Update On IEEE 1547.1 Adoption

A lot has happened since our last webinar in December on this topic! There have been significant changes in the adoption timeline and a lot of progress has been made on UL 1741SB.

Mandating the inclusion of a local, standard communications interface promises a quantum leap in making DERs easy to manage for grid operators. Because of the upcoming UL 1741 SB Revision (clarifying testing in IEEE 1547.1-2020), the actual requirement for certification is still in regulatory negotiation. The webinar will provide the latest updates on timelines for UL 1741 SB approval and our guesstimates on actual regulatory requirements.

Whether UL 1741 SB certification is required by January 1, 2022, or September 1, 2022, there are more than 50 vendors with hundreds of inverter families likely to seek UL 1741 SB certification in the next year or so. At about 10 weeks of testing each, there is a potential for an expensive industry bottleneck in certifications. QualityLogic’s 1547.1 test tools are designed to reduce the time (and costs) of testing and improve the consistency of test results. This webinar will provide an update on the progress we are making on the tools, the labs using them, and new additions of SunSpec Modbus support and Type testing using IEEE 2030.5 or SunSpec Modbus messaging.


JUNE 17, 2021: 8:00 a.m. to 9:00 a.m. Pacific Time (US)

The one-hour webinar will cover:

  • IEEE 1547 Background
  • The Interop and Type Testing requirements in IEEE 1547-2018 and 1547.1-2020
  • UL 1741 SB revisions and certification timeline
  • Challenges in testing and certifying the Interop and Type requirements
  • QualityLogic’s test tools for validating IEEE 1547 Interop and Type Testing Conformance
  • Test system architecture and features
  • Demonstration of QualityLogic 1547.1 Test Tool with Inverter and Lab Equipment
  • Questions and Answers

This webinar is aimed at technical managers and implementers who need to understand the new IEEE 1547 Interop requirements, those tasked with implementing them in their products, and those responsible for testing products to ensure conformance with the standard.
