This is the ideal device for managing charging from multiple sources. It's really designed for managing solar + alternator power inputs, charging an auxiliary (house) battery system. The system will preference solar, providing lower loads on your engine when solar is available. With automatic ignition detection enabled, the system will isolate the starting battery when the engine is off, preventing discharge of your critical starting battery. It's fully automatic, with a set-and-forget type operation. A remote LED indicator module is included to provide in-car feedback of the system's status. Heavy duty screw down terminals are provided for power connections. Works with Lead acid, AGM, Calcium, GEL and LiFePO4 batteries (selectable), and accepts solar input of up to 30V open circuit voltage.
