What is the reason why the Solar Light does not turn on?
There are usually 4 reasons why the whole Solar Light does not turn on. The common one is that the controller in the light pole has entered water and a short circuit occurs. First of all, you can check whether there is water rust on the terminal of the controller.

If this happens, it is most likely that the controller is damaged due to water ingress. You can use a multimeter to measure the organization of the two ends of the loop. If the resistance is too small, it will generally be a short circuit. At this time, you need to replace the controller.

If the controller is not damaged and short-circuited, and then see if there is a problem with the battery, you can use the battery voltage to measure it. If the battery does not store electricity, it will naturally need to be replaced in time.

If there is no problem with the battery, you can further check whether there is a problem with the solar panel, and whether there is voltage and current output under normal working conditions. If not, the battery panel needs to be replaced.
