DFRobot Solar Power Manager - Solar energy management module - 5V

The energy management module is a small,high-performance modulefor 5 Vsolar panels. It is equipped withthe MPPT (Maximum Power Point Tracking)algorithm- a constant voltage that maximizes panel performance. It can supply a charging currentof 900 mAtoa Li 3.7 V battery. It has ON/OFF control and protection function for the battery, photovoltaic cell and output, which significantly affects the stability and safety of projects. In combination with popular controllers from Arduino family allows to create a complete system powered by solar energy.
