Solar panels to charge battery

Is it possible to charge the house batteries with solar panels when mh is not being used for a few months? I'm not able to keep mh at my home and storage location doesn't have electricity. As always advice is appreciated.
  • Same situation...

    Had battery problems,so installed a battery switch. Better, but still an issue.

    Installed a Renogy RV Solar "System" (one 100 watt panel, controller, etc.) and my batteries are now at 100% all the time.

    When we boondock, even in the cold with the furnace running all the time, the batteries are at 100% by about 10 AM. If its a cludy day , it might take till noon!

    You need both actually.

    Depending on the specific situation, it might be easier to remove the batteries and put them on a tender at home.

    And yes it's been discussed in earlier threads a LOT already. Please look.

    Either way, you should visit the RV at least once a month to inspect for unexpected water leakage, rodent infiltration, etc......and check the charge on the batteries if you go the solar route.
  • 100 watts should do it while in storage with everything off.
    Need a controller also.

  • Yes, it is more than possible. How big a panel depends on how big your batteries are and what the phantom load on them is.

    If you aren't using it for just a couple or three months, fully charge the house batteries then disconnect the negative cable. I left my van almost 6 months that way and it started first try.
