1. There is voltage on the solar panel, but it cannot be charged. If the LEDI green light is off, check whether the solar panel end interface of the controller is in reliable contact
2. Charge indicator LEDI (green) blinking fast The system overvoltage. Check whether the battery is open or properly connected. Or the charging circuit is damaged
3. The load indicator LED3 (red) is on, but the load does not work check whether the cables to the load terminal are reliable
4. The load indicator LED3 (red) blinks rapidly and the load does not short-circuit
5. The load indicator LED3 (red) blinks slowly and the load does not work. The power of the load is too high
LED2 display red, and the load does not work battery voltage protection, please charge
7. The whole light doesn't work. Solar street lamp used for outdoor lighting, often encounter high temperature and rainy, low temperature rain and snow weather, and the solar street lamp controller is usually installed in the lamp pole, easy to cause its water * controller short circuit phenomenon. First observe the wiring terminal of the controller whether there is water mark rust, if it is likely that the controller has been damaged, there is no battery voltage measurement, such as 12V solar street lamp power supply system, battery voltage is lower than 10.8V, the battery has no power storage, need to be replaced. Then check whether there is voltage and current output under the normal working condition of folding solar panel. There is no damage to the panel. Replace the panel. All the above is no problem, you should check the light source, only to power the light source, to see whether it is lit, not bright to replace the light source.
8. The lamp holder flashes. The cause of this fault, the line contact is poor, the battery is deficient, and the storage quantity is seriously decreased. In the case of no problem with the line, the battery is replaced.
9. Short lighting time, short duration of overcast and rainy days. It is usually caused by the decrease of the storage capacity of the battery. Replace a reasonable battery.
10. The solar street light source is not fully bright. Many solar street lamps use dot matrix LED light source, in addition to the quality of LED light source itself, some lamp bead welding will cause this situation. The solution is to replace the corresponding lamp bead, weld firmly or replace the whole lamp head.
