The Solarthon MPPT Solar Charge and Discharge Controller, developed by Guangdong Solarthon Technology Co., Ltd., is an advanced charging method that maximizes the power output of your solar panel system.
MPPT stands for maximum power point tracking, a feature that allows the controller to monitor the power generation voltage of the solar panel in real time. By tracking the highest voltage and current values, the controller ensures that your battery is charged with the maximum power output.
Unlike other controllers, the maximum power point tracking mode of this series of controllers is completely automatic and does not require any user adjustment. This means that as the maximum power point of the solar panel varies with environmental conditions, the controller will automatically track and extract the maximum energy from the solar array.
With the Solarthon MPPT Solar Charge and Discharge Controller, you can optimize the efficiency of your solar panel system and make the most out of your renewable energy source.
