Anybody have recommendations for a solar charger to keep my house battery charged during winter storage?
I'll be in a spot where they won't let me leave shore power connected to the boat. I don't want to disconnect the house battery, because then I'd have to manually close and open the engine hatch every time. And I can't leave the battery connected because parasitic loads would drain it within a week.
My plan is to disconnect the starter batteries, and use a solar charger for the house bank. I'm going to measure the parasitic load (current used by GPS receivers and other devices when everything else is turned off). That will tell me what size panel to get, and whether I need a regulator.
