Solarthon MPPT Solar Charge and Discharge Controller 20A/40A/60A
The Solarthon MPPT Solar Charge and Discharge Controller is an advanced charging method designed to maximize the power output of your solar panel system. With its maximum power point tracking (MPPT) technology, this controller can monitor the power generation voltage of your solar panel in real time and track the highest voltage and current values. This ensures that your battery is charged with the maximum power output, optimizing energy extraction from your solar array.
With the Solarthon MPPT Solar Charge and Discharge Controller, you don't need to worry about adjusting any settings. The maximum power point tracking mode is completely automatic, adapting to the changing environmental conditions to always find the optimal power point of your solar panel. This means you can enjoy the benefits of maximum energy extraction without any user intervention.
Choose from three different models: 20A, 40A, or 60A, depending on your specific power requirements. The Solarthon MPPT Solar Charge and Discharge Controller is manufactured by Guangdong Solarthon Technology Co., Ltd., a trusted company in the solar energy industry.
