The photovoltaic street light controller is a device used to control the photovoltaic street light system. Its working principle mainly includes the following aspects:
Maximum Power Point Tracking (MPPT): The photovoltaic street lamp controller automatically adjusts the working voltage of the street lamp by monitoring the output voltage and current of the photovoltaic panel in real time, so that it always works at the maximum power point to improve energy utilization efficiency.
Charge and discharge management: The controller manages the charge and discharge of the battery to ensure that it does not overcharge or over discharge, thereby extending its service life.
Light control and time control: Some photovoltaic street light controllers also have light control and time control functions. The light control function can automatically turn on and off street lights according to the ambient light intensity, achieving intelligent control. The time control function can control the on/off of the street lights according to the preset time, meeting the lighting needs of different time periods.
Protection function: The controller has functions such as overcharge protection, over discharge protection, short circuit protection, overload protection, etc., to protect the safety of the photovoltaic street light system and battery.
Communication function: Modern photovoltaic street light controllers usually have communication functions, which can communicate with monitoring systems or backend management systems through wired or wireless means to achieve remote monitoring and management.
In summary, the photovoltaic street light controller achieves an efficient, stable, and safe lighting system through intelligent control of photovoltaic panels, batteries, and street lights. Its working principle is based on technologies such as maximum power point tracking, charge and discharge management, light control, and timing control. It also has multiple protection and communication functions to meet the needs of different application scenarios.
