI equipment. Jason Hi All; I'm exploring options for an off grid project with an existing 30 Kw Kohler wired for 208 vac 3 phase. The generator runs some 8 hp air compressors, so rewiring it is not an option. We're primarily interested in reducing gen run time from the current situation: 14 hrs/ day. So far, only the Outback VFX inverters seem capable of being wired in 208, 3 phase, but according to the manual they can only be stacked 1 inverter per leg. This limits the system to only 3 inverters total, or 10.8 kW. I would like expandability beyond this. 1) are there any other inverters available that I'm over looking? 2) Should I consider a transformer to convert from 208 vac/3phase to 240 vac/ singe phase? We're not going to even try to run the compressors, just the other single phase loads, mostly 120 vac, but we have a couple of small air conditioners, that are currently running on 208 single phase. I believe they would run fine on 240 vac, as they have a name plate rating at 230 vac. 3) We may possibly run 2 separate 3 inverter stacks and only tie together at the battery, but otherwise they would not be connected. This seems inefficient, and would require some load balancing of the various inverters.

I?ve had absolutely miserable tech support from Morningstar so I want to drop the line but I need something that will handle 2 60 cell modules in the 250w range for off grid applications. I use a Blue Sky for single panels and a Midnite Classic for three or more but in the middle the only one I can see is the Morningstar. Outback, Midnite and Xantrex are all overkill for just a couple of panels unless they want to expand in the future. ___ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Change email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org

Bergey's been dragging their feet as to why this is happening; they're saying it's probably an "upslope site" where the RPM just gets too high, among other things. Metering tests prove that the stator is OK. They also said that Midnite Solar has a 'clipper' to prevent overvoltage; do any of you have any experience with this device? It's ~$1200, and of course there is no mention of this on Bergey's web site or in their XL.1 manual. I have several other XL.1s in the general area, but they are on their old 24V controller. So I am looking for more information on anyone who's using this 'clipper'. Please feel free to contact me off list. Thanks!

I don't have first hand experience with the Clipper yet, but I have over a decade of XL.1 experience and many years with Midnite's electronics. The Clipper is exactly what is needed. It also moves the rectifier down to the ground, and offers a braking disconnect system to shut the turbine down completely if needed. The Classic by itself isn't really controlling the turbine speed, and counting on the XL,1 mechanical governing design by itself is definitely full hardy. Unfortunately, Bergey's new staff is not really up to full speed yet on what is needed to make their turbines work long term. At least they've abandoned the old XL.1 controller. Hopefully the turbine itself hasn't changed too much; I've seen them survive some very high speed winds and direct lightning strikes.

[RE-wrenches] AC Backfeed from Radian.
If you can get the serial number off the generator for me I can access kohler and get some info as a kohler dealer. The new ones are having controller issues and there is an updated controller. When meeting with the generator tech ask them if they transferred the setting from the previous controller with site tech.

[RE-wrenches] Ungrounded P.V.
Wrenches, I have yet to do a Transformer-less inverter and am understanding that they are an ungrounded system and that both the positive and negative of each string will need to be disconnected. I started with the sma SB series and now find myself using mainly Enphase. The SMA TL dual mppt lighter weight inverter has my attention, especially with AB327 Knocking on the door but that's another topic.

[RE-wrenches] Subject: Re: Best Ground Racking?
Racking: I used Prosolar for a long time and then switched to Iron ridge, I am pretty happy with it in all areas but the rails are pricy. Things I like -It has minimal deflection when tightening, but you have to tighten the Ubolts evenly. -The new mid clamps have teeth that penetrate both the module and the racking so you do not need weebs for module grounding. -End caps for sealing the rails are cheap. -It has slots like uni-rack that allows for a decent amount of adjustment. -As for wire management, there are two types of stainless rail clips for managing enphase size cable or attaching up to four pv wires on parallel rail runs. -When using central inverters I run all of my inverter to module cables in emt-heyco stain reliefs to MC connectors this turns out extremely tidy -For the grounding I use a weeb grounding lug that sits in the top rail with a 7/16 stainless bolt that allows for a strong connection. Things that do make it tedious there are a lot of stainless bolts, I use pentrox as a anti galling compound, what do other people use? when installing a micro inverter system you have to get all of your inverter mounting bolts in place before installing the cabling, they have to be end loaded, I would prefer and bolt similar to the mids that twists and locks in.
