20A Photonic Universe dual battery solar charge controller

This high quality, brand new 20A 12V/24V dual battery solar charge controller is designed to charge and protect two batteries simultaneously, with automatic cut off to prevent over-charging. The controller uses PWM (Pulse Width Modulation) technology which increases charge acceptance and prolongs the life of your batteries. PWM technology can also recover some lost battery capacity.

This is a perfect solar controller for a caravan, motorhome, boat or another system with two independent batteries or battery banks (e.g. engine and leisure battery). You can set the 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 one battery connected and will pass 100% of charging current to this battery. You can add a second battery later.

This powerful 20A controller can work with solar panels with combined power up to 320W (12V battery system) / 640W (24V battery system).

It has many protection functions, such as stopping reverse current at night (from the battery 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 optional 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.

Controller specifications:

  • Rated charge current 20A
  • Fully automated operation and auto 12/24V selection
  • 3 pairs of terminals (input, battery 1, battery 2)
