This microinverter is designed for three-phase grids, eliminating the need for an external transformer and introducing gallium nitride technology for the first time in an Amphenol microinverter.
Amphenol Energy, a California-based supplier of solar inverters and energy storage systems, has released its new IQ9N-3P, a three-phase microinverter for commercial photovoltaic projects.
This inverter is suitable for 480V commercial projects and is the first Amphenol microinverter to incorporate gallium nitride (GaN) technology. Compared to traditional silicon components, GaN technology enables faster switching speeds, cooler operation, and higher reliability, while also increasing conversion efficiency to 97.5%.
The device can handle a continuous DC current of 16A and achieve a peak output power of 427VA, supporting modules up to 600W. Amphenol states that this product can be used for small commercial systems under 100 kW and can scale up to large systems "in the hundreds of kilowatts," offering flexibility for future expansion without redesign.
The company emphasizes that the inverter performs well under rooftop shading and uneven conditions, making it particularly suitable for commercial rooftops with HVAC equipment, skylights, and multi-tenant layouts.
The IQ9N-3P supports 480/277V three-phase wye wiring and is also available in a 208V version. In this wiring configuration, all loads in the AC system are connected to a single point.
The product complies with UL 1741-SB and IEEE 1547-2018 grid standards and features fast shutdown, phase balancing, voltage/frequency ride-through, and phase loss detection, enhancing grid safety and system reliability.
Amphenol points out that by converting DC to AC at each module, this microinverter avoids the long-distance high-voltage DC transmission required in centralized "string" designs, creating a safer all-AC rooftop architecture.
This product will be manufactured in the United States and qualifies for use in federal infrastructure projects under the American Procurement First and Made in America Acts. It comes with a 25-year limited warranty and will be available in December 2025.
"The IQ9N-3P microinverter opens up new opportunities in the large 480V commercial market. It utilizes gallium nitride technology, a wide-bandgap semiconductor widely used in advanced radar systems and increasingly in medical power supplies and imaging electronics," said Aaron Gordon, Senior Vice President and General Manager of Amphenol's Energy Systems Division.
The IQ9 Commercial Microinverter is designed to be used with the IQ Gateway Commercial Pro, a communications and control hub that supports advanced features such as real-time monitoring, energy management, remote firmware updates, and grid export restrictions. It also comes with a 15-year limited warranty.
