Enphase Energy shipping IQ9N-3P Commercial Microinverters across U.S.
Enphase Energy Inc. has announced that it began production shipments of its IQ9N-3P Commercial Microinverter in the U.S. in December 2025.
Onshoring manufacturing of the microinverter allows Fresno, California-based Enphase to comply with the Trump administration’s Foreign Entities of Concern (FEOC) restrictions for commercial solar projects.
The product helps simplify system design, lowers installation and balance of system (BOS) costs, and improves system efficiency for commercial projects up to 480 V, according to company officials. Using gallium nitride (GaN) technology instead of silicon for power conversion, the product boasts an efficiency number of up to 97.5%.
“The IQ9N-3P Commercial Microinverter brings Enphase’s panel-level architecture to the 480 V commercial market with a simpler, more efficient design powered by GaN,” says Aaron Gordon, senior VP and GM of the systems business unit at Enphase. “By manufacturing this product in the United States, we’re helping commercial projects meet domestic content requirements while delivering the reliability, flexibility, and long-term value Enphase is known for.”
Meeting microinverter compliance standards
The IQ9N-3P Microinverter has been “carefully vetted” for production, shipping, and installation in the U.S. market, according to Jon Wedel, co-owner and vice president of commercial at Colorado-based cooperative Namaste Solar.
“We have carefully vetted the Enphase IQ9N-3P Microinverter and are excited to install it on many commercial projects over the next several years,” Wedel says. “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.”
Boasting rapid shutdown as well as phase balancing and other features, the microinverter meets “rigorous” compliance standards for electrical products, including UL 1741-SB and IEEE 1547-2018. The products are compatible for deployment on both small (less than 100 kW) systems and large systems and are scalable over time, the company says.
“GaN technology and three-phase support make the IQ9N-3P Commercial Microinverter a strong fit for modern commercial rooftops,” says Drew Collom, co-founder of Quality Solar. “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.”
Enphase systems may also help reduce operational costs for system owners through easy replacement support and per-panel monitoring through the Enphase App, representatives say.
The IQ9N-3P must be connected to the IQ Gateway Commercial Pro monitoring system to work properly, and set up through the company’s Enphase Installer app.
