DFRobot Sunflower is a new series focusing on high-efficiency small power solar energy harvesting and management for makers, low-power applications and IoT projects. Solar Power Manager 5V is a small power and high-efficiency solar power management module designed for 5V solar panel (SE800826). 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.
