Common faults of solar street lamps and treatment methods

1. There is voltage on the solar panel, but it cannot be charged, and the green LEDI light is off. Check whether the solar panel terminal interface of the controller is in reliable contact

2. The charging indicator LEDI (green light) flashes quickly. The system voltage is over-voltage. Check if the battery is open circuit or if the battery is connected reliably. Or the charging circuit is damaged

3. The load indicator LED3 (red light) is on, but the load is not working. Check whether the load terminal wiring is reliable

4. The load indicator LED3 (red light) flashes quickly, and the load is not working, the load is short-circuited

5. The load indicator LED3 (red light) flashes slowly, and the load is not working. The load power is too large

6. LED2 displays red, and the load is not working. Battery voltage protection, please charge

7. The whole light does not light up. Solar street lights are used for outdoor lighting, often encounter high temperature and rain, low temperature rain and snow, and solar street light controllers are usually installed in the poles, which can easily cause water to enter the controller to short-circuit. First observe whether there are water traces and rust on the terminal of the controller. If it is very likely that the controller is damaged and no battery voltage measurement is performed, such as a 12V solar street light power supply system, the battery voltage is lower than 10.8V, the battery is no longer storing electricity. , Needs to be replaced. Then check whether there is voltage and current output under normal working conditions of the folding sky battery board. If the battery board is damaged, replace the battery board. All of the above are okay, you should check the light source, only connect to the light source to see if it is on, and if it is not on, replace the light source.

8. The lamp cap flashes. The cause of this failure is poor line contact, battery power loss, and serious decline in power storage. If the line is okay, replace the battery.

9. The lighting time is short, and the duration of rainy days is short. It is usually caused by a decrease in the storage capacity of the battery and sufficient storage capacity. Just replace a reasonable battery.

10. The solar street light source is not fully bright. Many solar street lights use dot-matrix LED light sources. In addition to the quality of the LED light source itself, some weak soldering of the lamp beads will cause this situation. The solution is to replace the corresponding lamp beads, weld firmly or replace the entire street lamp head.
