When you receive a solar panel, first check the surface for damage. Then put it under the sun outside, the light on the back lights up. The solar panel charging cable is connected to the controller and the two indicators on the controller illuminate. The battery cable is connected again and the ‘Charged' indicator light is off (this time the controller and solar panel are working properly). If the full indicator lights up, the battery is fully charged. 
 
 This product has the following characteristics:
 
1. Solar cells use thin film technology and it can work in any weather. So long as there is sunshine, the battery can be charged. 
2.Full-automatic Controller: complete protection of battery, short circuit protection, reverse protection, overload protection, under voltage protection, over charge protection to improve system efficiency and extend battery life . 
3. It's convenient to connect. There is no need to extend the line. And it works under the safe voltage of human body. 
4.The surface of the glass material is easy to clean. 

 Reminder: 

1.After connecting the wires, please separate the red and black clamps to avoid collision and result in short circuit. 
2. The more sunshine there is, the better the charging effect will be. 
3. If conditions permit, place solar panels directly into the sunlight to maximize efficiency. 
4.If the car is charged, do not use it when starting the car and driving to avoid the surge of the car engine may damaging the solar charger.
