I believe a Dometic Penguin 11,000 BTU A/C only draws about 12 amps. Someone correct me if I'm wrong but you should be able to run your A/C on a 15A or better yet a 20A circuit. Just don't run any other major loads at the same time
. Make sure batteries are charged so the converter doesn't try to charge them. If one throws the battery isolation switch the power center can't charge it and the converter only outputs what is required to power a few other low draw items directly like LED lights.
