Hey Josh, Good ideas as always. I'd really prefer to run AC off the batteries while on the hook. It doesn't run continuous all night, but cycles and most nights, I turn off the AC for the night after it's cooled down the cabin. Usually around 11pm. I would invest in Lithium to a point. Two lithium 200ah batteries weigh almost the same weight as two 100 Ah AGMs. tMy goal is to determine the best way to build a reliable system, identify all the components needed, price those and consider all the wiring issues. if it's too expensive, it will justify staying at a marina on hot nights, and plugging in. Chuck
