With the development of technology, the current street lights are mostly converted by solar energy, so that energy saving, safety and convenience can be achieved. And it is equipped with a solar street light controller, which can be controlled and displayed by a microprocessor, and uses high-quality, low-loss, and long-life components to ensure reliable performance, so that the solar street light system can last forever Normal work, reducing system maintenance costs. So what is the function of the solar street light controller? Next, the editor of Century Sunshine Lighting will introduce to you.
1. Control function The basic function of the solar street lamp controller is of course to have a control function. When the solar panel irradiates the solar energy, the solar panel will charge the battery. At this time, the controller will automatically detect the charging voltage to provide the solar lamp Output voltage, so that the solar street light will light up.
2. Voltage stabilization When solar energy irradiates the solar panel, the solar panel will charge the battery. At this time, its voltage is very unstable. If it is directly charged, it may reduce the service life of the battery, and may even cause damage to the battery. The controller has a voltage stabilizing function in it, which can perform constant voltage current limiting on the voltage of the input battery. When the battery is fully charged, it can charge a small part of the current or not.
3. Boost function The controller of the solar street light also has a boost function, that is, when the controller cannot detect the voltage output, the solar street light controller controls the output voltage from the output terminal. If the battery voltage is 24V, but it reaches normal 36V is required to turn on the light, and the controller will increase the voltage to bring the battery to a level capable of turning on the light. This function is to be able to realize the lighting of LED lights only through the solar street light controller.
