![]() No lighting at night, no indicator light on microwave sensorġ. If the voltages in the evening and morning are consistent, the battery cannot be charged.Ģ) When measuring the voltage of the solar panel with a multimeter, you must place the solar panel under the sun, open the junction box to test the charging voltage, or directly test the voltage of the waterproof cable connectorģ) Testing the solar panel Voltage, current Testing the battery Voltage, current.ī. Test battery function (please refer to B below)ġ) Record the battery voltage value in the morning and the battery voltage value in the evening. Test Solar Panel Function (please refer to B below)ī. The lamp will be lighting automatically at nightĢ) If you charge the battery on sunny days for a few days, and the light still does not turn on at night, the solar panel cannot be charged or the battery cannot be discharged.Ī. If the green light flashes during the day, it indicates that the charging is normal. The red light is always on and the battery is no power.ġ) Observe whether there is no sun for several days in a row, wait for the next day to charge the battery, and observe the charging status of the lamp during the day. Use adjustable power supply to adjust the light source voltage to 36V / 24V / 12V (according to your light source voltage), test whether the LED light source is on normally, if it is not confirmed, replace with a new light source 3. If it is normal, it means that there is a problem with the controller, just replace the controller if the load is still off, the LED light source is defective.Ģ) Check the function of the LED light source. Call the normal function controller from the side to the light body, and connect to test whether the load is working normally. The red light is flashing and the load is not on.ġ) Check the controller function. If there are two cases, remove the strong light or remove the solar street light if there is no strong light around, you need to replace the controller. The green light flashes.įirst check whether there is strong light around, or whether the moonlight is very bright. No lighting at night, but there are indicators 1. Troubleshooting methods for solar street lights A. No instructions (the battery is dead or the cables are not in contact or the controller is broken)Ģ.Fast red flashing (2 times per second, indicating that the load is short-circuited and the light is not on)-LED function is abnormal, the positive and negative poles of the light source are reversed. ![]() Red light flashes slowly (once every 1 second, the load is disconnected, and the light is off)-LED function is abnormal, and the light source cable is not connected well.The red light is always on (the battery is over-discharged) - the battery function is abnormal and the battery is depleted.Traffic lights light up together (battery voltage is lower than 12V)-function is normal. ![]()
