Solar street lights maintenance, due to various reasons may cause the polarity of the line can't respectively, in these situations requires some testing tools and means to help us determine the system of battery, solar panel, solar street lamps light source, such as the positive and negative polarity. Bao
in the process of solar street lights maintenance, due to various reasons, circuit polarity may not be separated. In these cases, the tests need some tools and methods to help us determine the positive and negative polarity of battery, solar panels, light source, etc. Solar street light system. Shandong heart yue photoelectric technology co. , LTD. , solar street lighting test according to the following steps: first of all, you need to determine the positive and negative of battery. Using a multimeter traffic lights through rules of DC voltage file can detect the positive and negative of battery ( People know only when used with a multi-meter polarity when connecting the battery voltage to display properly) 。 Then, can be directly connected to the battery light source wires, to see the light is on. The light source can be determined is the cathode wires ( Light is negative after the reverse connection light is not bright, won't damage the light source, can safely test lamps and lanterns) 。 Finally, through the test, we will also find solar street light system for each of the parts if there is any fault. If there is no failure, we can according to the requirements of the controller wiring connections. At the same time, pay attention to waterproof and moistureproof, prevent damage of the controller.
