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.

Thanks Hedges! Great input!

I'm curious if it would be better to get 9 panels and go 3S3P. Maybe I need more headroom than 150 OCV with the Growatt?

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

I'm planning to run an auxiliary AC unit during peak sun. Any adjustments you would make to this setup? Have I missed anything?

Am I missing something or is this a stupid good deal? Buy 2 and get 6720 Wh for $1050? https://www.aliexpress.com/item/1005002101859137.html?spm=a2g0o.cart.0.0.52f33c00r9KsOt&mp=1

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...
