INTRODUCTION

DFRobot is launching a brand new series - Sunflower, focusing on high-efficiency, small power solar energy management for IoT projects and renewable energy applications.

Solar Power Manager 5V is a small power and high-efficiency solar power management module designed for 5V solar panel. It features as MPPT (Maximum Power Point Tracking) function, maximizing the efficiency of the solar panel. Apart from serving as a solar charger, the module can provide up to 900mA charging current to 3.7V Li battery with USB charger. The ON/OFF controllable DC-DC converters with 5V 1A output satisfies the needs of various solar power projects and low-power applications. The module also employs various protection functions, such as battery/solar panel reverse connection protection, output over temperature and over current/short circuit protection, which greatly improves the stability and safety of the system. You can also implement a Battery Capacity Indicator to check the current battery charging condition.


NOTE: This board DOES NOT have over-discharge protection circuits, please use a 3.7V Lipo battery with protection circuits.
