Introduction

This solar power management module is designed for 6V~24V solar panels. It can charge the 3.7V rechargeable Li battery through the solar panel or USB connection and provides a 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.

SAFETY CAUTION

  • Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage if they're not properly recharged or used.
  • Do not reversely connect the polarities when recharging or discharging the battery. Do not use an inferior charger/charging panel to recharge the battery.
  • Do not mix use old batteries with new ones, avoid using batteries of different brands.
  • When buying a Lithium battery, should always make sure the battery specification is compatible with the expansion board. Choose batteries from the formal manufacturer, and ensure the batteries will work stably and safely by aging test.
  • Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reach their max cycle life, or work over two years, whichever comes first.
  • Should be placed carefully and properly, keep it away from inflammable and explosive articles, away from children, avoid any safety accident caused by careless storage.
  • DO NOT put any non-rechargeable battery, like dry cell, into the battery holder. Serious consequences including explosions may occur if you try to charge a non-rechargeable battery.

Features

  • 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: pin headers 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 / overheat / over current, stable and safe to use

Capacity indicators

Battery capacity LED1 LED2 LED3 LED4
 75~100% ON ON ON ON
50~75% ON ON ON OFF
 25~50% ON ON OFF OFF
 5~25% ON OFF OFF OFF
1~5% Flashing OFF OFF OFF
0% OFF OFF OFF OFF

How to use

  1. Turn the switch to ON and press the BOOT button. The LEDs will turn on and indicate the capacity.
  2. Connect the solar panel to DC-002 or the screw terminal with the adapter. If the connection is correct, the Solar Charger indicator turns on. If you reverse the connection, the Solar Warning indicator will turn on. The Solar Done indicator will turn on if the battery is fully charged and turns off the Solar Charge indicator.
  3. If you connect the power adapter to the TYPE-C interface, the Quick LED indicates the fast charge mode. The LED is off if your charger doesn't support a fast charge. The indicators of capacity flashing when charging and turn off when fully charging.
  4. The Type-C interface can only be used for discharging, you can connect it to power other USB devices.
  5. USB -OUT interface can be used for powering other USB devices.

Notices:

⚫BOOT button: single-click to enable 5V output, double-click to disable
⚫If the working current of the load is less than 40mA, the board goes into sleep mode and cut off the 5V output.
⚫The fast charge mode can only work if the power adapter supports fast charging.

Working with Raspberry Pi

This board can be used with Solar Powering Application for MCU and SBC like Raspberry Pi/ Jetson Nano / Arduino and so on.

If you need to chanage the input voltage of solar panel, you need to take apart the case and change the setting of DIP switch in PCBA, For example, if you want to change the voltage to 18V:
