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.
Due to its compact, high-performance design, it is capable of managing a continuous DC current of 16 amperes and delivering up to 427 VA of peak output power, supporting high-power solar panels up to 600 W.
“We have carefully vetted the Enphase IQ9N-3P Microinverter and are excited to install it on many commercial projects over the next several years,” said Jon Wedel, co-owner and vice president of commercial at Namaste Solar, in a statement. “Because of the new 480 V solution, we can pursue many more straightforward applications and install these systems more efficiently. The U.S. manufacturing and domestic content qualification makes navigating the current market much easier while delivering a top-quality, dependable solution for our client base.”
The new microinverter meets UL 1741-SB and IEEE 1547-2018 grid compliance standards and features rapid shutdown, phase balancing, voltage/frequency ride-through, and loss-of-phase detection for grid safety and system reliability.
Drew Collom, co-founder of Quality Solar, added, “GaN technology and three-phase support make the IQ9N-3P Commercial Microinverter a strong fit for modern commercial rooftops. With production in the United States and domestic content alignment, we can design more efficient systems, meet federal sourcing requirements, and scale projects over time without costly redesigns.”
