I'm putting my RV in covered storage for about 3 weeks and it's not being charged (although the batteries were full when I put it in storage). The simple view of the component layout is attached. There's a battery disconnect which I've turned off, but the way things are wired the dc to dc charger is still hooked up along with the solar controller. The devices are tied to ground/negative Do you think I have to worry about any "leakage" of current back through these devices?
