Install and set up the solar led street light and put it into normal use for a period of time, but suddenly it does not light up at night. We need to check the response of the controller indicator first, and check the controller indicator status to confirm the problem. If it is not lit, the controller may be damaged, or the system may be impacted by strong currents, such as being directly struck by lightning or short-circuit problems.

　 One, the light source is damaged

　　Due to possible natural or man-made reasons, the light source is damaged, causing the solar street light system to fail to work, not to light up at times, and to flicker.

　　Solution: repair the light source or replace the light source.

　　 2. The solar panel is damaged

Connect a multimeter to test the voltage of the solar panel without any load. Normally, the working voltage of the system is 12v, which will be higher than 12v under normal conditions. The battery can be charged only when the voltage is higher than 12V, if it is lower than 12V Then the battery cannot be charged. The solar street light system cannot work or the working time is not enough.

　　Solution: Replace solar panels.

　　3, the positive and negative poles of the solar panel are reversed

　　The solar led street light system only lights up once after installation. When the battery is exhausted, the solar led street light will never light up again.

　　Solution: Change the positive and negative poles of the solar panel.

　　4, the battery is damaged

Connect a multimeter to test the voltage of the battery without any load. Normally, the working voltage of the system is 12.8v, which will be higher than 12.8v under normal conditions. If it is lower than 12.8V, it means that the battery is fed and cannot be discharged. Solar street light The system is not working or working time is not enough. At this time, we need to use a charger to charge the battery. If the battery cannot be charged, we need to replace the battery with a new one.

　　The above are the four major factors and treatment methods for solar LED street lights not to light up. In order to ensure the normal operation of solar street lights, regular maintenance and inspections for professional LED solar street light manufacturers are essential.
