c) Enphase Energy System Shut down as Rapid Shutdown for PV
As per the NEC requirement every PV installation should have a visible and single point of disconnection
which will shut down the PV arrays and deenergize the cables to make it safe for firefighters in the event
of an emergency and also to help electrical technicians to carry out maintenance activities safely.
The Enphase System Shutdown switch provides the functionality of Rapid shutdown as mandated by
NEC when it is used with IQ System Controller 2 which has a IQ8 micro inverter connected to it. For more
information on Rapid shutdown please refer to the Rapid Shutdown FAQ
