The Reason Why The Solar Street Light Does Not Shine

LONGT Lighting Group Co.,Ltd | Updated: Aug 09, 2017

  The reason why the solar street light does not shine

  1, LED light source damage (about 25%) due to natural or man-made causes of LED light source damage, resulting in solar street light system can not work, when the light is not bright, flashing and so on. Solution: Check the LED light source or replace the LED light source.

  2, solar panel damage (about 5%)

  Please test the open circuit voltage of the solar panel.

  Solar panels in the sun without any load, do not link the controller, directly to the solar panels to pull out the wire, even on the multimeter to test its voltage, because your system is 12V system, so the solar panel voltage under normal circumstances Will show higher than 12V, the system of the domestic board will generally use the working voltage of 18V solar panels, so its open circuit voltage will be more than 18V (experience should be judged to be about 18-21V).

  Note Only when the voltage is higher than 12V can the battery charge, if less than 12V can not charge the battery. ]

  Solar street light system can not work or work time is not enough. Solution: Replace the solar panels.

  3, the solar panel positive and negative reverse (about 1%) [Please confirm whether the positive and negative battery panel is reversed]

  Solar street light system installation will only light once, when the battery is running out after the solar street lights will never light up. Solution: Replace the solar panels positive and negative.

  4, constant current source damage (about 10%) [system restart the bulb work, has been excluded]

  Solar street light system can not work, LED lights will not light or flash. Solution: Check the constant current source or replace the constant current source directly.

  5, the controller set the wrong (about 5%) [controller panel no button, you need to add a handheld or data cable connected to the computer with software reset, please contact the sea lighting assistance]

  Solar street light system can not work properly, LED lights when the light is not bright, bright time is not enough, daytime bright night or always lit. Solution: Reset the controller and replace the controller directly.

  6, the controller program error (about 5%) [controller panel no button, you need to add a handheld or data cable connected to the computer with software reset, please contact the sea light lighting]

  Solar street light system can not work properly, LED lights when the light is not bright, bright time is not enough, daytime bright night or always lit. Solution: Change the controller program and replace the controller directly.

  7, the controller hardware damage (about 10%)

  Solar street light system can not work properly, LED lights when the light is not bright, bright time is not enough, daytime bright night or always lit. Solution: Change the controller hardware and replace the controller directly.

  8, the controller connected wrong (about 10%) [Please follow the system installation instructions to check whether the wrong]

  Solar street light system can not work properly, LED lights when the light is not bright, bright time is not enough, daytime bright night or always lit. Solution: Reconnect to the controller.

  9, the battery is negative and negative lead, poor contact, life expiration, battery damage, so that the battery can not work properly, the voltage is too low (about 10%) [Please confirm whether the positive and negative battery reverse, test the battery Broken. With their own power to the battery charge, 12V battery is full of test voltage should be normal when about 13.8V, and then the battery directly connected to the load (note that at this time do not access the controller), with a multimeter to test the voltage to see the voltage changes, If the voltage is relatively slow to slow down that the battery is normal, if the voltage in a short time (a few minutes of time) will soon be reduced that the battery is broken]

  Solar street light system can not work, LED lights do not shine, bright time is not enough, brightness is not enough, when the light does not shine. Solution: Reconnect the battery, replace the battery, replace the battery terminal, repair the battery or replace the battery directly.

  10, line aging or line disconnection (about 14%)

  Solar street light system can not work, LED will not light or flash. Solution: Reconnect the wires or replace the wires.

  11, man-made solar street light system hardware damage (about 5%)

  The solar street light system does not work properly. Solution: Hardware repair or replacement damage to the hardware.
