Features Peak Tracking: Using advanced dual or multi peak tracking technology, when the battery panel is shaded or partially damaged, multiple peaks will appear on the IV curve, the controller can still accurately track the maximum power point. High Efficiency: Built in maximum power tracking algorithm, the MPPT tracking efficiency can be up to 99%, significantly improving the energy utilization efficiency of photovoltaic system, about 25% higher than PWM charging efficiency. Current Limit Charging: The Solar Charge Controller Support sealed liquid rich gel and lithium battery, with current limiting charging mode. When the charging current of the panel is greater than the rated current, the controller automatically reduces the charging power. Multiple Functions: The Panel Controller Supports instantaneous high current starting of capacitive loads, automatic identification of battery voltage, with lithium battery 0V charging function, and fault LCD display, convenient for users to determine system faults. Temp Rise Protection: Built in over temperature protection mechanism, when the temperature exceeds the device setting value, the charging current linearly decreases with the temperature, reducing the temperature rise of the controller. Feature: 1. Temp Compensation: The solar charging controller has temperature compensation function, automatically adjusts charging and discharging parameters, improves battery service life, and has complete electronic protection function.
