What is the meaning of each indicator light of solar light?

When in the daytime, the solar street lamp controller under the sunlight charging red light (SUN) will be bright (the way of lighting is stroboscopic, the stronger the sunlight, the higher the charging current, the faster the stroboscopic speed);

The two-color light (BAT) represents the capacity of the battery, the red light indicates that the battery has been discharged, the two-color light indicates that the battery is under voltage, and the green light indicates that the battery is normal. Another red light represents the working status of the led: steady on means normal battery discharge, stroboscope means fault.

Faults and indicators

1, during the installation, the led light source will not be extinguished (two-color light green, led red light work normally) When the above situation occurs, we need to test whether their wiring is correct, because the solar street light controller can not receive the voltage transmitted by the solar panel will default to the led has been in the working state until the end of its set working time.

It can also cause it to not work properly the next day. This we need to detect whether the connection between the controller and the solar panel is reversed, and another possible reason is that the solar panel is directly short-circuited (because the high-power panel will be protected by a diode, this side can be cut short to make it work normally).

2. Solar street lights are not bright after a period of time (two-color lights appear red) When the middle light of the solar street light controller appears red, it means that the led light source has been put, and the led light source can automatically cut off the work, and the default voltage of the battery is restored to the over-discharge protection voltage, and the LED light source can continue to work.

3. The night led light source is not bright for a period of time (the two-color light appears yellow) The two-color light appears yellow, indicating that it has been undervoltage, generally appearing after a long period of cloudy and rainy days, and the night will stop working for a period of time.

The way to repair is to remove the line of the led light source, so that the sun can charge for a day or two and work normally (of course, do not connect the line back); In fact, don't worry too much, this side of the solar street light controller will protect the battery.

4.led is not bright (two-color light is not bright or two red indicators are bright) led light source is not bright, we first look at the controller indicator light, if the controller is damaged, there will be an indicator working status is not correct.

In fact, using the solar controller indicator to judge the fault is one of the basic skills of our after-sales solar street lamp maintenance, and we need some other tools to determine some other problems.
