What are the reasons why the whole set of solar street lights does not light up?

The solar power street lamp does not light up all day. Possible reasons include incorrect wiring, problem with the light source, short circuit of the line water inlet controller, and too long continuous rainy days. And we first need to check the solar power street lamp controller, look at the above logo, check whether the corresponding logo circuit is correctly connected, and then observe whether there is water rust on the terminal of the controller, if it is very likely the controller has been If it is damaged, measure the battery voltage. If the battery voltage of the 12V solar street light system is lower than 10.7V, the battery is out of service. Replace the battery. When there is light on a sunny day, check whether the solar panel has current and voltage output. If there is, the solar panel is normal, and if there is no solar panel, the solar panel is damaged.

If the above problems do not exist, it is a problem with the light source of the led lamp. Connect the light source to other power sources and check to see if the light is on. If it does not light, change the light source of the lamp. If it is a few consecutive rainy days, the solar power street lamp does not light up normally, because the solar panel does not generate electricity, and the power stored in the battery has been used up. When there is light on a sunny day, the solar panel continues to charge the battery and the solar power street lamp will light up normally. 

The solar power street lamp system can guarantee normal operation for more than 15 days in rainy weather! Its system is composed of several parts (including bracket), LED lamp holder, solar lamp controller, battery (including battery incubator) and light pole.

LED lamp holders generally use high-power LED light sources;

Solar cell modules generally use monocrystalline silicon or polycrystalline silicon solar cell modules;

The controller is generally placed in the light pole, with light control, time control, overcharge and over-discharge protection, and reverse connection protection. More advanced controllers have the function of adjusting the lighting time in four seasons, half power function, intelligent charging, and discharging function, etc.; The battery is generally placed underground or there will be a special battery incubator. Valve-regulated lead-acid batteries, gel batteries, iron-aluminum batteries, or lithium batteries can be used. The solar lamps work fully automatically and do not need to dig trenches for wiring, but the light poles need to be installed on the embedded parts (concrete base)
