Solar Energy Manager B
5V-24V Solar Power Management Module, with MPPT, Type C Power Adapter, 5V/3.1A Regulated Output

Product Overview
The Solar Energy Manager B is a solar power management module with fast charging functionality. It supports charging 3.7V 18650 lithium batteries via solar panel and USB interface, and provides 5V/3.1A regulated output (the Type-C port also supports output with various protocols like PD/QC/FCP/PE/SFCP). The module features MPPT (Maximum Power Point Tracking) and battery charge/discharge protection. MPPT automatically adjusts charging power based on input voltage for more efficient solar energy utilization. The protection circuit monitors battery voltage in real-time to prevent overcharging and over-discharging, protecting the battery and extending its lifespan. Due to its excellent stability and efficient charge/discharge management, it can be used in solar power generation, low-power IoT, environmental monitoring, power banks, and other green projects.
Product Features
- Supports MPPT tracking for enhanced solar conversion efficiency.
- Supports charging through solar panels, power adapters, and USB.
- Compatible with 5V-24V solar panels, connectable via DC-002 power jack.
- Onboard MPPT SET switch to adjust to a voltage near the input voltage, improving charging efficiency.
- Provides multiple output interfaces: USB A, and USB C (Both support fast charging).
- LED indicators for monitoring battery charge/discharge status.
- Supports simultaneous charging and discharging.
- Overcharge, over-discharge, reverse polarity, and overcurrent protection circuits ensure safe and stable operation.
