Midnite Solar Rooftop Rapid Shutdown System

Tue, 04/08/2014 - 20:22
This system from our friends at Midnite Solar allows solar energy professionals to easily comply with the new NEC 2014 requirement, Article 690.12, that requires a fast and easy way for firefighters to de-energize all rooftop solar photovoltaic (solar electric) arrays from a singe location within 10 seconds. These new Codes are somewhat controversial because of the cost they add to every new rooftop solar electric array, but are welcomed by many emergency responders who find themselves climbing around rooftops fighting fires. They have enough problems up there without worrying about electrocution by solar power. You can check out Midnite Solar's rapid rooftop shutdown system here: And watch our workshop calendar online for upcoming, IREC / ISPQ / NABCEP accredited classes on renewable energy systems and firefighter safety. Both online and in-person classes are available for your required annual CEUs. This video is not an ad. Midnite is one of our educational sponsors, and you can read our policy on that here: They send us and a whole bunch of other folks brand new stuff to test and abuse and try to break, and we tell them what we think, good or bad. Stay safe.
