Lensun® Dual Battery 20A 12/24V Solar Panel Regulator Charge Controller + LCD Display Remote MT-1


Designed to charge and protect 2 batteries simultaneously, having automatic cut off to prevent over-charging. 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 240W (12V) / 480W (24V).Protection: over charging, short-circuit, reverse polarity, revert current to PV. It 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.
