This solar lighting system is ideal for places with no mains electricity such as outhouses, sheds, garages, farms, stables, as well as for camping, travel and any outdoor activities (e.g. a for a yurt). The system is fully independent from the grid and works purely based on sunlight energy or the power stored in the battery. During the daytime, the 100W solar panel charges a 12V battery inside the control unit, which then provides power to the 4 x 5W 12V LED lights connected via front sockets on the control unit. In addition, there is a standard 5V USB socket for charging mobile phones and USB compatible devices. The control unit has a built-in 18Ah Lithium battery with an automatic charge controller to manage the charging process and prevent overcharging. The solar input can take 18-25V DC power from any suitable solar panel and the battery can provide enough energy to power 4 LED lights continuously for 9-10 hours. The system is very convenient to use and 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 a quick "plug and play" installation.
