This solar power management module is designed for 6 to 24V solar panels. It can charge the 3.7V LiPo battery via a solar panel or USB connection and provides a regulated 5V / 1A output.
The module has a maximum power point tracking (MPPT) function and multi-protection circuits, so it can still operate highly efficient, stable and safe. It is suitable for solar powered, low power IoT and other environmental protection projects.
