Scaling DER Communications in California: Protocol Certification Requirements
Learn the Key Industry Certifications Required by CA Rule 21
Updated January 2023!
Given the variety of interests and opinions about what testing and certifications advance the efficiency and interoperability of deploying DER communications infrastructure, the landscape of standards and certifications can be confusing. This paper identifies the current, future, required, and optional certifications relevant to implementing CA Rule 21 for Smart Inverter communications. You’ll read about:
- UL 1741SA Certification
- IEEE 1547-2003
- SunSpec IEEE 2030.5 DER Certification
- IEEE1547-2018 Interoperability Certification
QualityLogic is contributing this White Paper to the DER integration efforts because of our role in the industry. Our mission is to accelerate interoperable communities by standardizing communications between grid operators and DER assets (both DR and DER), between utilities and aggregators, between aggregators and DER assets and even between DER assets.
