Solar Energy Manager A
5V-24V Solar Power Management Module with MPPT, Type-C Power adapter, 5V/3.1A Regulated output, USB Charging Module
The Solar Energy Manager A is a solar power management module supporting charging of a 3.7V 18650 lithium battery via solar panels and USB. It offers a regulated 5V/3.1A output (with the Type-C port supporting multiple protocols such as PD/QC/FCP/PE/SFCP). The module includes MPPT (Maximum Power Point Tracking) and battery charge/discharge protection, which dynamically adjusts charging power based on input voltage, maximizing solar energy utilization. The charge/discharge protection circuit monitors battery voltage to prevent overcharging and over-discharging, ensuring battery safety and longevity. Its stability and efficient charge management make it suitable for solar power generation, low-power IoT, environmental monitoring, portable power banks, and other eco-friendly projects
