I plane on buying one or two Battle Born Batteries.
Heres my question, If I run the AC during the heat of day will the 600w keep the battery(s) charged up for the evening to charge the little stuff.
We've built many systems for trailers. I've never found a 5000 BTU AC that only uses 450 Watts. They do cycle and typically run 30% of the time, depending on the temperature outside vs. inside.

Battleborn are very good batteries. But each 100AH battery holds 1200 Watt-Hours of energy.

600 Watts in the most ideal conditions in Souther California will produce about 3,600-4,000 Watt-Hours. While this is enough to recharge that two batteries, it isn't much.

A Typical layout for one of our Mi-Grid 500 systems was 2000 Watts of Solar with 6 x 1200 Watt LifePo4 batteries. We also included a 4000 Watt auto start generator which can recharge the batteries when they get low. This was connected to a 120VAC inverter system with 4000 Watt output.

The lowest power consumption AC units are inverter (variable speed)
