Enphase Begins U.S. Shipments of GaN-Powered Commercial Microinverter

Enphase Energy, Inc. announced it has begun shipping its IQ9N-3P™ Commercial Microinverter across the United States, with initial deliveries starting in late December 2025.  It is Enphase’s first gallium nitride (GaN)–powered microinverter, designed for three-phase 480Y/277 V (wye) grid configurations without the need for external transformers.  The IQ9N-3P Commercial Microinverter is manufactured in the United States and complies with domestic content requirements and Foreign Entity of Concern (FEOC) rules for eligible commercial solar projects.  The product helps simplify system design, lower installation and balance of system costs, and improve system efficiency for 480 V commercial projects. By utilizing GaN technology in the power conversion stage instead of silicon, it enables greater performance and reliability.
