The basic components of a photovoltaic street light controller mainly include the following parts:
Power module: used to convert the direct current generated by photovoltaic panels into stable direct current, providing working power for the entire controller.
Charging control module: mainly responsible for charging management of the battery (rechargeable battery), controlling the charging current and voltage based on the battery’s state of charge and charging requirements to ensure that the battery is fully charged and not overcharged.
Discharge control module: used to control the discharge process of the battery, adjust the discharge current and voltage according to the brightness requirements of the street lamp and the battery level, and achieve brightness adjustment of the street lamp.
Protection module: including overcharge protection, over discharge protection, short circuit protection, overload protection and other functions to ensure the safe and reliable operation of the photovoltaic street light system.
Constant current control module: ensures stable brightness of street lamps, unaffected by battery level and external environment.
Communication module: used to communicate with the upper computer or other devices to achieve remote monitoring and management.
Other auxiliary modules, such as temperature sensors, light sensors, etc., are used to automatically adjust the working status of street lamps according to environmental conditions. In short, the photovoltaic street lamp controller is an intelligent control system that integrates charging control, discharging control, protection function, constant current control, and communication function. It can effectively improve the performance and reliability of the photovoltaic street lamp system, and provide better services for urban road lighting.
