The operation of solar street lights is relatively simple, it is a process of charging and discharging. The solar panel generates electricity during the day and the battery supplies power to the lamp head at night. The process is cycled every day. If the solar street lamp fails, such as the lighting time is shortened, the lamp does not turn on. How do we find out why?
First of all, you need to know whether the lighting time of the lamp is short or not bright. If the lighting time is short, it means that there is a problem in the configuration of the lamp or the power generation of the panel is not enough. The reason may be that the configuration is unreasonable and the configuration is relatively small, or it may be on the panel. A thick layer of dust is attached. This situation is relatively common in riverside areas. The lighting time in winter is short, and the number of consecutive cloudy days is short. In this case, just clean the battery board and take care of it according to the degree of adhesion That's it.
The situation that the lamp is not bright is more concentrated when the controller is broken or the battery is broken, the led lamp head is less damaged, and the damage to the battery board is also less. If there is a problem with the controller, the troubleshooting method is that we use a voltmeter Measure the voltage of the battery board and the voltage of the battery. If there is sunlight in the daytime, the voltage of the battery board is higher than 12v, indicating that the battery board is no problem. If the battery voltage is also above 10v, the battery is also normal, then we can consider replacing Take a look at a new controller. After the replacement, the lamp will be illuminated in 1 to 2 natural days. It means that it is the problem of the controller. Generally, the situation where the battery board and the battery are normally not bright is relatively small. If we measure the battery board ’s The voltage is lower than 10v in the daytime, then we need to check whether the wires of the battery board are connected well. If the wiring is intact, and the battery board is still low in voltage, this may be a problem with the battery board, but such a situation occurs Very few, most of the cases are concentrated on the battery, the battery voltage is less than 10v, generally The controller is the preferred situation is a problem leading to loss of electricity and can not discharge the battery fully charged in time, and the second is the quality of secondary batteries, long-term use leads to resistance too, can not the normal charge-discharge.
In short, if the lamp is not bright, we prefer to consider changing the controller. If the lamp is not lit for a long time, then we recommend replacing the battery.
Wireless level sensor is a high-precision, low-power wireless liquid level detection instrument, which consists of input liquid level sensor, signal processing circuit, communication module and power module. It uses a high-capacity, high-energy lithium battery, radio frequency radio transmission data. Installation is simple, easy to use, no need site wiring, leaves out the conventional instrument wiring bypass trouble, save manpower and construction cost, especially suitable for unwired and unpowered application site.
