The component-level rapid shutdown device is an important component for protecting the safety of PV systems. By controlling the switch of current and voltage, it can quickly cut off the circuit in case of a fault in the PV system, effectively avoiding the spread of faults and the occurrence of fires. With the continuous development of technology, component-level rapid shutdown device have become one of the necessary devices for protecting the safety of PV systems.
Governments worldwide, including the European Union, the United States, and China, have implemented regulations and standards mandating the incorporation of component-level rapid shutdown devices in photovoltaic (PV) systems. These devices are crucial for the safety of firefighters and first responders. In the United States, stringent measures have been enforced to ensure the rapid disconnection of solar PV systems. The 2020 National Electrical Code (NEC) introduced revisions regarding “Rapid Shutdown” within the array boundary to address “PV hazard control systems.” Section 690.12(B)(2) outlines requirements to safeguard the well-being of first responders once the PV hazard control system is activated. Firefighters, as first responders, often encounter building fires and immediately cut off power to the building, enabling them to enter or create vents in the roof system to extinguish the fire.
