In this video we swap out our 30A Dual Input DC to DC Charger for a 50A to increase the charging capacity of our off-grid RV solar powered system.
What is a Dual Input DC to DC Battery Charger and how can it help your off-grid solar installation in your van, or RV? These battery chargers can take either an engine charge or solar panel charge and safely recharge the off-grid batteries that power your life. If you have an engine, this is a great way to effectively charge while driving.
We use ours to recharge the small 50Ah Lithium Iron Phosphate battery that runs our 12V ICECO refrigerator in the back of our towing truck.
