DFRobot Solar Power Manager V1.0 for 9V/12V/18V Solar Panel

The DFRobot Solar Power Manager series has been designed for IoT projects and renewable energy applications, providing secure and highly efficient embedded solar power management modules for manufacturers and application engineers. The Solar Power Manager is a complete low-power, high-efficiency solar power management module. It features an MPPT (Maximum Power Point Tracking) function that maximizes the efficiency of the solar panel. Additionally, it has three individually switchable DC/DC converters with outputs of 5V 1.5A, 3.3V 1A, and 9V/12V 0.5A. These features meet the requirements of various solar power projects and low-power applications. The module also includes several protection functions that safeguard against overheating and short circuits, significantly enhancing the system's safety.
