Notice how you were reaching over the battery at 3:45? I believe that is a violation of the working space requirements of the National Electrical Code. Six inch depth difference is the limit. 110.26(A)(3).
Excellent choice of equipment. These are among the best options for multimodal ESS. Fortress makes a DuraRack cabinet that can house both the inverter and the batteries. The Sol-Ark 15K, although outdoor rated, is not recommended to be installed outdoors. Another helpful addition, to keep the eFlex batteries at their recommended operating temperature is installing a small DC coupled DIN rail mount heater and thermostat. To uphold the warranty on these batteries, and get 8000 cycles you want to operate above 10 Deg C(50 Deg F).
Thanks. We tried to source the full enclosure but had a hard time finding a distributor out here that could get it. Luckily in sunny San Diego we have some mild temps.
Honestly it think it’s a great solution. We actually have some of the PowerPro units on order for a few jobs coming up; I’ll do a video. We are sticking with Sol-Ark for now in regards to the inverter just because of our relationship with them in the event we have a problem (which hasn’t happened yet). Maybe we will try the 18k at some point, but then that’s a whole other monitoring platform for us to integrate.
So I'm looking to upgrade the capacity of my current Solar Edge/LG RESU system with a SolArk 12k and Fortress eFlex combination. Are you saying I can still use my existing LG and Solar Edge system as an additional AC coupled source for charging the eFlex batteries?
What emergency shutdown did you install by the meter? Was it wired into the solark to do the shutdown? Also, how did you power the tigo CCA -- guessing dedicated breaker in house elec panel, and not via sol-ark nor battery directly (via dc-dc converter)?
A beautiful installation. Congrats and thanks for sharing.

You are right it is but I guess the inspector let him do it.
Yeah pretty basic code stuff and really dumb thing to do
Unsafe working over batteries to access 15K. AHJ should be fired!

what do you think of the new EG4 18K with their PowerPro heated wall mounted batteries which integrate directly?

Yes, exactly.
will that sol ark start a 4 ton A/C condensing unit?
I actually haven’t tried it yet. We have an install coming up soon; I’ll give it a shot. I think you’ll need a soft start on the compressor.
@@mysolhome when it's all set up and done please post a video of that....I'm really interested in the results..... thanks
Yes you may need a micro air soft start
So, can you tell me how much these eFlex consume to run without any loads at all?
They don’t consume anything measurable. The inverter would have the standby losses without load.
How many panels did you use?
36
Looks great! What was the cost of a system like this?
Hi Matthew, right around 30k with the optimizers. Hope this helps.
You don’t need the communication for the battery and inverter just something extra
What emergency shutdown did you install by the meter? Was it wired into the solark to do the shutdown?
Also, how did you power the tigo CCA -- guessing dedicated breaker in house elec panel, and not via sol-ark nor battery directly (via dc-dc converter)?
Just a simple switch that is wired to the Sol-Ark RSD input. You are correct on the CCA wiring.

Neutral conductor should not be in a separate conduit. Heating effect!
