IP65 LED Solar Street Light

What are the reasons why the solar light suddenly does not turn on? 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 connector is well welded. If there is current on the solar panel, pay attention to whether it is covered with snow and cannot be charged. Third, the water-proof problem of the battery, which causes the positive and negative poles of the battery to short circuit after the water enters, causing the voltage to be unstable. During the test, carefully observe the change of battery voltage with the depth of discharge. If it cannot be used normally, it needs to be replaced with a new one.  Parameter table Product LED Solar Flood Light Power 60W 120W 200W …
