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 panel2. Supports solar panel / USB connection battery charging3. For 6V~24V solar panel, DC-002 jack input or screw terminal input4. Onboard MPPT SET switch, select the level closed to input level to improve charging efficiency5. Two 5V output interfaces: pinheaders and USB port6. Onboard high capacity aluminum electrolytic capacitor and SMD ceramic capacitor, reducing the ripple, stable performance7. 14500 battery holder and PH2.0 battery connector, for connecting multi kinds of 3.7V Li battery8. Several LED indicators, for monitoring the status of solar panel and battery9.
