Features: The solar power management module Dtype is specifically for 6V~24V solared panel, supporting adaptived input through DC002 or screw terminals, multiple LED indicators for input antireverse protections 3.7V rechargeable lithiums batteries can charge through solared panel or typeC connectors, and provide 5V/3A adjust output (supporting multiple protocols such asPD/SFCP) This module have Power Point Trackings function and multiple protections circuit, so it can maintain efficient, stable, and safe operation. Used to monitor the status of solared panel and batteries, suitable for solar low-power Internets of Things, and other environmental projects. Supports Most Power Point Trackings function maximizes the efficiency of solared panel. Supports solared panel Multiple protections circuits: overcharge/over discharge/overheating/overcurrent, stable and safe to useNote:Excluding for RPi4b and Solared Panel;Excluding 18650 batteries. Specifications: For 6V~24V Solared Panel Dtype Supports Solar panel / TypeC power Adapters Provides: 5V/3A Regulated Output (Supports multiple protocols such asPD/SFCP) Types: Single Board/Single Board + Battery Case Note: Due to the problem of lighting effects and shooting angle, there is certain tolerances in the product, please understand. Please allow 0-1cm error due to the manual measurment. Package includes: 1Set Solar Power Management Board
