Intelligent solar controller-how to identify which part of the solar street light has a problem 
In this article, we continue to introduce how to use the indicator light of the intelligent controller to identify which component of the solar street light has a problem and replace it.
In the previous article, we introduced three situations, and the fourth situation is that the first idle green light is off, the second charging green light is always on, and the third discharging red light is off. This situation occurs if it is daytime. Then the solar panel should be no problem. If the solar led street light does not light up at night, and this situation occurs at this time. It means that the battery is probably damaged. At this time, just replace the battery.
The fifth situation is that the first idle green light is off, the second charging green light is off, and the third discharging red light flashes. This shows that the working state is Undervoltage, which means that there may be too many rainy days, the power in the solar battery has been discharged, and the light energy absorbed by the solar electronic panel every day is not enough for the streetlamp to light up. In other words, the electricity in the solar battery is too small to reach the voltage to turn on the street light. So there will be an Undervoltage situation.
The sixth is that the first idle green light is off, the second charging green light is always on, and the third discharging green light flashes. The working state of this hand is Undervoltage plus charging. The difference from the fifth state is that the fifth state is most likely to occur at night; the sixth state is in the street light, and if there is no problem, it shows that there is no problem with the solar battery and the solar panel. It is still the same as the previous one . The situation is the same. It is too many rainy days or the electronic board configuration is too small, resulting in insufficient charging capacity. The solar battery has been unable to reach the starting voltage of the led street lamp. This shows that it is not a good thing to configure the battery to be too large. In contrast, in areas with better sunlight, it is a better configuration to appropriately increase the solar panel and reduce the solar battery.
The seventh, the first idle green light is off, the second charging green light is always on, and the third discharging red light is always on. This is a non-light control mode, that is, the brightness of the used light may not be adjusted to turn on Street lights and turn off street lights.
The last mode is that the first idle green light is always on, the second charging green light is always on, and the third discharging red light is off. The reason for this may be that the controller model does not match the software model. At this time, you need to change a controller or a handheld programmer.
