Bai Tianliang solar street lamps light reason:

1, the solar panels during the day, not by the controller to recharge the battery.

controller detection: controller turns red, said it was charging, and the red light flashing said the battery is full of, with pulse controller are small current charging.

solar panel: solar panel connection 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, controller in connection because of is negative after the cause of the controller components burnt down.
