Why won't the solar street light just installed in Zhangjiakou 6 meters turn on?

Last Sunday, I sent a batch of rural 6-meter solar street lights to Zhangjiakou, about forty sets. The customer called yesterday and said that there were more than ten sets that did not light up. . Zhangjiakou's 6-meter solar street light just installed, why doesn't it turn on? After receiving the call, the company paid more attention to it, and immediately sent a technician to the scene. Why doesn't the 6-meter solar street light just installed in Zhangjiakou not turn on? After technical investigation, it was found that these lights did not light up because the wiring was reversed, and the lights turned on immediately after rewiring. When installing this batch of Zhangjiakou 6-meter solar street lights, they did not send technicians to the scene, but gave guidance over the phone. The villagers installed them themselves, but they did not pay attention to connecting the wires in the opposite direction, which caused such an oolong. Here, solar street light manufacturer litelsolar reminds everyone to pay attention to the wiring sequence when installing solar street light. How to wire solar street light: First, connect the positive and negative poles of the LED to the corresponding red and black wires on the right side of the controller; then connect the positive pole of the battery , The positive pole of the solar panel is connected to the red line on the left (shared positive pole); then the negative pole of the battery is connected to the third black line from the left, wait for 1 minute, the LED is turned on; finally, the negative pole of the solar panel is connected to the left number. Wait for 1 minute on the second wire, the LED turns off, and the controller enters the charging state. Generally speaking, the solar street light has to be tested and debugged layer by layer before delivery, to ensure that the lights are normally on before the delivery is arranged. If the solar street light you just installed does not turn on, you can check whether the wiring is wrong, or contact the after-sales staff of the solar street light manufacturer to solve it for you.
