Professional MPPT controller designed for charging 12 / 24 V lead-acid and LiFePO4 batteries with solar energy. Compared to cheaper PWM type loss regulators, these regulators achieve much higher efficiency (up to 98%) and ensure maximum energy yield from solar panels. AGM, GEL and LiFePO4 sealed batteries are supported, the voltage is detected automatically. A comprehensive LCD display shows voltage of the solar panels and the battery, charging current, state of charge, load current, temperature or error code in case of a fault. At the same time, a thermocouple for charging temperature compensation is included. The connected DC load can be switched manually by the controller or simply programmed (e.g. twilight switching with a timer). A sophisticated protection system prevents the controller, solar panels and battery from damage or incorrect connection.
