Model selection：

EPIPDB-COM 10A, 12/24V AUTO

Ideal for off-grid solar system up to 120W, 12V or 270W,24V

EPIPDB-COM 20A, 12/24V AUTO

Ideal for off-grid solar system up to 270W, 12V or 550W,24V

 

This 10A,20A dual battery solar charge controller is designed for independent charging of 2x12V or 2x24V batteries / battery banks. The controller uses PWM (Pulse Width Modulation) technology which increases charge acceptance and extends 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 2 independent batteries (e.g. engine and leisure battery). Initial charging priority can be set e.g. 80% of power 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.

The unit can also work with a single battery. If there's only 1 battery connected, the controller will automatically charge it at full power. Second battery can be added later.

This controller can work with solar panels with combined power up to 160W (12V) / 320W (24V). It has many protection functions, such as reverse current, over charge, short circuit, reverse polarity etc.Other features include LED indicators, battery type selection (sealed, gel, flooded), temperature sensor and RJ-45 socket for a remote LCD meter (purchased separately).
