Many people know that the battery is a link that solar street lights are prone to failure. The batteries used by many manufacturers are not waterproof, which leads to short-circuiting of the positive and negative electrodes of the battery after water enters, resulting in unstable voltage. Next, Wholesale Solar Garden Lights Manufacturers teaches you how to troubleshoot street lights?
1. Detect the solar street light controller, which is the core of the solar street light. The red light means charging, flashing means the battery is fully charged, if it’s yellow, it means the battery is in short supply and the light cannot be turned on normally. At this time, the battery voltage of the solar street light needs to be checked. If it is normal, it is determined that the controller is broken. If the light is off, check whether the wiring is off.
2. If the controller failure is ruled out, the next step is to check whether the solar panel can be charged. Usually, the failure to charge is mainly manifested as voltage and no current. At this time, it is necessary to check whether the battery board joints are well welded and whether the aluminum foil on the battery board has current. If there is current on the solar panel, pay attention to whether it is covered by snow and cannot be charged.
3. Then check whether the line is damaged. If the insulating layer is worn, the current is conducted through the lamp pole, which will cause a short circuit and the lamp will not light up. Some solar street lights are also on during the day and cannot be turned off. In this case, 80% of the controller components are burned out.
