There are a few reasons why the solar lights suddenly turn off:
1. The controller of the solar street light is connected incorrectly. For the lighting of solar street lights, it is generally controlled by the controller. If the solar street lights are on and off when they are on, the lighting time is relatively short, they are on during the day, they are not on at night, or they are always on, this problem is more obvious. It's because of a problem with the controller, the solution is to reconnect the controller. If there is no indicator light on the solar street light controller, the surface controller is faulty, and the corresponding controller should be repurchased.
2. The solar light does not light up, flickers or does not light up from time to time. It may also be the cause of the light bulb. The light bulb may be naturally damaged or artificially damaged.
3. The battery is also a failure-prone link. The batteries used by many manufacturers are not waterproof. Once in water, the positive and negative electrodes of the battery will short-circuit, causing voltage instability. During the test, carefully observe the change of the battery voltage with the depth of discharge. If it does not work normally, it should be replaced in time.
