Midnite Solar Rapid Shutdown System

The new 2014 National Electrical Code (NEC 2014) contains a somewhat controversial new rule intended to protect firefighters who have to work on rooftops where solar photovoltaic (PV) systems are installed - Article 690.12, Rapid Shutdown of PV Systems on Buildings.

It requires a shutdown system with which emergency responders can de-energize the entire solar array within 10 seconds from a clearly-marked central switch before venturing onto a rooftop for firefighting.
