This kit includes Solar Power Manager (for 9V/12V/18V solar panel) and Solar Panel (9v 220mA).
The DFRobot Solar Power Manager series is designed for IoT projects and renewable energy projects, providing safe and high-efficiency embedded solar power management modules for makers and application engineers.
Solar Power Manager is complete small power and high-efficiency solar power management module. 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 2A charging current to 3.7V Li battery with AC adapter (within 30V) or USB charger, three individual ON/OFF controllable DC-DC converters with 5V 1.5A, 3.3V 1A, and 9V/12V 0.5A outputs. These features satisfy the needs of various solar power projects and low-power applications. The module also employs various protect functions, such as Li-battery protection, 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.
