The charge controller is the heart of every solar system and connects the solar modules with the batteries. Using high-performance technology, solar controllers convert the voltage that fluctuates throughout the day into a load-based or optimized voltage for ideal and gentle battery charging.
Ultra-fast MPPT tracking
Especially under cloudy sky when light intensity is constantly changing, ultra-fast MPPT algorithm can improve energy harvesting by 30% compared to PWM charge controller and 10% compared to slower MPPT controller.

Intelligent battery management with the BatteryLife algorithm
The intelligent BatteryLife algorithm monitors the state of charge of the battery and slightly increases the threshold for switching off the load every day until a constant voltage is reached. From this point onwards, the threshold for switching off the load is set in such a way that a constant voltage is reached about once a week. Compared to traditional battery algorithms, the BatteryLife algorithm extends the life of your battery, which always switches between "partial charge" and "full charge" (due to low self-discharge).
Internal temperature sensor
A temperature measuring unit is installed inside the controller, with which constant and trickle charge voltages can be compensated for depending on the temperature. The full output current is guaranteed up to 40°C.
Automatic battery voltage detection
The MPPT 75/15 automatically adapts to 12V or 24V systems.
Three-stage charging: Instead of simply charging continuously to the charging voltage, an innovative stage system is used (constant current, constant voltage and trickle charging stages).
