Enphase Launches GaN Microinverters, Targets 480V Commercial Market

  • Enphase Energy began shipping its IQ9N-3P™ Commercial Microinverter in the United States in late December 2025.
  • The IQ9N-3P utilizes gallium nitride (GaN) technology, marking Enphase’s first microinverter with this feature.
  • The microinverter is manufactured in the U.S. to meet domestic content requirements and Foreign Entity of Concern (FEOC) compliance.
  • The product is designed for three-phase 480Y/277 V (wye) grid configurations and boasts up to 97.5% efficiency.

Enphase’s entry into the 480V commercial market with a GaN-powered microinverter represents a strategic expansion beyond its traditional residential and smaller commercial focus. The domestic manufacturing and compliance aspects are crucial given current US government incentives and supply chain concerns. This move positions Enphase to capitalize on the growing demand for commercial solar installations, particularly those requiring adherence to Buy America Act and Build America, Buy America Act requirements.

Market Adoption
The pace at which commercial installers integrate the IQ9N-3P into projects will determine the initial success and inform Enphase’s production ramp.
FEOC Compliance
Continued scrutiny of FEOC compliance and potential shifts in government policy could impact the microinverter’s eligibility for tax credits and project approvals.
Competitive Response
Competitors may accelerate their own GaN microinverter development or introduce alternative solutions, potentially eroding Enphase’s first-mover advantage.
