To soak up the solar, four BattleBorn 100Ah Lithium batteries were installed under one of the dinette benches. It was a tight fit! Next, we installed a Magnum 2800w Pure Sine Wave inverter charger and an Outback MPPT solar charge controller. Last, we set the system up with a Magnum Advanced Remote Control and a battery shunt to monitor the status of the system. Customer was able to run the entire camper off battery power, including the roof A/C unit.
