1. The solar street light is flickering and the brightness is unstable. For this reason, first replace the lamp. If the lamp is still flickering after replacing the lamp, the problem of the lamp can be ruled out. At this time, check the circuit, which is probably the interface of the circuit. Caused by poor contact. Second, solar street lights can only last for one to two days in rainy days. There are two main reasons for this. Dissatisfaction of solar battery charging. Dissatisfaction of solar battery charging is the reason for solar charging. First, observe how the weather is near, whether it can guarantee charging for about 5-7 hours a day. If charging only lasts for 2-3 hours, this situation is normal. Please rest assured. In addition, check whether the battery is aging, the battery life is 4–5 years under normal working conditions. Third, the solar street light stops working. When the solar street light stops working, first check whether the controller is broken. The main reason for this situation is that the solar controller is broken and repair it in time. The above are three reasons why solar street lights are prone to frequent problems; but, in the final analysis, it is a quality problem; good quality street lights, after reasonable installation, will basically have no problems; I have a deep understanding of this, and I have done one before. The reason for batching street lights is that the quality is too poor, and there are often large and small problems. Later, we replaced the solar street lights we produced, and after they were installed, they worked normally without any problems.
The red light on the controller means that it is charging, and the flashing red light means that the battery is full, and the controller is charging with a small pulse current. The yellow light of the controller indicates that the battery has lost power and cannot be normally illuminated. At this time, if the battery cable is disconnected and then reconnected, the light will be on. At this time, the controller detects that the battery has been charged for a day and the battery capacity has increased. , Not the floating voltage of the battery.
The solar street lights we installed used gel batteries or lead-acid batteries in the past. Now some solar street lights do not light up, and some solar street lights have a short lighting time. How to repair these faults? Can lead-acid batteries be replaced with lithium batteries? Can the gel battery be replaced with a lithium battery? How much does it cost to replace the battery?
