The reason why solar street lamps don't work.

The reason that the solar street lamp doesn't work is that the solar cell is damaged, the solar controller is damaged and the line is aging.

The causes and solutions of solar energy failure are as follows:

1, solar battery damage: solar street lamps use lithium batteries or lead-acid batteries, and the batteries have a certain service life. If it is used for too long, the battery will be damaged and the solar street lamp will not light up.

Solution: Try to choose lithium batteries with long service life when installing, maintain and protect them constantly during use, and replace them with new ones in time after reaching a certain service time.

2. Damage of solar controller: The solar controller is damaged due to wind and rain, or the controller cannot work normally due to other reasons.

Solution: replace the new controller in time, dismantle the original controller, select the controller of the same model and debug it.

3. Line aging: Line aging is the most common damage mode and cannot be used after aging.

Solution: Pay attention to the maintenance of solar street lamps at ordinary times.
