Product Description:
The solar charge controller is the most important component of almost all solar systems that utilize rechargeable batteries. It is the heart of the system and regulates the power from the solar panel to the battery.
MPPT is the best type of solar charge controller to help you get the most out of your solar panels and significantly extend battery life. Since MPPT charge controllers are more efficient than traditional PWM solar charge controllers, they are widely used in most solar off-grid systems and RV solar systems.
