10A 12V/24V dual battery solar charge controller regulator motorhome camper boat

This is a perfect solar controller for a caravan, motorhome, camper, boat or another system with 2 independent batteries or battery banks (e.g. engine and leisure battery). You can set initial charging priority e.g. 80% of power to go to the engine battery and 20% to leisure battery. When one of the batteries is fully charged the controller will automatically divert full power to the other battery.

Can the unit work with only 1 battery? Yes, absolutely! The controller will determine automatically if there's only 1 battery connected and will pass 100% of charging current to this battery. You can add a second battery later.

This controller can work with solar panels with combined power up to 160W (12V) / 320W (24V).

It has many protection functions, such as stopping reverse current at night (from the battery back to the solar panel), over charge, short circuit, reverse polarity etc. Other features include various LED indicators, battery type selection (sealed, gel, flooded) and an RJ-45 socket for an LCD remote meter / display (sold separately). A built-in temperature sensor allows automatic adjustment of charging parameters depending on the ambient temperature.

A built-in temperature sensor allows the controller to optimise the charging process depending on the ambient temperature. If you are planning to position the controller far away from the battery, or if the battery and the controller are exposed to different ambient temperatures, an external remote temperature sensor with 3m cable is recommended for this dual battery solar charge controller. To enable connection to the screw terminals of the controller, the green connector block on the end of the remote temperature sensor cable should be unscrewed.
