Chuck - do some research on lithium, they are way cheaper now than even a year or two ago. I’m in curacao at the moment refitting my new boat and am installing two 230ah LiFePo batteries. As others have said you need to determine the math regarding the ac. I’d strongly suggestadding a 3rd smaller agm as a start battery, setting up the switching appropriately, then using lithium batteries for the house. You’ll never look back. I documented this on the windstar blog and I think the switching/acr setup would work for you but you’d need to be sure of your real overnight load (fridge, anchor light, ac, Netflix?). And the recharge capacity of your charge sources.
