DFRobot solar power manager 9 V / 12 V / 18 V

Solar panel energy management module. Powered by 9 V / 12 V / 18 V panels. It has a converter with 5 V / 1.5 A; 3.3 V / 1 A; 9 V, 12 V / 0.5 A outputs, so it can be used as a 3.7 V Li-Pol package charger or USB charger. The module also has a number of protections: against reverse polarity, too high temperature, short circuit.

Main features:

• MPPT constant voltage algorithm, increasing the efficiency of the solar panel
• Solar panel input voltage from 7 to 30 V
• Different charging modes: solar / AC adapter / USB charger (maximum current 2 A)
• Three individually controlled, adjustable ON / OFF power supply for low power applications
• Ceramic capacitors (MLCC), safe, stable, high quality
• Various protections
• USB connector with ESD
