1. The solar panel has voltage but cannot charge. If the LED indicator light is not on, check if the connection at the controller’s solar panel interface is secure.
2. If the charging indicator light (green) is flashing quickly, it indicates that the system voltage is overcharged. Check if the battery is open circuit, or if the connection of the battery is secure. Alternatively, the charging circuit might be damaged.
3. If the load indicator light (red) is on but the load is not working, check whether the load terminal connections are secure.
4. If the load indicator light (red) is flashing quickly and the load is not working, it indicates a load short circuit.
5. If the load indicator light (red) is flashing slowly and the load is not working, it indicates an overload condition.
6. If LED2 shows red and the load is not working, it is a battery voltage protection indication. Please recharge the battery.
7. If the whole light does not turn on, check if there are any water marks or rust on the controller’s terminal. If rust is present, the controller is likely damaged. Measure the battery voltage; if a 12V solar streetlight system shows a voltage below 10.8V, the battery needs replacement. Check if the solar panel is outputting voltage and current when working normally. If not, replace the solar panel. If all of these are fine, check the light source by directly powering it. If it does not light up, replace the light source.
8. If the light head is flickering, possible causes include poor wire contact, battery depletion, or a significant drop in stored energy. If the wiring is fine, consider replacing the battery.
9. If the lighting duration is short, especially during rainy or overcast days, it is usually due to reduced battery storage capacity. Replacing the battery with a suitable one will resolve this.
10. If the solar streetlight source does not fully illuminate, it might be due to issues with the LED light source itself, including poor soldering of some light beads. The solution is to replace the faulty light beads or the entire light head.
