25W Off-Grid Solar Lighting System with 4×5W LED Lights, 12V Battery & USB Output

This off-grid solar lighting system is designed for use in locations without access to mains electricity. It operates independently from the grid and generates power exclusively from solar energy. The system is suitable for sheds, garages, outbuildings, farms, stables, cabins, camping setups, travel use, and other outdoor or remote applications.

During daylight hours, the 25W solar panel charges the internal battery housed within the control unit. Stored energy is then used to power up to four 12V LED lights connected directly to the control unit. A USB output is also provided for charging mobile phones and other USB-powered devices.

The control unit includes a built-in rechargeable battery and an integrated solar charge controller that automatically manages the charging process and protects the battery from overcharging. Under suitable sunlight conditions, the battery can be fully charged within several hours and provides sufficient energy for extended lighting operation depending on load configuration.

The system is designed for simple installation and operation. The solar panel is supplied with a long connection cable, while each LED light includes its own cable and integrated On/Off switch. All components use pre-fitted connectors for quick plug-and-play installation.
