Enphase Energy, Inc. (NASDAQ:ENPH), a global energy technology company and the world's leading supplier of microinverter-based solar and battery systems, today opened U.S. pre-orders for the new IQ9N-3P™ Commercial Microinverter. This is Enphase's first microinverter powered by advanced gallium nitride (GaN) technology and designed for three-phase 480Y/277 V (wye) grid configurations, without using external transformers.
The IQ9N-3P Commercial Microinverter simplifies design complexity, lowers installation and balance of system costs, and improves system efficiency for 480 V commercial projects. The GaN technology replaces traditional silicon-based components from previous product generations to enable faster switching, cooler operation, enhanced reliability, and an industry-leading efficiency of 97.5%. Its compact, high-performance design can manage a continuous DC current of 16 amperes and deliver up to 427 VA of peak output power, supporting high-power solar panels up to 600 W.
The new microinverter meets rigorous grid compliance standards, including UL 1741-SB and IEEE 1547-2018, and features rapid shutdown, phase balancing, voltage/frequency ride-through, and loss-of-phase detection for grid safety and system reliability. Additionally, by converting direct current (DC) to alternating current (AC) at each panel, Enphase microinverter systems avoid the long high-voltage DC runs found in traditional centralized ("string") designs, offering a safe, all-AC architecture on the roof.
Enphase IQ9N-3P Commercial Microinverters can be deployed on small systems (less than 100 kW) or large systems (hundreds of kW) and provide the flexibility to start small and expand the system size over time without any redesign. Enphase microinverter technology also enables increased energy production at the panel level under shading and uneven roof conditions, making the product ideal for commercial rooftops with HVAC obstructions, skylights, and multi-tenant layouts. Enphase microinverter systems can reduce long-term operational costs for asset owners by eliminating single points of failure in the installation, providing easy replacement support, and improving fleet visibility with per-panel monitoring via the Enphase® App.
The IQ9N-3P Commercial Microinverter will be made with domestic content in U.S. manufacturing facilities, helping solar projects meet key federal requirements and qualify for current domestic content bonus tax credits. This will also allow the commercial microinverters to comply with the current Buy America Act and Build America, Buy America Act, enabling the products to be used in federal infrastructure projects.
