🌟 Product Overview & Key Features

This MPPT Solar Power Management Module is the ideal solution for powering your solar, low-power IoT, and green energy projects. Designed for 6V to 24V solar panels, it efficiently charges a 3.7V rechargeable Lithium battery while providing a stable 5V/1A regulated output for your microcontrollers (like Arduino) and devices.

  • Maximum Power Point Tracking (MPPT): Features an advanced MPPT function to maximize the solar panel's conversion efficiency, ensuring optimal power capture regardless of light conditions.
  • Dual-Source Charging: Supports charging the 3.7V Li-ion battery via a wide range of 6V~24V Solar Panels (using DC-002 jack or screw terminals) or a 5V Micro USB connection.
  • Stable 5V/1A Output: Provides a reliable 5V/1A regulated output through both a standard USB-A port and 2.54mm pinheaders, making it easy to connect external devices.
  • Adjustable Efficiency: An onboard MPPT SET switch allows you to select the voltage level closest to your solar panel's input (6V/9V/12V/18V/24V) for the highest charging efficiency.
  • Comprehensive Protection: Equipped with multiple safety circuits, including Over Charge, Over Discharge, Reverse Protection, Over Temperature, and Over Current circuits, ensuring stable and safe operation.
  • Flexible Battery Interface: Includes both a 14500 battery holder and a PH2.0 connector for connecting various types of 3.7V rechargeable Li batteries.

⚠️ Safety Caution

DO NOT put any non-rechargeable battery, such as a dry cell, into the battery holder. Serious consequences, including explosion, may occur if you attempt to charge a non-rechargeable battery.
