Модуль управления солнечной энергией 6 В ~ 24 солнечная панель поддерживает функцию MPPT USB соединение зарядка аккумулятора печатная плата на заказ

Overview

This solar power management module is designed for 6V~24V solar panel. It can charge the 3.7V 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.

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: 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 Li battery


• Several LED indicators, for monitoring the status of solar panel and battery
