Solar Street Light Factory: How to repair solar street lamp?

• Common faults in solar street light maintenance

1. The problem of the battery. If the lighting time is short, the energy storage of the battery decreases, resulting in rainy weather, and the lighting time is short, that is the battery problem, the battery should be replaced.
2. The problem of LED light source. In addition to the quality problem of the LED light source itself, the lamp beads of the solar street light are not fully lit.

The failed lamp beads should be replaced in time or the lamp beads should be welded firmly or the lamp head should be replaced more directly.
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. It is necessary to find a solar street light system suitable for this kind of place to meet the lighting needs.
4. Line problems. Poor line connection, battery feeding, and reduced energy storage will cause the lights to flicker. It should be replaced or repaired in a timely manner where the line is in poor contact.
5. What is the problem if the whole light does not light up? First, check whether the controller is flooded with water. If it is not the problem of the controller, check whether the battery has voltage and whether the voltage is lower than 10.8v.
