Talking about the maintenance problems of solar street lights when they fail

After a long time or due to various influences, the solar street lights will not light up. As a professional enterprise, when the street lights fail, which aspects should we check? Shanghai Changhui Lighting Technology Co., Ltd. produces solar street lights and solar garden lights all over the country. The following experts from Changhui Lighting will talk about how to repair the fault of solar street lights: (1) First check the indicator lights of the solar controller and battery Check if it is on, if not, check if the connecting wire between the controller and the battery is off. If the connecting wire is normal, use a multimeter to check the voltage of the battery. If the voltage of the battery is normal, it is the problem of the controller. , Replace a controller to see if the solar street light is used normally. (2) Then check whether the load indicator light of the controller is lit, and use a multimeter to detect whether it has output voltage. If there is no voltage output, replace the controller. (3) Finally, check whether the voltage of the LED driver input terminal is normal, and check whether the fuse of the LED driver is intact. If the fuse is good, use a multimeter to check whether the output voltage of the LED driver is normal. If it is normal , just change a LED lamp head, if it is not normal, then change a LED driver. Only when the root cause of the problem is really detected can the problem be truly solved. Therefore, I finally remind everyone not to blindly repair the solar street light components, which can only cause the opposite result.
