The #offgrid solar was a $10,000 investment, a 10KW pallet of solar panels, a pair of lithium iron phosphate batteries for 10KW, and a 6KW solar inverter. I ordered from #SignatureSolar and they had the liftgate truck in my driveway the next day. It took me a few hours to snap everything together and 500 volts of current flowed into the solar inverter to charge the rack mount batteries and give me 240/120VAC. Everything is generic, highly redundant, and easily bypassed, repaired, or replaceable if something breaks. I had mounted a breaker box on the wall with outlets and a lot of DC converters directly to custom high power LED lighting for the rooms in the house. It is enough to charge the EV batteries too.
