How to find out the cause of a failure of solar street lights

The operation of solar solar street light is actually very simple. To put it bluntly, it is just a process of charging and discharging. During the day, the solar panels will be continuously charged, and at night, the battery will continue to supply power to the lamp holder, which is repeated every day. This process continues to loop, but if the solar solar street light fails, such as the lighting time of the lamp suddenly becomes shorter, or the lamp does not light up, how should I find out the reason? 　　 It is necessary to find out whether the lamp is directly off , Or the lighting time of the lamp suddenly becomes shorter. If the lighting time of the lamp suddenly becomes shorter, it means that there is something wrong with the configuration of the lamp, or the power generation on the battery panel is not enough. The reason is probably because of the battery. A very thick layer of dust is attached to the board, or it may be caused by unreasonable configuration. For example, if there is a thick layer of dust on the battery board, it usually occurs in the riverside area. At this time, you only need to wipe the battery board. Just clean.　　 If the lamp does not light up, it may be that the battery is broken or the controller is broken. Generally, the battery board and the lamp holder are rarely damaged. Assuming that there is something wrong with the controller, the troubleshooting method that can be used is to first test the voltage of the battery and the battery panel with a voltmeter. If the solar solar street light battery panel is in an environment with sunlight during the day, the battery panel voltage is still at 12 volts. The above words. It means that there is no problem with the battery board. If the battery voltage remains above 10 volts, it means that the battery is also normal. Then you can consider changing to a new controller. It can be explained that there is a problem with the controller.　　Basically, it is very rare that the battery and the battery panel will not light up at the same time. Regardless of the situation, it is better for everyone to check more. If the problem is found, first consider replacing the controller of the solar street light, and then consider replacing the battery.
