SunSpec Rapid Shutdown Certification

Only the “SunSpec Certified” mark warrants verification of a complete and successful implementation of the SunSpec Communication Signal for Rapid Shutdown Functional Specification.

A manufacturer’s or other 3rd party’s declaration of “SunSpec compliance” or “SunSpec compatibility”  is not equivalent to a SunSpec issued certificate.

The SunSpec Certified program for Rapid Shutdown verifies compliance to the SunSpec Communication Signal for Rapid Shutdown Functional Specification to meet the requirement established by National Electrical Code (NEC) 2017. PV module-level power control and safety (“rapid shutdown”) is required in 24 states starting in January 2019 and will affect millions of PV panels and all solar inverters. This standard is tested using UL 1741 SA criteria. Please visit the SunSpec Rapid Shutdown Program.

SunSpec Rapid Shutdown Certification Testing must be conducted by one of our Authorized Test Labs (ATLs). Each test lab is free to determine its own testing and fee structures. Once a Certification Application and payment have been submitted to SunSpec a shared space is opened where your ATL test engineer can submit test results for our analysis.  SunSpec evaluates the test results for compliance to SunSpec Communication Signal for Rapid Shutdown Functional Specification and theSunSpec Communication Signal for Rapid Shutdown Test Specification and then awards the Certificate!
