OverviewThis solar power management module is designed for 6V~24V solar panel. It can charge the 3.7V Li battery through solar panel or USB connection, and provides 5V/1A regulated output. The module features MPPT (Maximum Power Point Tracking) function and multi protection circuits, therefore, it is able to keep working with high-efficiency, stability, and safety. It is suited for solar powered, low-power IoT, and other environmental protection projects. Features1. Supports MPPT (Maximum Power Point Tracking) function, maximizing the efficiency of the solar panel 2. Supports solar panel / USB connection battery charging 3. For 6V~24V solar panel, DC-002 jack input or screw terminal input 4. Onboard MPPT SET switch, select the level closed to input level to improve charging efficiency 5. Two 5V output interfaces: pinheaders and USB port 6. Onboard high capacity aluminum electrolytic capacitor and SMD ceramic capacitor, reducing the ripple, stable performance 7. 14500 battery holder and PH2.0 battery connector, for connecting multi kinds of 3.7V Li battery 8.
