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. Key Features: MPPT technology for maximum solar energy utilization Built-in CN3791 Li-ion charging controller 2A maximum charging current Compact design with pre-soldered JST connectors Ideal for portable solar-powered systems Applications: Off-grid solar-powered electronics Outdoor IoT devices Remote sensor nodes Solar battery banks for DIY projects Educational and renewable energy applications Specifications: Model: CN3791 MPPT Solar Charger Input Voltage: Up to 18V (recommended 12V panel) Battery Support: Single-cell LiPo (3.7V nominal) Max Charging Current: 2A PWM Switching Frequency: 300kHz Connectors: 2-pin JST/PH2.0 (x4 installed) Charge Control: MPPT with automatic adjustment Dimensions: Compact size, easy to integrate Package Includes: 1 × CN3791 MPPT Solar Charger Module 1 × Pair of wires with 2-pin JST connectors
