Our under installation solar system for our Montana

I have an identical solar/battery setup except I have 700 watts of solar and there is no way I could run my rooftop AC.

I'm lucky if I get 15 to 20 minutes on my 1,500 watt microwave without going into low voltage shutdown.

You may have the solar and battery guts to run it if you go by the specifications for the individual components but that low voltage (usually 11.5) shutdown of the inverter will bit you in the ass every time.
