First, the detection of led separate solar flood light controller, controller is the core of solar street light. The red light means that the battery is being charged, and the flashing light means that the battery is fully charged. If it is yellow, it means that the power is deficient and the light cannot be normally turned on.
At this time, it is necessary to detect the battery voltage of Led independent solar searchlight. If the battery is normal, then replace the new controller to see if it is normal. If it is normal, it is basically determined that the controller is broken. If the indicator is off, check whether the cable is disconnected.
Second, if the fault of the controller is eliminated, the next step is to detect whether the solar led bollard light can charge, usually can not charge the situation is mainly manifested as voltage without current. At this time, check whether the panel joint is welded.
Connect, the aluminum foil on the panel has no current, if there is no current, it is basically concluded that the panel has been scrapped. If there is an electric current on the solar panel, also be aware of snow cover, which makes it impossible to charge.
Third, the battery is also prone to failure of a link. Many manufacturers use batteries are not waterproof, which leads to battery water after the positive and negative short circuit, resulting in voltage instability. Solar garden light manufacturers take a close look at batteries when testing them.
Fourth, finally check whether the line is damaged. If the insulation wears away and the current passes through the pole, it will cause a short circuit and the light will not turn on. By the way, some solar street lights also shine during the day.
