This solar power management module is designed for 6V~24V solar panel. It can charge the 3.7V rechargeable Li battery through solar panel or USB connection, and provides 5V/1A regulated output.

The module features MPPT (Maximum Power Point Tracking) function and multi protection circuits, therefore, it is able to keep working with high-efficiency, stability, and safety. It is suited for solar powered, low-power IoT, and other environmental protection projects.

Application Example

NOTES

  • CAUTION: DO NOT put any non-rechargeable battery, like dry cell, into the battery holder. Serious consequences including explosion may occur if you try to charge a non-rechargeable battery.
  • The 14500 battery is NOT included.

What's on Board

  1. Solar panel charging input: charged by solar panel, DC-002 jack or screw terminal
  2. USB charging input: charged by USB connection, connect a 5V power adapter through the Micro USB port
  3. 5V/1A power output: provides regulated 5V/1A output, USB port or 2.54mm pinheader
  4. Battery interfaces: for connecting 3.7V rechargeable Li battery, PH2.0 connector or 14500 battery holder
  5. CS8501: USB power management chip, for USB charging and 5V/1A boost output
  6. CN3791: solar power management chip, for solar panel charging and buck input
  7. Li battery protection chip: Li battery over charge / over discharge protection
  8. Battery switch
  9. MPPTSET switch (bottom side):
    supported level: 6V/9V/12V/18V/24V
    select the level closed to input level to improve charging efficiency
  10. BOOT key
  11. Battery capacity indicators
  12. USB charging indicators:
    USB Charge: on when USB charging
    USB Done: on when the battery is full charged by USB
  13. Solar panel charging indicators:
    Solar Charge: on when solar panel charging
    Solar Done: on when the battery is full charged by solar panel
    Solar Warning: on when solar panel reverse connection
  14. Battery warning: on when battery reverse connection
  15. Power output indicator: 5V/1A output
  • Supports MPPT (Maximum Power Point Tracking) function, maximizing the efficiency of the solar panel
  • Supports solar panel / USB connection battery charging
  • For 6V~24V solar panel, DC-002 jack input or screw terminal input
  • Onboard MPPT SET switch, select the level closed to input level to improve charging efficiency
  • Two 5V output interfaces: pinheaders and USB port
