PV Rapid Shutdown Systems (QIJS) include assessments of the complete system to fulfill the rapid shutdown function. Equipment Certified (Listed) under QHYZ other than AC modules needs to be further evaluated to form an overall PV rapid shutdown system. When multiple pieces of PV rapid shutdown equipment are used in an overall system.

Rapid shutdown system

Rapid Shutdown Any time a Rapid Shutdown event is triggered, a set of normally-closed terminals on a Rapid Shutdown Initiator will open. When the SkyBox Rapid Shutdown input terminals sense this, the SkyBox will shut down accordingly. When this occurs, an Alert message will appear in the SYSTEM NOTIFICATION screen. (See pages 3 and 14.).
