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

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...

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