20A dual battery solar charge controller / regulator for motorhome, caravan, boat or any system with two 12V / 24V batteries or battery banks

Designed to independently charge and protect 2 batteries or battery packs at the required priority (eg 80% / 20%)
You can also use a battery – the second battery can be added later Suitable for solar panels up to 320W (12V battery) or 640W (including 24V battery)
Including remote LCD instrument communication port (purchased separately) All types of batteries support: Sealed, gelled, submerged

This 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 recuperate some lost battery capacity.
This can be 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 also be set e.g. 80% of power to the engine battery and 20% to leisure battery. When one of the vital batteries is fully charged the controller will automatically divert all 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 also be added later.
This controller can work with solar panels with combined power up to 320W (12V) / 640W (24V). It has many protection functions, such as reverse current, over charge, short circuit, reverse polarity and the like. Other features include LED indicators, battery type selection (sealed, gel, flooded), temperature sensor and RJ-45 socket for a remote LCD meter (purchased one after the other).
