1. The whole light is not on; the
solar street light is used for outdoor lighting, and it often encounters high temperature and rainy weather, low temperature rain and snow, and the solar street light controller is usually installed in the light pole, which is easy to cause the short circuit between the water entering the controller and the controller. . First observe whether the terminals of the controller have water stains and rust. If there is a possibility that the controller has been damaged, no battery voltage measurement is performed. For example, in a 12Vsolar street light power supply system, if the battery voltage is lower than 10.8V, the battery is no longer charged. , need to be replaced in time. Then check whether the solar panel has voltage and current output under normal working conditions. If not, the battery board is damaged, replace the battery board. If there is no problem with the above, you should check the light source, only connect the power supply to the light source to see if it is lit, if not, replace the light source. 2. The lamp head is flickering; the reason for this failure is that the line is in poor contact, the battery is out of power, and the stored power is seriously reduced. If the line is no problem, replace the battery. 3. The lighting time is short, and the duration of cloudy and rainy days is short; it is usually caused by the decrease in the storage capacity of the battery and the sufficient storage capacity. Just replace the battery with a reasonable one. 4. The light source of solar street light is not fully lit; many solar street lights use dot-matrix LED light source, in addition to the quality problem of the LED light source itself, some lamp beads will cause this situation. The solution is to replace the corresponding lamp beads, weld firmly or replace the entire street lamp head.
