Off-Grid Solar Lighting System with 50W solar panel, 4 LED Lights, Solar Charge Controller and Lithium Battery

This solar lighting system is perfect for areas without access to mains electricity, such as sheds, garages, farms, and stables, as well as for outdoor activities like camping or for yurts. The system operates independently of the grid, relying solely on solar energy or the stored power in the battery.

During the day, the 50W solar panel charges a 12V battery located inside the control unit, which then provides power to 4 x 5W 12V LED lights connected via front sockets on the control unit. Additionally, there is a standard 5V USB socket for charging mobile phones and USB-compatible devices (adaptors for USB-compatible mobile phones are included).

The control unit comes with a built-in 18Ah Lithium battery that has an automatic solar charge controller to manage the charging process and prevent overcharging. The solar input can take 18-25V DC power from any suitable solar panel, or it can be charged from the mains using the SL-CH-3A mains adapter. The battery can provide enough energy to power 4 LED lights continuously for 9-10 hours, or twice as long if only two LED lights are connected.

The system is very user-friendly and easy to install. The solar panel adapter cable has two standard MC4 connectors for secure connection with the panel output, and each LED light comes with a 5m cable with an On/Off switch. All cables come with connectors for quick "plug and play" installation.

This product is covered by a 1 year manufacturer warranty.

In addition, solar cells are guaranteed to produce at least 90% of nominal power in 10 years after purchase and at least 80% of nominal power in 25 years after purchase. This warranty is provided by the manufacturer of solar cells.

Installation is very easy: the solar panel or mains adaptor should be connected to the charging socket at the front side of the control box via the correct adaptor wire (included), and 4 x LED light cables should be connected to the front 12V sockets. Then you should turn the control unit switch to ON and the battery will begin charging. Each LED light comes with a separate On/Off switch for your convenience.
