I like the solar charger idea. say a 100 watt panel should handle most if not all. monitor the voltage (battery) and if you see it start to drop go to 200 watts of panel but I think 100 will do it. DO not forget a good charge controller for a 100 watt panel you need a 10 amp controller minimum. I'd not go bigger than 20 amp for the controller or the loss in the box will be too great. MPPT is best.
Don't follow my example....... I was in a pinch for storage so I moved my Bluebird to a lot with no power. I knew I needed a battery maintainer but to get me by until I ordered one I connected a stray 80 watt panel directly to the batteries (3x group 31) with no charge controller.
I got away with it. I think that if it had not been November -December in the Seattle area I would have boiled three batteries... Shame on me for taking two months to get the correct maintainer....
