Things To Know About Controller in Solar Streetlight

Solar streetlights are famous for the pros of green, clean and economical. If you are strolling on the street, the solar streetlights can be seen everywhere. These public infrastructures are powered by solar energy. They save a lot of energy bills for the government every year. Because the solar streetlights don't rely on the on-grid electricity. How can solar power light up the street light? Most people don't know how the solar streetlight work?

1. Function of the controller in solar streetlight

The solar streetlight controller is a core device that controls and connects the lamp holder, solar panel, and battery. As an independent system, solar streetlights mainly include solar panels, batteries, solar controllers, lamps, light poles, cables and other components. The controller mainly plays a charge and discharge control management in this system. In the sunny day, the solar panel generates electricity through the controller during the day and stores it to the battery, and the battery supplies power to the light source through the controller at night; when the rainy day is too long, the solar panel does not generate electricity to charge the battery, and the battery powers the street light at night. When the battery capacity is below the undervoltage point of the controller, the solar controller disconnects the battery and continues to supply power to the load.

The solar controller can also set the time period, and the solar power street lamp will output current and start working at the set time period. When the solar streetlight is working, the controller can also adjust the power. Adjusting the power can control the brightness of the LED lights, such as adjusting the street light to 30W in the early morning and 15W in the late night to save energy, which locks the current. It not only meets the lighting needs at night, but also saves the overall configuration and budget of batteries and solar panels, and can greatly effectively extend the lifespan of LED lights.

2. How to choose high quality controller for the solar streetlight?

• Choose a controller with two channels of power regulation. Power regulation controllers have been widely promoted. One or two channels of lighting can be automatically turned off at night when there are fewer people to save electricity. You can also adjust the power of LED lights. 

• The controller with lower power consumption should be selected. The controller works 24 hours a day. If its own power consumption is large, it will consume part of the power. It is best to choose a controller with a power consumption of less than 3 mA.

• Choose a controller with high charging efficiency. The controller with MCT charging mode can automatically track the maximum current of the battery panel. Especially in winter or when the light is insufficient, the MCT charging mode is about 20% more efficient than other controllers.
