Common troubleshooting methods for solar street lamps

1. There is voltage on the solar panel, but it cannot be charged. The LEDI green light does not light up. Check whether the solar panel end interface of the controller is reliably contacted
2. The charging indicator LED (green light) quickly flashes the system voltage overpressure, and check whether the battery is open or connected reliably. Or the charging circuit is damaged
3. The load indicator LED 3 (red light) is on, but the load does not work. Check whether the load terminal wiring is reliable
4. The load indicator LED 3 (red light) flashes quickly, and the load does not work. The load is short-circuited
5. The load indicator LED 3 (red light) flashes slowly, and the load does not work. The load power is too high
6. LED2 displays red and the load is not working. Battery voltage protection, please charge
7. The entire lamp does not light up. Solar street lamps are used for outdoor lighting, and often encounter high temperature, rainy, and low temperature, rainy, and snowy weather. However, solar street lamp controllers are usually installed inside lamp poles, which can easily lead to water ingress and short circuit to the controller. First, observe whether there are water stains and rust on the terminals of the controller. If there is a high probability that the controller has been damaged, and no further battery voltage measurement has been conducted. For example, in a 12V solar street lamp power supply system, if the battery voltage is lower than 10.8V, the battery no longer stores power and needs to be replaced. Then check whether there is voltage and current output on the folding battery panel under normal working conditions. There is no damage to the battery board. Replace the battery board. "If there is no problem with the above, you should check the light source and only connect the power supply to the light source to see if it is lit. If it is not lit, replace the light source.".
8. The lamp cap flashes. The causes of this failure include poor circuit contact, battery power loss, and a severe decrease in storage capacity. If the circuit is OK, replace the battery.
9. The lighting time is short, and the duration of rainy days is short. This is usually caused by a decrease in the storage capacity of the battery and insufficient storage. Replace the battery with a reasonable one.
10. The light source of the solar street lamp is not fully lit. Many solar street lamps use dot matrix LED light sources. In addition to the quality problems of the LED light source itself, some lamp beads will be subject to faulty soldering, which will cause this situation. The solution is to replace the corresponding lamp beads, weld firmly, or replace the entire street lamp cap.
