Description
The Solar Power Management Module is a versatile and reliable device designed to harness the power of the sun and convert it into usable energy. This module is specifically designed to work seamlessly with 6V~24V solar panels, it is capable of recharging its 3.7V rechargeable Li battery through a solar panel or USB connection, providing 5V/1A or 3.3V/1A regulated output.
This module features an advanced MPPT (Maximum Power Point Tracking) function that maximizes the efficiency of the solar panel and multi-protection circuits, ensuring high efficiency, stability, and safety.
It is suited for solar-powered, low-power IoT, and other environmental protection projects. The module includes an onboard MPPT SET switch for improved charging efficiency, onboard two power output interfaces: USB port for 5V output, pinheader for 3.3V or 5V output, onboard high capacity aluminum electrolytic capacitor and SMD ceramic capacitor for stable performance with reduced ripple, 14500 battery holder and PH2.0 battery connector, for connecting multi kinds of 3.7V rechargeable Li-battery, several LED indicators for monitoring the status of solar panel and battery, multi-protection circuits: over charge / over-discharge / reverse protection/overheat / over current, stable and safe to use.
