A highly efficient and intelligent solar charge controller designed to charge and maintain 12V, 24V or 48V lead-acid or LiFeP04 batteries from 12/24/48V solar panels. Thanks to its ultra-fast MPPT controller, programmable battery management and innovative tracking algorithms, the charger gets the most out of your solar panels, even during cloudy weather, with charging currents up to 15A. The adaptive 3-stage battery charging includes bulk, absorption and float to charge your battery as quickly as possible and then keep the battery in optimum condition. The charge algorithm can be changed to 8 pre-set algorithms or fully programmed to suit your application. In addition, equalisation or BatteryLife modes can be enabled to maximise the life of your battery. A handy DC load output port automatically disconnects any connected devices at a predetermined voltage to avoid over-discharging and possibly damaging your battery. Configure and monitor the solar charger and view real-time or historical solar and battery data from your Bluetooth® enabled Smartphone, tablet or computer. Safety features include over-current, over-temperature, over-voltage, reverse battery or PV polarity, and output short circuit protection.
