DFRobot's Solar Power Manager series is tailor-made for IoT and renewable energy projects. It offers secure and high-efficiency embedded solar power management modules to cater to the needs of makers and application engineers.

One such product is the Solar Power Manager 5V, which is a compact and high-performance solar power management module designed specifically for 5V solar panels. It incorporates an MPPT (Maximum Power Point Tracking) function, which maximizes the solar panel's efficiency. The module can deliver a charging current of up to 900mA to a 3.7V Li battery through a USB charger or a solar panel.

Moreover, the DC-DC converters with 5V 1A output can be controlled ON/OFF, making it a versatile choice for various solar power projects and low-power applications. The module is also equipped with various protection functions for the battery, solar panel, and output, which ensures the stability and safety of your solar projects.

V1.1(Newest): Battery (BAT IN) overcurrent and overdischarge protection is added to improve battery safety. It can be use for 3.7 lipo battery no matter it is packed with protection circuits or not.

  • Constant voltage MPPT algorithm, maximizing solar panel efficiency
