UL Solutions Inc. has introduced the first industry-wide cybersecurity certification program for distributed energy resources and inverter-based devices. The initiative established a common cybersecurity baseline for microgrids, batteries, hydrogen systems and electric vehicle infrastructure. It provided manufacturers, utilities, regulators and grid operators with a unified framework to evaluate and certify device-level cyber protections. Certification testing follows UL 2941, the Standard for Cybersecurity of Distributed Energy and Inverter-Based Resources, which defines requirements for access management, cryptography, data handling and documentation. The program complements existing safety testing under UL 1741 for inverters, converters, controllers and interconnection equipment. It responds to rising cyber risks linked to integrating legacy grid assets with internet-connected technologies. The framework builds on 2019 test cases from the U.S. Department of Energy’s National Laboratory of the Rockies.
