Power to the People

The Autonomous4X4 F350 now has the solar charging system sorted out. I have a single 120 watt solar panel mounted to a custom fabricated roof rack. When I mount the box, the panels will move to the roof of the camper. I have an additional 200 watts that will be added to the system.

My Odyssey group 65, AGM battery under the hood is charged by a Powermaster 200 amp alternator before it sends power back to the dual Odyssey group 31, AGM house batteries.

The heart of the system is the CTEK D250S dual charger. It acts as a battery isolator and solar charge controller. “The D250S automatically selects the best connected DC energy source (of 2) for the purpose and switches between these energy sources to achieve high efficiency multi-stage charging.”

Everything will change when the camper box is mounted but the system is up and running. Right now the house batteries are powering my Whynter 65 quart mobile fridge through an extension cord plugged into the Samlex 300 watt pure sine inverter. Cold beer in the desert at last!
