Abstract

A shutdown device for a photovoltaic module, an inverter, a rapid shutdown system, and a method for starting the rapid shutdown system are provided. The method is applied to the rapid shutdown system after each shutdown device in the rapid shutdown system initially starts. The shutdown device is switched into a mode of unlimited output in response to its success in initially starting. The shutdown device, in response to its failure to initially start or when being switched off, samples an electrical parameter at its output terminal in real time, determines whether the electrical parameter meets a preset starting condition, and switches itself on and operates in the mode of unlimited output when the electrical parameter already meets the preset starting condition.
