If we connect in parallel we could have two 12 volt 400 amp hour batteries giving us 800 amp hours but keeping our 12 volt system. We need 768 amp hours for our 12 volt solar installation. In the first step you are going to wire the battery to a charge controller. Connect battery to charge controller.

Always connect the rv house battery bank to the first battery position as it will receive the full charge before the second battery begins to charge. Solar charge controller keeps the solar panel from over charging your battery or batteries. They are usually wired in parallel to preserve the voltage of each panel but you can also wire sets of them together in series to increase the voltage to conform to the voltage of the battery bank if need be.
