Possible faults of solar street lamps:
1.No light
The newly installed ones don’t light up
①Troubleshooting: the lamp cap is connected reversely, or the lamp cap voltage is incorrect.
②Troubleshooting: the controller is not activated after hibernation.
·Reverse connection of solar panel
·The solar panel cable is not connected properly
③Switch or four core plug problem
④Parameter setting error
Install the light and keep it off for a period of time
①Battery power loss
·The solar panel is blocked
·Solar panel damage
·Battery damage
②Troubleshooting: the lamp cap is broken, or the lamp cap line falls off
③Troubleshooting: 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
①The solar panel is too small, or the battery is small, and the configuration is not enough
②The solar panel is blocked
③Battery problem
④Parameter error
After running for a long time after installation
①Not 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
②More 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
①Is the solar panel installed under the lamp cap
②Controller problem
③Parameter error
④Incorrect lamp cap voltage
⑤Battery problem
Irregular
①Poor contact of lamp cap wire
②Battery problem
③electromagnetic interference
4.Shine – it doesn’t shine once
Just installed
①Incorrect lamp cap voltage
②Battery problem
③Controller failure
④Parameter error
Install for a period of time
①Battery problem
②Controller failure
5.Set morning light, no morning light, excluding rainy days
The newly installed one doesn’t light up in the morning
①Morning light requires the controller to run for several days before it can automatically calculate the time
②Incorrect parameters lead to battery power loss
Install for a period of time
①Reduced battery capacity
②The 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
