According to the working principle of solar street lights, solar street lights will not light during the day, but sometimes will have some trouble, so solar energy street light Bai Tianliang lamp how to return a responsibility? If you have solar street light doesn't close the lights during the day, this kind of situation, said:



according to the working principle of solar street lights, solar street lamp will not light during the day, but sometimes will have some trouble, so solar energy street light Bai Tianliang lamp how to return a responsibility? If there are any solar street light doesn't close the light during the day, this kind of situation, said: 1, the solar panels during the day, not by the controller to recharge the battery. 1) Controller detection: controller turns red, said it was charging, the battery is full of red light flash, with pulse controller are small current charging. 2) The connection of solar panels, solar panels can cause not charging properly such as is not very strong, usually for a voltage ( Voltage meter test) Normal, open circuit voltage at 17. More than 5 v, but there is no current. The phenomenon of panels line not connected well ( Welding cold joint or joint unstable) Screening method can be directly behind the panels of black electrical cover opened, direct voltage, ampere meter for testing data. Such as direct from aluminum panels is no current, the mooring test indicates a problem to change the panels. 2, the controller in connection because of is negative after the cause of the controller components burnt down.
