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

This solar power management module is designed for 6V to 24V solar panels. It can charge the 3.7V Li battery via a solar panel or a USB connection and provides a regulated 5V/1A USB output. This MPPT (Maximum Power Point Tracking) solar charger gives you the opportunity to get the maximum power from a solar panel into a LiPo battery. On the board is already a battery holder for 14500 batteries where you can directly insert a 14500 Lipo cell. However, you can also connect another Lipo battery via the PH2.0 connector. The Solar Lipo Power Management Module is suitable for solar-powered, power-saving IoT and other projects where you want to power your Arduino.

Attention:
DO NOT insert non-rechargeable batteries, such as dry batteries, into the battery compartment. If you try to charge a non-rechargeable battery, it can have serious consequences, including an explosion.

Features MPPT Solar Power Management:
