Advanced Inverter Evaluation

The ANSI/UL 1741 standard has incorporated a Supplement A (SA) to validate compliance for “grid support utility interactive inverters," and a Supplement B (SB) to validate compliance with grid protection and grid support functions. To demonstrate compliance with ANSI/UL 1741 Inverter certification can be broken down into two options for manufacturers: Utility Interactive Inverters and Grid Support Utility Interactive Inverters.

Intertek’s Advanced Inverter Evaluation: UL 1741 Supplement A & B used in conjunction with IEEE 1547 and IEEE 1547.1-2020 fact sheet provides guidance on the regulations and testing needed to comply with certification requirements within ANSI/UL 1741 Supplement A & B, and IEEE 1547.1-2020.
