Solar Power Management Module for 6V-24V Solar Panel

This solar power management module is designed for 6V-24V solar panels. It can charge a 3.7V rechargeable 14500 Lithium-ion battery (battery not included) or other 3.7V Li-Ion batteries via the PH2.0 connector via a solar panel. The USB connection and pin headers provide a regulated 5V 1A output. The module features MPPT (Maximum Power Point Tracking) function and multi-protection circuits, making it able to keep working with high efficiency and stability. The module is suited for solar-powered, low-power IoT and other environmental protection projects. Please read the Product Wiki before using.
