Sep 28, 2021 · An electronic document associated with a UL Standard for Safety or Outline of Investigation, and issued by UL to propose: A revision of a single or multiple requirement(s). A complete new edition of an existing Standard or Outline.

Mar 6, 2023 · The tests that an “advanced inverter” must pass to receive UL 1741 certification were designed to meet or exceed the interconnection requirements set by the IEEE 1547-2018 standard and include additional tests for fire and electrical safety.

May 19, 2023 · UL 1741 Inverters, Converters, Controllers and Interconnection System Equipment for Use With Distributed Energy Resources

Aug 11, 2022 · Our inverters are fully UL 1741 SA certified. You can connect them to the grid right out of the box and enable your inverter-based device to remain compliant with the latest certifications, including UL 2035, which includes enhanced performance requirements from inverter-based devices.

UL Solutions tests power inverters, converters and power plant controllers (PPC) to the requirements of all key international standards, including: UL 1741, the standard for Inverters, Converters, Controllers and Interconnection System Equipment for use with Distributed Energy Resources (DER)

UL1741 is going to be harmonized with IEEE 1547, Interconnecting Distributed Resources with Electric Power Systems and IEEE P1547.1 once it is published. This direct reference will maximize acceptance and interpretation consistency.
