Compare brisk vs penguin 11 - Dometic Rooftop RV Air Conditioner

If your inverter puts out enough power, sure. It may drain your batteries pretty fast, though. Check the power rating of your AC and compare it to the power output of the inverter. Add a safe margin for everything else you want to run at the same time.

If no element installed and connected, heat setting will not work.
