I have a 31L with a/c.
Running a/c from battery / inverter is not practical.....would need v large battery bank and inverter would be much bigger than needed for anything else to take care of starting current.
I have a 2500 w inverter takes care of everything but a/c nicely.
I also have a honda 2000 generator but this will not take a/c starting current comfortably.
You can get a soft starter to make the a/c runnable from this size genny, but my choice is just to use the a/c when tied up to shore power. I like the genny just in case I end up offshore with flat batteries
