The mini splits are coming,
Hi, This would make solar powered air conditioning a lot easier. https://www.youtube.com/watch?v=OmOkQerIITk Mini Split 460 watts maximum.

I'd just go for a rooftop unit with the SEER of the mini split. Current rooftop units are way behind home S&B systems in terms of SER. a typical rooftop 13.5K BTU unit has a SEER of about 10. (BTU out/watts in).
A SEER 20 similar to a mini split would drop the power by 2x, down to about 700watts, along with a decent LRA spec of 20A or so and bingo, easy to run the AC from a 2000W inverter generator with power to spare, easy to start with a 1000VAish inverter, ability to run for a reasonable amount of time from a reasonable sized battery bank and bigger rooftop or portable solar system.
I always thought SEER rating was kinda goofy. A resistance heating element has a SEER of 3.5. IMHO a better rating would be BTUout/BTU in. Then a resistance heating element would have a SEER of 1, a SEER of 3 would be 3BTU out for every BTUin. A better measure of unit efficiency.
