deal-breaker for me at this price point is no UL listed components for NEC residential install. i know SOK batteries are, so you would need to come up with something other than victron. sorry; but at that pricepoint i'm paying someone to install it/support and doing it legally.
i specd out a very similar system for a good friend using SolArk AiOs and made sure all was UL components so he could get it approved. $90k. he decided against it as it would be far cheaper for him to get a backup diesel generator and a few thousand gallons of fuel which would then allow him to install a much smaller PV array. being in Michigan, we get zero sun from November through February so he couldn't justify the cost. he said he's going hybrid wood boiler/diesel genset/PV for under $40k and thinks it's a better balanced setup for him as he has a diesel tractor he needs to power, anyway.
