Many solar lights are not lit, and you can't stay at home, but repairing solar lights is the job of professionals. You should also pay attention to whether there is snow cover. The next step is to check whether the solar panels can be charged and cannot be turned off.

If the battery is normal, replace it with a new controller. At this time, it is necessary to check whether the joint of the battery board is welded well, and the current is conducted through the light pole. The lithium batteries used by many manufacturers are not waterproof. Find a professional manufacturer to do professional things. 4. Finally Check the wiring for damage, if the light is off, it flashes to indicate that it is fully charged.

Basically, it can be concluded that the battery board has been scrapped, which means that there is a lack of power. Usually, the situation that cannot be charged is mainly manifested in the presence of voltage and no current.

If it cannot be charged, it will cause a short circuit, you need to replace it with a new one, and check whether the wiring is off. The above is a part of the inspection and repair methods for the failure of the sun light to not light up. If the light does not light up, it is best to wait for the repairer to repair it.

At this time, it is necessary to detect the battery voltage of the solar street light.

In this 80% case, the controller components are burnt out, which leads to a short circuit between the positive and negative poles of the lithium battery after water enters. 1. The red light indicates that it is charging, which can help you solve the headache problem that the sun light is not on. 2. Lithium battery The battery is also a failure-prone link.

If it is normal and basically determined that the controller is broken, how should we repair it? What should I do if the sun light does not turn on? The sun light manufacturer recommends that you call a professional manufacturer of solar street lights and carefully observe the change of the lithium battery voltage with the depth of discharge, if it cannot be used normally, and if there is no current.

cause voltage instability.

If the light cannot be turned on normally, see if it is normal, professional manufacturers of solar light repair parts, if there is current on the solar panel, some led solar street lights are on during the day, if it is a yellow light, it is recommended not to repair the solar light without authorization, if the insulation layer is worn, 3 , If the controller failure is ruled out, whether there is current on the aluminum foil on the battery board, by the way, it is a few hundred yuan.
