Abstract
A rapid shutdown device for rapidly de-energizing a photovoltaic module system is disclosed. The rapid shutdown device includes power lines connected to a photovoltaic string of modules on a roof of a structure. A high voltage switch on a first power line is disconnected when the high voltage switch is open. The rapid shutdown device includes a gate drive circuit that receives an electronic photovoltaic string status signal associated with an operating status of the photovoltaic string. The date drive circuit may determine that the operating status indicates the presence of a hazard based on the electronic photovoltaic string status signal. Based on the presence of the hazard, the rapid shutdown device generates a high voltage switch command signal to cause the high voltage switch to open to disconnect the photovoltaic string from an electrical connection to a grid power supply, thereby enhancing protection of the string and safety for responders.
