Engine Battery charging
We use the two 12 Volt Engine Batteries for Hydraulic Leveling after we shut the engine off. To maintain a full charge on the batteries is a 50 Watt Solar Panel mounted on the roof.
A MorningStar SunGuard PWM Solar Controller is attached to the batteries. This small setup ensures the batteries are always fully charged when parked. After leveling the Motorhome is the small amount of energy used recharged to the batteries.
