Streetlights are ubiquitous in our lives, especially in metropolitan areas. When they are lit at night, the cityscape becomes particularly beautiful. Currently, cities are focusing on energy saving and environmental protection, resulting in a prevalence of solar streetlights. With the solar streetlight controller being a crucial component, how should one choose it? The following is an introduction to this topic.
1. Choose a controller with low power consumption. Since the controller operates continuously 24 hours a day, high power consumption may drain some energy. It is best to select a controller with a power consumption below 1 milliamps.
2. Opt for a controller with high charging efficiency. Controllers with MCT charging mode can automatically track the maximum current of the solar panel. Particularly during winter or periods of insufficient sunlight, MCT charging mode can achieve about 20% higher efficiency compared to others.
3. Select a controller with dual power adjustment capabilities. Controllers with power regulation have become widely promoted. They can automatically turn off one or both lighting circuits during periods of low pedestrian traffic at night, saving electricity, and can also adjust the power for LED lights. In addition to these energy-saving features, it is also essential to pay attention to the controller’s ability to protect components such as batteries. For instance, controllers with trickle charging mode can effectively protect the battery, extending its lifespan. Additionally, when setting the undervoltage protection value for the controller, it is advisable to set it at ≥ 11.1V to prevent over-discharging of the battery.
The above information on selecting a solar streetlight controller is shared here. A solar streetlight controller is a comprehensive and versatile device that enhances the intelligence of our streetlight systems. Living comfortably and pleasantly is truly wonderful, and smart solar streetlight controllers keep our nights illuminated. The design and working principles of solar streetlight controllers are relatively simple.
