Product description
MPPT charging module based on the CN3791 for charging 3.6/3.7 V Li-Ion and Li-Po batteries from a solar panel. A solution for powering electronics using solar energy. The battery acts as an energy storage device and continues to power your project even when the sun is not shining, while charging whenever solar energy is available. The module is safe and reliable, featuring integrated charging algorithms that provide precise control, high efficiency, and battery protection. The CN3791 uses Maximum Power Point Tracking (MPPT) technology to maximize energy extraction from the solar panel and charges the battery using Constant Current (CC) and Constant Voltage (CV) charging methods. It is suitable for solar-powered IoT devices, data loggers, sensor nodes, and other battery-powered projects requiring efficient solar charging.
The board is equipped with quick-connect spring terminals for connecting the solar panel and battery, as well as a JST connector for a Li-Ion/Li-Po battery. The module is designed for easy integration into solar-powered systems and uses the CN3791 charging algorithm for safe and efficient battery charging.
