Abstract
A method for starting a photovoltaic rapid shutdown system, an application apparatus and a system are provided. In this method, the inverter system controls a voltage of a direct current bus in the photovoltaic rapid shutdown system. The photovoltaic module breaker makes determination based on a detected output voltage of the photovoltaic module breaker. In a case that the change characteristics of the voltage of the direct current bus connected to the photovoltaic module breaker meets the predetermined turn-on condition, the photovoltaic module breaker controls itself to be turned on. Therefore, the photovoltaic module breaker can determine whether the photovoltaic module breaker receives a turn-on signal only based on its own voltage acquisition device without an additional receiving apparatus.
