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.

The Solar Power Manager 5V is a small power and high-efficiency solar power management module designed for 5V solar panels. It features an 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 batteries with a USB charger or solar panel.

The ON/OFF controllable DC-DC converters with a 5V 1A output satisfy the needs of various solar power projects and low-power applications. The module also employs various protection functions for the battery, solar panel and output, which greatly improves the stability and safety of your solar projects.

Solar panel not included - this panel is the perfect match.
