CN3791 12V MPPT Solar Charger Module

The CN3791 12V MPPT Solar Charger Module is an efficient and compact DC-DC solar charger designed to charge a single-cell 3.7V LiPo battery using maximum power point tracking (MPPT) technology. Utilizing the CN3791 IC, this module adjusts charging parameters dynamically to extract the most power from your solar panel under varying sunlight conditions, improving efficiency and charging speed significantly compared to linear chargers.

Setting up the module is simple – connect your solar panel (6V–17V input range) to the input JST PH2.0 connector and your LiPo battery to the output. The onboard MPPT controller ensures optimal conversion by keeping the product of output voltage and current at its maximum possible value. With four pre-installed JST connectors, integration into projects is plug-and-play.
