Controller Current: 100A Controller Voltage: 12V / 24V Automatic Identification Controller Standby Current:1 x Solar Panel 1 x Car Charger Connector 1 x Battery Clip Cable 4 x Suction Cup 1 x Solar Panel Manual 1 x Controller 1 x Controller Manual Solar panels considerations:1. When charging, make sure that the surface of the solar panel faces the sun.2. Avoid contact with impact objects and other acuminate objects.3. Do not bend the solar panel too much to avoid breaking.4. Keep the surface of the panel clean when charging to maintain the high efficiency of solar power generation. Controller considerations:1. Controller automatically recognizes 12V/24V. When installing for the first time, please make sure that the battery has enough voltage so that the controller can recognize the correct battery type. In order to protect the service life of the battery, once the battery voltage is lower than 8V, the solar controller will automatically shut down.2.
