Application: Photovoltaic assembly shutoff device, inverter, and photovoltaic quick shutoff system and starting method therefor (Patent ID: US20240195179A1)
The patent filed by Sungrow Power Supply Co Ltd describes a shutdown device for a photovoltaic module, an inverter, a rapid shutdown system, and a method for starting the rapid shutdown system. The method involves switching the shutdown device into a mode of unlimited output after initially starting, sampling an electrical parameter at the output terminal, and determining if it meets a preset starting condition. If the condition is met, the shutdown device operates in the mode of unlimited output. The system includes various components such as a switch unit, starting voltage module, driving circuit, processor, bypass diode, and parameter sampling unit to facilitate the method.
Furthermore, the patent outlines specific claims related to the method for starting a rapid shutdown system, including detecting disturbances in electrical parameters, such as voltage and current, to ensure proper functioning of the shutdown devices. The inverter described in the patent includes a sampling circuit, inverter circuit, signal processing circuit, and controller to control the connection to the grid and apply disturbances. The rapid shutdown system consists of the inverter, photovoltaic strings, and multiple shutdown devices, each comprising various components like a switch unit, starting voltage module, driving circuit, processor, bypass diode, and parameter sampling unit. These components work together to ensure the efficient operation of the rapid shutdown system in photovoltaic installations.
