In 2017, a revised version of the U.S. National Electrical Code (NEC 2017) comes into effect, which then requires module-level rapid shutdown. SunSpec Alliance reacted on that and drafted specifications for the communication signal supporting module-level rapid shutdown (Communication Signal for Rapid Shutdown, SunSpec Interoperability Specification).
In total compliance with these specifications, SunSniffer developed a sensor, which not only provides the special and unique module-level monitoring system, including module-level temperature measurement, analysis via artificial intelligence and a simulation engine, but additionally is able to rapidly shut the system down according to the requirements of NEC 2017.
LEONI and QC Solar know the revolutionizing SunSniffer technology and together with SunSniffer developed the respective junction boxes with the embedded sensor. Market release will be December 2016, just on time for the NEC 2017 regulations.
