TROUBLE SHOOTING OF SOLAR LED STREET LIGHTING

Lamp does light up at all

Ambient light is much stronger

The light source will start automatically when the ambient light dims to a certain degree

Light source is damaged

Replace it with the same light source

The output circuit is open, short, or grounded

Check the output circuit connection

The connection between the storage battery's terminals is an open circuit

Check the connection between the storage battery's terminals and make sure it is okay.

The controller is damaged

Repair the controller or replace it with the same model controller.

Lamp works irregularly or shuts off too soon

The solar panel is covered by other things

Clean the solar panel.

The voltage of the storage battery is below 11.1V (22V for 24V system)

1. If the low voltage is caused by too many rainy days, it will recover automatically when the sun returns.

2. Check the connection of the solar panel

3. Check the battery connection
