Thanks yes i power my home also im in Fl so we need alot of powerThat's a lot of solar Are you just powering the barn or are you feeding other buildings?
Yeah it gets hot in there lol good idea with the heatsinksLove the Fan on the 4 Midnite CCs BTW. I did something similar on my midnite on a much smaller scale. Single 4" PC Fan 3"s away and placed the CC on a large heat sink
Yeah it will lol. I was at about 19% of my power from the GEN over the last 4 yrs. Its only run one time since i added the 9 kw of pv.Fantastic- thanks for sharing pics, 140kwh would surely minimise generator runtime ?
I just added 9kw of gcl bifacial on the barn and now i just won a 2016 model s 85d at the auction to remove more battery module's from.

I built the cabinet to hold 28 tesla modules
Im off grid 24-7.Are u totally off grid 24/7 or are u grid support (not grid tied) with full readiness for the next hurricane black out. I'm more the latter
I completely agree with everything you mentioned. The case is 1/8" steel but that could be a big fire.I would suggest locating the batteries in their own bunker (fire pit) so if they do go up, you get to keep everything else.
Future building codes will probably require (non lead-acid) batteries to be a UL listed system (so you'll have a piece of paper to document you did everything correctly in the event it burns.) There is to be an exception for repurposed EV batteries if located 5' or more from the house.
UL listed batteries have been recalled after fires. So I would think it prudent to treat lithium batteries as something that can and will burn, have a plan to minimize the loss.
Thats why i did an east and west arrayI presume the ground mount array is facing South.
As you add more, consider SW and SE. They will make slightly less power due to longer path of light through the air, but they spread output over more hours and reduce peak power. That lets more strings, more watts of PV, fit on a given charger controller, and flattens production for less cycling of battery, more charge remaining late in the day, starts recharging earlier in the morning.
I figure I can over-panel about 50% that way without clipping production.
