CN3791 MPPT Solar Panel Regulator Controller - 12V

Overview:

The CN3791 Maximum Power Point Tracking (MPPT) is a solar charger for single-cell LiPo batteries. The charger gets the most possible power from a solar panel or other photovoltaic device and feeds into a rechargeable LiPo battery. Charging is made simple by plugging the solar panel into one side of the charger and the battery into the other. MPPT ensures that as the light intensity changes, the photovoltaic cells output is at maximum power, to make full use of solar energy. Each Solar Charger comes equipped with a CN3791 power tracking battery charging circuit and pre-installed four 2-pin JST/PH2.0 connectors.
