For winterization, should the 4 house batteries be disconnected from each other or can you just disconnect a lead at the inverter switch? Does anybody leave house batteries connected and solar power trickle charging over winter? With shrink wrap can’t be much of a charge but better than nothing?
Thanks in advance.
 
Tim - we disconnect the negative leads from our batteries and leave them in the boat for the winter here in Anchorage AK. Voltage was 12.7 in Sept and 12.55 in April.
 
We lay a heating pad set on low on top of batteries for the winter.
