Features Fully digital control technology, charging conversion efficiency up to 97%. Real-time recording function for power statistics. Innovative maximum power point tracking technology (MPPT) with maximum power point tracking efficiency >99%. The LCD screen dynamically displays the operating data and working status of the device. Four stage charging: MPPT, strong charge, balanced charge, trickle charge. External temperature sensor for more accurate temperature compensation. Built-in over-temperature protection mechanism, when the temperature exceeds the set value, the charging current decreases linearly with the temperature, reducing the temperature rise of the controller and avoiding damage to the controller caused by high temperatures. Automatic detection of the 12V/24V system voltage. Features: Four stage charging: MPPT, strong charge, balanced charge, trickle charge. Selection of battery type, working mode and protection method.
