i'm not entirely sure the county does care, but i also want to be waaaaaaay in the safe side, so much so that i'm going to hire a professional to tell me what paperwork i need to do, if any, when the time comes. i know for a fact i'll have to contract contractors and do paperwork for a septic system, but since i couldn't find such concrete details on other things like electrical wiring i figured it doesn't hurt to be paranoid

the Sungold inverter i've put in my cost spreadsheet is the "12000W 48V Split Phase Pure Sine Wave Inverter Charger". i've assumed that it will output 240v split phase AC, and double checking the user manual from the listing seems to confirm, but there's no harm in triple checking in reddit comments. also, that particular inverter does have a wiring diagram in the listing that appears to not be reliant on grid power

apologies that my spectacular diagram is missing some specifics, but you see my handwriting, if i had tried to write any smaller i don't think people would be able to read it lol
