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.


  • 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
  • Onboard high capacity aluminum electrolytic capacitor and SMD ceramic capacitor, reducing the ripple, stable performance
  • 14500 battery holder and PH2.0 battery connector, for connecting multi kinds of 3.7V rechargeable Li battery
  • Several LED indicators, for monitoring the status of solar panel and battery
  • Multi protection circuits: over charge / over discharge / reverse protection / over heat / over current, stable and safe to use


  • Solar panel input voltage (SOLAR IN): 6V~24V
  • Micro USB input voltage (USB IN): 5V
  • Pinheader / USB output (USB OUT): 5V 1A
  • Charging cutoff voltage: 4.2V±1Percent
  • Over discharging protection voltage: 2.9V±1Percent
  • Solar panel charge efficiency:: ~78Percent
  • USB charge efficiency:: ~82Percent
  • 7V battery boost output efficiency: ~86Percent
  • Max quiescent current: <2mA
  • Operating temperature: -40C~85C
  • Dimension: 65.2mm × 56.2mm × 22.9mm

    very good service

    I have bought many products from the evelta and have never been disappointed. They are very fast, thanks for your work.

    Original, Intact, With good packaging item sent

    Item is doing perfectly what it is supposed to do... Yes it does the work of an mppt. Max charge current is 500 ma... Which with even lesser sunlight easily achieves 450-470 ma. Brighter sunlight touches 550-570 ma. Output is rated 1 amp... But can output 2.2 amps... But heats rapidly above 1. 3 amp. I have attached a 9600 mah lithium ion battery, works perfectly. Recommended for everyone who wants to make small compact solar powered projects. Thank you Evelta for this beautiful hardware
