First, solar LED street light maintenance common faults

1. Battery problems.

If the lighting time is short, the battery energy storage drops, resulting in rainy weather, and the lighting time is short, that is the problem of the battery, and the battery should be replaced.

2 LED light source problems.

Solar street lamp beads are not fully bright, in addition to the quality problems of the LED light source itself, it is a welding problem, should be replaced in time to replace the lamp beads or the lamp bead welding or more directly replace the lamp head.

3 Installation site problems.

In places where solar street lights are installed, the lack of sunlight and the inability to store energy for batteries is also a major problem. The solar street lamp system suitable for this place should be found to meet the lighting needs.

4 The line is faulty.

The line connection is poor, the battery is fed, the energy storage is reduced, and the light will flicker. It should be replaced or repaired in time where the line is in poor contact.

5 What is the problem if the whole light is not on?

First of all, check whether the controller is in the water, if it is not the controller problem, it is in the test battery voltage, voltage is lower than 10.8v, if not, then see if the panel has voltage, if there is no voltage to change the panel.

Second, solar LED street lamp fault solution

Light is not bright possible fault parts: LED light source, solar controller, battery;

Solar panel solution:

1. First check whether the wiring terminals of the lamps are loose.

2, remove the LED light source, connected to the battery or DC12v power supply to see whether the light is working normally, pay attention to the positive and negative poles, the light is not on indicates that the LED light is faulty, need to replace the LED light, the light indicates that the controller or the battery is faulty.

3, Measure the battery power supply, if it is lower than 11v, it indicates that the controller is in the protection state, and the lamp is fully charged before use. If the value is higher than 11v, the controller is faulty and needs to be replaced.

LED light working time is short

Possible faulty components: Solar controller, solar panel

The solution:

1, the solar controller is wrong, please reset the professional understanding.

2, there is dust on the solar panel, clean the dust to make it provide power generation efficiency.

3, rainy weather more than 3 days, such as the weather can be restored to normal.

The LED light is not enough

Possible failure parts: lamp shade, LED light

The solution:

1, clean the lampshade, make it clean.

2. Clean the dirt in the contact part of the positive electrode of the light source and the spring plate to make it conductive;

3, solar street lights if there are other faults need to ask professionals to check and repair!

Matters needing attention

1, whether the solar controller water

2, whether the panel has current

3. Whether the battery voltage is higher than 10.8v
