House batteries (has 2) durning storage.

On our new 5er it has a battery disconnect switch but doesn't shut every thing off. Just had a RV carport built but to far away from ac power to plug in. So thinking maybe a solar charger to keep the batteries charged
plus the demand. Or another disconnect switch directly off the battery to totally disconnect them and maybe a small solar charger.I don't want to pull the batteries because I do check things every 3 or 4 weeks inside and out during storage just making sure there's no problems with anything. What do you do? Your thoughts?

    How far away from the nearest outlet IS it ?

    I suggest that a long extension cord and a small "Battery Tender", or equivalent, maintenance charger would be best. Probably would keep them charged OK if connected only a day or two a month.

    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.
