1. The whole set of solar street lights is not bright
The whole set of solar street lights are not bright. The possible reasons are incorrect wiring, problem with the light source, short circuit of the water inlet controller, and too long continuous rainy days. First check the controller of the solar street light, take a look at the above logo, check whether the corresponding logo line is correctly connected, and then observe whether there is water rust on the terminal of the controller. If there is a high possibility that the controller is damaged, if not, measure Battery voltage. If the battery voltage of the 12V solar street light system is lower than 10.7V, the battery can no longer be used. Replace the battery. When there is light on a sunny day, check whether the solar panel has current and voltage output. If there is, the solar panel is normal, and if not, the solar panel is damaged. If none of the above problems exist, there is a problem with the light source of the led lamp. Connect the light source and other power supply to check whether it is on. If it is not on, change to a light source. If it is several consecutive rainy days, the whole set of solar street lights will not turn on normally, because the solar panel does not generate electricity, and the power stored in the battery has been exhausted. When there is sunshine on a sunny day, the solar panel continues to charge the battery and the solar street lights will turn on normally.
2. LED light source flashes
The main reason for the LED light source flickering is the wiring problem, or the battery may be running out of power. First, check whether the wiring is correct, whether the connection and wrapping of each node are normal, and you can reconnect the wiring again. If the light source is still blinking, it is necessary to consider that the battery is out of power. Measure the open circuit voltage of the battery with DC voltage. If the voltage is lower than 12v, the battery is deficient. Connect the positive and negative electrodes of the battery and the positive and negative electrodes of the solar panel correctly. The system can be used normally after charging for 1-2 days.
3. The lighting time is short, and it will not light when it rains
There is only one reason for this failure. The capacity of the battery is too small. If it is newly installed, it means that the battery capacity issued by the manufacturer is false, and it cannot meet the lighting requirements of continuous rainy days. If the solar street lamp has been used for several years, It indicates that the battery has decayed to the end of its service life, and the battery can be replaced.
4. The light source of the led lamps is not all bright
Some places in the light source of Led lamps are bright, and some places are not bright. At present, the commonly used solar street light LED light sources are officially arranged, and some bright and some are not bright, indicating that the quality of this led lamp bead is not good or the specifications are not uniform, resulting in the same voltage and current. Work may also be caused by virtual welding during the welding process, and some lamp beads have poor contact. In this case, just replace the light source of the LED lamp, and the solar street light will be normally lit.
