Industry Leaders Unite in Support of Rapid Shutdown Standard

SAN JOSE, Calif., May 13, 2020—The SunSpec Alliance is pleased to report that six additional SunSpec members have announced products and services supporting the SunSpec Communication Signal for Rapid Shutdown standard, bringing the size of the SunSpec Rapid Shutdown ecosystem to 12 companies.

SunSpec Rapid Shutdown ecosystem participants include balance-of-system suppliers with stand-alone PV module-level initiators and transmitter products (APsystems, JMTHY, Midnite Solar, Stäubli and ZERUN); inverter manufacturers with integrated transmitters (Fronius, Ginlong and SMA); semiconductor companies (Texas Instruments) and SunSpec Authorized Testing Laboratories (CSA, Intertek and UL).

“With the addition of these influential companies, the SunSpec Rapid Shutdown ecosystem is stronger than ever and has increased capacity to promote safety and standardization across the distributed energy landscape,” said Tom Tansy, chairman of the SunSpec Alliance. “As more solutions come to market to help integrators comply with rapid shutdown requirements, these leaders are ensuring safe deployment of solar and storage systems in the U.S.”

Since it launched the SunSpec Communication Signal for Rapid Shutdown standard, the SunSpec Alliance has continued to hone and simplify the SunSpec Certification process and interoperability program. Important advancements include supporting the test requirements with the UL 1741 standard and mobilizing a co-operative marketing and educational program to raise the visibility and awareness of SunSpec Rapid Shutdown solutions. SunSpec has also recently enhanced its local support capabilities for manufacturing partners in Asia.

With this ecosystem expansion, solar professionals have more choices and a wider range of cost-effective, standardized solutions to comply with rapid shutdown requirements.
