Specification: Features: Innovative maximum power point tracking technology (MPPT) with maximum power point tracking efficiency >99%. Full digital control technology, charging conversion efficiency up to 97%. LCD screen dynamically displays the operating data and working status of the device. Automatic identification of 12V/24V system voltage. 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 temperature, thereby reducing the temperature rise of the controller and avoiding high temperature damage of the controller. Real-time electricity statistics recording function. Choice of battery type, working mode and protection method. Four-stage charging: MPPT, strong charge, balanced charge, float charge. 2 USB interface (EU series) current-limiting charging mode, when the solar panel power is too large, the charging current is greater than the rated current, the controller automatically reduces the charging power, and works at the rated charging current. Comprehensive electronic protection. Specification: 4000m Around oblique line value separately on behalf of 12V and 24V system's value.
