RAPID SHUTDOWN

FACT SHEET

SUNSPEC RAPID SHUTDOWN CERTIFICATION PROGRAM

MEETING A MARKET MANDATE FOR SOLAR SAFETY

PV module-level power control

and safety (“rapid shutdown”)

is required in 24 states starting

in January 2019

2017 Edition

Requirement established by National
Electrical Code (NEC ) 2017.

Goal to protect firefighters and
consumers who need to interact
with a PV system.

NEC 2017 is an “inclusive” standard,
meaning it applies to all manufacturers
and equipment types covered by
the standard.

The mandate aects millions of
PV panels and all solar inverters.

Common term: Rapid Shutdown
NEC code term: PV Hazard Control

SunSpec Alliance global

leaders have developed an

open standard rapid shutdown

communication solution

SunSpec
Communication
Signal for Rapid

Shutdown

Functional

Specification

29 companies worked together to
create the solution, each of which
contributed unique ideas and
intellectual property.

The solution benefits all consumers
by increasing safety of PV systems
and vendors by establishing a
Plug-and-Play standard for any solar
panel and inverter combination.

Products complying to the standard are
now available from world-class vendors.

SunSpec has launched a

Rapid Shutdown

Certification Program

Certification program communicates
that system components work well with
each other and have been tested to
NEC 2017 requirements.

SunSpec Alliance oers Communication
Signal for Rapid Shutdown certification
for third party Independent Testing
Laboratories, including Nationally
Recognized Testing Laboratories.

The first SunSpec Certified Test Labs
were announced in October 2018.
