Fast Shutdown refers to a safety feature implemented in solar power systems that allows for the rapid deactivation of the system in the event of an emergency or when maintenance is required. This feature is especially important for photovoltaic (PV) systems, where solar panels generate electricity even when disconnected from the grid. Fast Shutdown ensures that all high-voltage components are quickly de-energized to protect both first responders and maintenance personnel from electrical hazards.
