Wave Solar Power Management Board

The Wave Solar Power Management Board is a versatile module designed to efficiently manage power from 6V–24V solar panels or Type-C power sources. It charges 3.7V rechargeable Li-ion batteries (not included) and provides a reliable 5V/3A regulated output. Supporting multiple fast-charging protocols such as PD, QC, FCP, PE, and SFCP, it is ideal for low-power IoT projects and environmentally conscious applications.



This module features MPPT (Maximum Power Point Tracking) technology to maximize solar panel efficiency and includes comprehensive protection circuits, ensuring safe operation against overcharge, over-discharge, reverse polarity, overheating, and overcurrent. Compact and efficient, it’s perfect for sustainable, solar-powered systems.

Board Layout

1. Solar panel charging input: charged by solar panel via DC-002 jack or screw terminal, self-adaptive input voltage
2. Type-C charging input: charged by 5V power adapter via Type C connector, or outputs 5V for external device
3. Power output: screw terminal: 5V/3A output
4. Battery interfaces: for connecting 3.7V rechargeable Li battery via screw terminal or PH2.0 4P connector
5. SW6106: USB power management chip, for USB charging and 5V/3A boost output
6. CN3791: solar power management chip, for solar panel charging and buck input
7. XB8886A: Li battery over-charge / over-discharge protection
8. Battery capacity indicators: lights up when charging or under load connection, and will turn off after 30s when there is no load connected
9. Solar panel charging indicators:
• Charge: on when solar panel charging
• Done: on when the battery is full charged by solar panel
