Enphase Delivers the New Standard for Commercial Solar
- Made in the USA
- Highest Energy Production
- Lowest Operating Cost

Domestic Content, BAA, BABA, and FEOC Compliance
With U.S.-based manufacturing, Enphase meets FEOC compliance standards and currently qualifies for IRA domestic content bonus credits—advantages many manufacturers cannot offer.
Enphase’s domestically manufactured commercial microinverters also provide solar installers with a reliable solution for federally funded projects requiring compliance with the Buy America Act and/or Build America, Buy America Act.
Optimized Energy Production Means Everyone Wins
The IQ9N-3P Microinverter is built with advanced gallium nitride (GaN) technology, replacing traditional silicon components to deliver faster switching, cooler operation, and an impressive 97.5% efficiency. Designed to support high-power modules up to 600 W, each unit handles 16 A of continuous DC current and delivers up to 427 VA of peak output power—ideal for maximizing energy harvest on commercial rooftops.
Enphase brings nearly two decades of proven reliability and brand trust, backed by a strong track record of warranty performance, and dedicated 24/7 customer service. With Enphase, system uptime is maximized—resulting in higher energy production and improved project economics.
Simplified Design, Installation, and O&M
Solar installers will appreciate the simplified system design and reduced balance-of-system costs. By converting DC to AC at the panel level, Enphase eliminates long high-voltage DC runs, offering a safe, all-AC architecture—ideal for complex layouts with HVAC units, skylights, or multi-tenant configurations.
The IQ9N-3P Commercial Microinverter is built for flexibility. The modular design allows easy expansion without redesign. Compared to traditional string inverter technology, microinverters simplify design and installation while maximizing uptime. Panel-level monitoring through the Enphase App provides installers and asset owners with granular visibility and streamlined maintenance.
The IQ9N-3P Microinverter pairs with the IQ Gateway Commercial Pro for real-time monitoring, remote updates, and advanced grid features like export limiting—all accessible through the Enphase Installer App.
Backed by a 25-year limited warranty on the microinverter and 15 years on the gateway, Enphase delivers a true three-phase commercial solution that directly addresses the challenges customers have consistently raised around commercial solar design, installation, commissioning, and O&M. The IQ9N-3P Commercial Microinverter is available for pre-order now through Greentech Renewables, with shipments expected to begin in December 2025.
Planning for Your next Commercial 480 VAC or 208 VAC Project?
Either way, Enphase has you covered. The IQ9N-3P Microinverter is building on the success of the IQ8P-3P Microinverter, which supports 208 VAC applications today. Installer adoption of Enphase’s three-phase solution has accelerated over the past two years. Customers were looking for a 480 VAC option—Enphase listened, and now it’s delivering with the IQ9N-3P Commercial Microinverter.
