# of watts solar system needed to MAINTAIN coach batteries?

Class A with 2 12 volt coach batteries. Want to maintain while not in use.

100 watts if you don't disconnect, much less if you do.

You're talking just a solar float charger, right? Just to keep them fresh during the winter?

From what I read on Amazon this morning, 5-8 watts is working for other people.

I would also recommend 100 watts of solar and a dual bank controller. That would maintain both the house and chassis batteries quite easily.

Our coach has 4ea 6v deep cycle batteries and we have a 100w solar panel with controller which more than adequately maintains both coach & chassis batteries.
