Rapid shutdown is an electrical safety requirement set for solar panel systems by the National Electrical Code (NEC). Simply put, it provides a way to quickly de-energize a rooftop solar panel system. The National Fire Protection Association (NFPA) wrote rapid shutdown requirements into the NEC to keep first responders safe.
Solar rapid shutdown refers to the ability, mandated by regulation, to easily shut down a solar panel system in case of an emergency. Rapid shutdown regulations were first implemented in 2014 as a safety precaution by the National Electrical Code (NEC), offering a fast and effective way of cutting off the electricity running through the system.
1) The 18Kpv can do rapid shutdown out of the box using the integrated Rapid Shutdown Initiator. When triggered, the inverter will shut down the AC output and the PV (Shutdown of the PV requires a Sunspec Compliant RSD receiver on the PV panels.) 2) A remote Initiator can be installed on the 18Kpv.
Section 690.12 of the 2020 National Electrical Code (NEC 2020) covers rapid shutdown requirements and represents a vitally important safety requirement for solar PV systems.

6 FAQs about [Solar photovoltaic panels are remotely shut down]
Do rooftop solar panels need a rapid shutdown system?
You are required by law to have a rapid shutdown system installed with any new rooftop solar panel installation. All reputable microinverters and power optimizers have rapid shutdown capabilities, as well as some string inverters. The rules governing rapid shutdown are laid out in the National Electrical Code.
What is solar rapid shutdown?
Solar rapid shutdown refers to the ability, mandated by regulation, to easily shut down a solar panel system in case of an emergency. Rapid shutdown regulations were first implemented in 2014 as a safety precaution by the National Electrical Code (NEC), offering a fast and effective way of cutting off the electricity running through the system.
Why are rapid shutdown devices important for solar photovoltaic systems?
In installations where the equipment, such as inverters or modules, already includes rapid shutdown features, the system can automatically deactivate in the event of an emergency or maintenance situation. In conclusion, rapid shutdown devices play a crucial role in ensuring the safety and reliability of solar photovoltaic (PV) systems.
Do solar panels need a shutdown boundary?
Newer regulation, NEC 2017, takes these standards a step further: the more recent code decreased the shutdown boundary requirements to include any conductors within 1 foot of your solar array or more than 3 feet of length inside your home.
Can a solar panel system be de-energized if a home catches on fire?
Hopefully, your home never catches on fire, and you don't even have to worry about rapid shutdown functionality – but if it does, firefighters can use rapid shutdown solutions to de-energize your solar panel system just in case they need to go up on your roof.
How many rapid shutdown switches can a PV system have?
The new iteration of the NEC also notes that there can still be up to six rapid shutdown switches on a single service; however, if a PV system must have a single RSD dedicated to it, then those six RSDs would imply a connection to six distinct PV systems.
