With the development of technology, modern streetlights predominantly use solar photovoltaic energy for conversion, achieving energy-saving, safety, and convenience. They are equipped with solar streetlight controllers, which are intelligent charge and discharge controllers controlled and displayed by microprocessors, utilizing high-quality, low-loss, and long-lasting components to ensure reliable performance. This enables the solar streetlight system to function effectively over a long period, reducing system maintenance costs. So, what functions does the solar streetlight controller serve? Let’s explore.
1. Control Function
The primary function of a solar streetlight controller is control. When the solar panel is exposed to sunlight, it charges the battery. The controller automatically detects the charging voltage and outputs voltage to the solar lights, which allows the solar streetlight to illuminate.
2. Voltage Regulation Function
When sunlight hits the solar panel, the panel charges the battery, but the voltage during this process can be quite unstable. Direct charging could potentially shorten the battery’s lifespan or even damage it.
The controller serves a voltage regulation function, maintaining a constant voltage and current limit for the battery input. When the battery is fully charged, it can either charge with a small amount of current or stop charging altogether.
3. Boost Function
The solar streetlight controller also features a boost function. If the controller cannot detect voltage output, it will control the output voltage. For example, if the battery voltage is 24V but 36V is needed for proper illumination, the controller will boost the voltage to ensure that the battery reaches a suitable level for lighting. This function is essential for the LED light to operate properly.
This concludes our discussion on the functions of the solar streetlight controller. The solar streetlight controller is designed with full encapsulation, a metal body, and is waterproof and shockproof, allowing it to withstand various harsh environments.
