Solar Power Management Module 6V~24V For Solar Panels and IoT Devices
The Solar Power Management Module is a versatile and reliable device designed to harness solar energy for low-power IoT and environmental projects. Compatible with 6V~24V solar panels, it can recharge a 3.7V Li battery via solar panel or USB, providing regulated 5V/1A or 3.3V/1A output. The module features MPPT (Maximum Power Point Tracking) technology for optimal solar efficiency, multi-protection circuits for safety, and onboard indicators for real-time monitoring.
Package Includes:
- 1 x Solar Power Manager
Note: 14500 battery is not included.
Features:
- Advanced MPPT technology for optimal solar panel efficiency
- Dual charging options: solar panel or USB
- Compatible with solar panels 6V-24V via DC-002 jack or screw terminal
