Solar Panel Power Controller

Solar-Solar Panel Power Controller

DFRobot Solar Panel Controller Series,, is designed for IoT projects and renewable energy projects, providing safe and highly efficient embedded solar energy management modules for manufacturers and application engineers.

Solar Panel Power Controller is a small power and high efficiency solar energy management module designed for 5V, 5V solar panels.

It functions as the MPPT (Maximum Power Point Tracking) function that maximizes the efficiency of the solar panel. The module can supply 900mA charging current to 3.7V Li battery by USB charger or solar panel. 5V 1A output ON / OFF controllable DC-DC converters meet the needs of various solar power projects and low power applications. The module also uses various protection functions for battery, solar panel and output, which greatly improves the stability and safety of your solar projects.
