What does Rapid Shutdown mean?
Rapid shutdown is a PV safety function that reduces energized conductors in or around a solar array to safer voltage levels after a shutdown is initiated.
Why does Rapid Shutdown matter for solar safety and code compliance?
This term matters because PV systems must be safe for installers, owners, service teams, and first responders. Safety terminology may not be flashy, but it is what keeps the flashy parts from becoming sparky parts.
