CN3791 6V MPPT Solar Charger Module

CN3791 MPPT Solar Charger Module – 12V to 3.7V LiPo Battery Charger (2A Max)

Detailed Description:
This MPPT Solar Charger Module uses advanced Maximum Power Point Tracking (MPPT) technology to maximize energy transfer from a solar panel to a single-cell LiPo battery. Powered by the CN3791 charging controller, the module intelligently adjusts to changes in light intensity, ensuring optimal power harvesting from your photovoltaic source.

Simply connect a solar panel to the input JST port, and a LiPo battery to the output, and the module handles the rest. Its high-frequency PWM switching (300kHz) and current capacity of up to 2A make it an excellent solution for efficient and safe solar charging in off-grid or portable applications.
