Solar Power Manager (for 9V/12V/18V solar panel)
The DFRobot Solar Power Manager is a complete multifunction solar power management module designed for IoT and renewable energy projects. It integrates MPPT (Maximum Power Point Tracking) technology to maximize solar panel efficiency and supports multiple input sources including solar panels, USB chargers, and AC adapters.
This module is capable of delivering up to 2A charging current to a 3.7V lithium battery, while offering three regulated outputs at 5V 1.5A, 3.3V 1A, and 9V/12V 0.5A. Built-in comprehensive protections and independent ON/OFF control for each output make it ideal for low-power applications, solar-powered robotics, and environment monitoring systems.
