Re: [RE-wrenches] Ideas and racking systems for "stowing" ground mount PV array during snowy winter?

Hi Blake, I'm curious why the assumption that the snow will destroy the array - how about 3 rails instead of 2 under the modules? Blake Gleason via RE-wrenches March 26, 2022 at 8:39 AM Hi all, I think there's a lot of experience on this list with P

Re: [RE-wrenches] Ideas and racking systems for "stowing" ground mount PV array during snowy winter?

Coming back to this Blake - seems to me you need a platform type rack that has a tilt-up set of legs. The Nuance Osprey is such a rack - though I think they only go up to 35º but I think it could be easily adapted.  They use Earth Anchors but can also be mounted to sonotubes or even ground scr

Re: [RE-wrenches] Sol-Ark 15k

I've been using two gutters with multiple 12KW Sol-Arks Installs - one 4x4" that I mount immediately under the AC KOs using forward biased offset nipples (it's front face is just abouut 1/2" in front of front plane of Sol-Arks)  and then a 6x6" set back and down and reached with 4" nipples exte

Re: [RE-wrenches] EG4

Hi All Yes I’ve been working with EG4s for some time now. I installed 30 (154KWH) on 4 Sunny Island’s in Feb and that system has been working flawlessly. I’ve also done a 4 (20.5KWWH) battery system and a 6 battery (30.7 kWH) on single SOl-ARKs. And I’ve consulted in amd been monitoring some m

Re: [RE-wrenches] sol ark reliability question

I have a dozen Sol-Arks In the field and all systems have been giving solid performance . The MCU board upgrade is standard and super well supported and easy and usually done in a preventative context. I consider that a small price to pay for all the Sol-Ark can do and the overall performance an

Hi Kris What voltage do you have your charge settings at? I recommend that bulk or absorb voltage for lithium iron phosphate not be set above 56 V - there is no reason for it even though many manufactures suggest higher settings. In cases where total storage is sized generously enough I

Re: [RE-wrenches] Remote battery disconnects

Hi Esteemed Wrenchies, Love this discussion. It is clear to me after many years of watching this that the industry needs to have an Emergency Shutdown standard that includes an emergency shutdown of the BMS of every battery as well as the inverter's circuits including MPPTs if all all-in-one.

Re: [RE-wrenches] Service rated tap devices

Hi Mac and All, If you are about to do a Supply-side tap I'd encourage you to look into the many advantages of using a Feeder Tap instead - one of which is that since it's not on the load side of the Main the equipment need not be Service Rated. (not that you might not want it to be anyway.)

Re: [RE-wrenches] Nuance ground racking

Hi Dave, Yes we were one of the early adopters and installed a 32 KW Nuance system last year in CA. Mixed results though I think it's a very exciting concept and believe in it going forward - they are working out the bugs. The new version is much better execution as far as the above ground

[RE-wrenches] EG4 18kPV Correction - does have frequency shift AC Coupling

Hi Folks, Just wanted to make a correction on the EG418kPV of a statement made during the AC Coupling thread. The EG4 18kPV does have frequency shift based AC Coupling.  The confusion comes from the fact that like Sol-Ark there is a SOC set-point override feature for AC Coupling but the vide

Re: [RE-wrenches] PV watts question

Yes I’ve wondered about this too and there is much debate on forums etc about exactly how this works. Large PV plants have long used 1.4 order of magnitude ratios to maximize economics (but much of that was under “per watt” incentives rather than performance based incentives). However I’ve long won
