What is PV-OFF™?
A module-level 0V rapid shutdown state; it supports electrical safety, inspection, or code-compliant system operation.

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.
