Follow up question. If I were to purchase a hybrid inverter like the one below that outputs 230vac single phase would I be able to safely run an air conditioner designed for 220vac split phase? I'm not concerned about running any appliances other than the air conditioner...
Bit of a snag though. I just realized all 18000 BTU AC units are 220v in the US. Looks like I'm going to either have to go with a 12000 BTU unit or get an inverter that outputs 220v.
Inverter $520
Battery $750
Panels $450
BMS $140
Hardware and cables $200
$2060 for the entire system. I may upgrade the panels down the road, but these are so much cheaper than other panels I figure it's worth giving them a shot.
Good question. If not, I'm planning to throw a soft start module into the mix. https://www.microair.net/products/easystart-364-3-ton-single-phase-soft-starter-for-air-conditioners
Am I missing something or is this a stupid good deal? Buy 2 and get 6720 Wh for $1050?

Yeah, my SEER 10 comment was just to keep the math easy. :)
A newer 18000 BTU SEER 20 mini-spit would draw 900 Watts. Could the setup above indeed power such a unit? I'm skeptical since this seems like a relatively small investment to significantly reduce the power bill. Seems like more people...
I'm trying to determine the max size AC unit I could safely run with the following set up without constantly tripping the breaker. A 18,000 BTU, SEER 10 unit would presumably draw about 1,800 Watts. But that doesn't account for the surge when the compressor switches on - not sure how many watts...
