SmartSolar MPPT 100/20 (12V/24V/48V) 20A
The SmartSolar MPPT 100/20 is a highly efficient and intelligent solar charge controller designed to charge and maintain 12V, 24V, or 48V lead-acid or LiFePO₄ batteries using 12V or 24V solar panels. Its ultra-fast MPPT controller, programmable battery management, and innovative tracking algorithms ensure maximum power output from your solar panels, even in cloudy conditions, with charging currents up to 20A.
The adaptive 3-stage battery charging—bulk, absorption, and float—charges your battery quickly and then maintains it in optimal condition. The charge algorithm can be selected from 8 pre-set profiles or fully programmed to suit your specific application. Additionally, Equalisation or BatteryLife modes can be enabled to extend battery lifespan.
A convenient DC load output port automatically disconnects connected devices at a pre-determined voltage to prevent over-discharge and battery damage. The controller can be configured and monitored via Bluetooth, allowing you to view real-time or historical solar and battery data from a smartphone, tablet, or computer.
Safety features include over-current, over-temperature, over-voltage, reverse battery or PV polarity, and output short circuit protection.
