Includes Solar Power Manager 5V and Semi-Flexible Monocrystalline Solar Panel (5V 1A).

The DFRobot Solar Power Manager series are 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 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. The module can provide up to 900mA charging current to 3.7V Li battery with USB charger or solar panel. 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 for battery, solar panel and output, which greatly improves the stability and safety of your solar projects.
Check the brief specification for all Solar Power Manager Series Products.
Version History
V1.0: It is highly recommended to use a 3.7V lipo battery with protection circuits to improve battery safety.
V1.1(Newest): Battery (BAT IN) overcurrent and over-discharge protection is added to improve battery safety. It can be used for 3.7 lipo battery no matter it is packed with protection circuits or not.
