Possible faults of solar street lamps:
1. No light
The newly installed ones don't light up.
① Troubleshooting: the lamp cap is connected reversely, or the lamp cap voltage is incorrect.
② Troubleshooting: the controller is not activated after hibernation.
● Reverse connection of solar panel.
● The solar panel cable is not connected properly.
③ Switch or four core plug problem.
④ Parameter setting error.
Install the light and keep it off for a period of time
① Battery power loss.
● The solar panel is blocked.
● Solar panel damage.
● Battery damage.
② Troubleshooting: the lamp cap is broken, or the lamp cap line falls off.
③ Troubleshooting: whether the solar panel line falls.
④ If the light is not on after several days of installation, check whether the parameters are wrong.
2. The light on time is short, and the set time is not reached
About a week after installation
① The solar panel is too small, or the battery is small, and the configuration is not enough.
② The solar panel is blocked.
③ Battery problem.
④ Parameter error.
After running for a long time after installation
① Not enough light in a few months
● Ask about the installation season. If it is installed in spring, summer and autumn, the problem in winter is that the battery is not frozen.
● If it is installed in winter, it may be covered by leaves in spring and summer.
● A small number of problems are concentrated in one area to check whether there are new buildings.
● Individual problem troubleshooting, solar panel problem and battery problem, solar panel shielding problem.
● Batch and focus on regional problems, and ask whether there is a construction site or mine.
② More than 1 year.
● Check the problem first according to the above.
● Batch problem, battery aging.
● Parameter problem.
● See if the lamp cap is a step-down lamp cap.
3. Flicker (sometimes on and sometimes off), with regular and irregular intervals
Regular
① Is the solar panel installed under the lamp cap.
② Controller problem.
③ Parameter error.
④ Incorrect lamp cap voltage.
⑤ Battery problem.
Irregular
① Poor contact of lamp cap wire.
② Battery problem.
③ Electromagnetic interference.
4. Shine - it doesn't shine once
Just installed
① Incorrect lamp cap voltage
② Battery problem
③ Controller failure
④ Parameter error
Install for a period of time
① Battery problem
② Controller failure
5. Set morning light, no morning light, excluding rainy days
The newly installed one doesn't light up in the morning
① Morning light requires the controller to run for several days before it can automatically calculate the time.
② Incorrect parameters lead to battery power loss.
Install for a period of time
① Reduced battery capacity
② The battery is not frost resistant in winter
6. The lighting time is not uniform, and the time difference is quite large
Light source interference
Electromagnetic interference
Parameter setting problem
7. It can shine during the day, but not at night
Poor contact of solar panels
