The Solarthon MPPT Solar Charge and Discharge Controller, developed by Guangdong Solarthon Technology Co., Ltd., is an advanced charging method designed to optimize the power generation of solar panels.
MPPT, which stands for maximum power point tracking, allows the controller to monitor the real-time power generation voltage of the solar panel. By tracking the highest voltage and current values, the system can charge the battery with maximum power output.
This series of controllers features a fully automatic maximum power point tracking mode, eliminating the need for user adjustment. As the maximum power point of the solar panel varies with environmental conditions, the controller automatically tracks and adjusts to ensure maximum energy extraction from the solar array.
Key Features:
With the Solarthon MPPT Solar Charge and Discharge Controller, you can maximize the energy extraction from your solar array, ensuring efficient and effective power generation.
