Solar Power Manager 5V is a small and high-efficiency solar power management module designed for 5V solar panels.
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 a 3.7V Li battery with a USB charger or solar panel. The ON/OFF controllable DC-DC converters with 5V 1A output satisfy the needs of various solar power projects and low-power applications. The module also employs various protection functions for battery, solar panel, and output, greatly improving your solar projects' stability and safety.
