Enphase Energy (ENPH) jumped 13.82% to $42.66 after the company opened U.S. pre-orders for its new commercial microinverter. The stock climbed from early lows near $37.50 and reached session highs above $42.50. The move followed stronger attention around Enphase’s expanded commercial solar product lineup.
Enphase Expands Commercial Solar Portfolio
Enphase introduced the IQ9S-3P Commercial Microinverter for the U.S. 480 V three-phase market. The product uses gallium nitride technology and supports high-wattage solar panels up to 770 W. It also connects directly to 480Y/277 V grid systems without external transformers.
The new microinverter expands Enphase’s commercial portfolio alongside the recently launched IQ9N-3P model. Together, both products target larger solar projects that need higher output and simpler system design. The pre-order window also helps customers reserve equipment before federal tax credit deadlines.
IQ9S-3P delivers up to 548 VA of continuous output power. It also supports 18 A of continuous DC current for higher-capacity solar modules. As a result, Enphase can serve commercial rooftops using 600 W to 770 W panels.
GaN Technology Strengthens Product Performance
Enphase built the IQ9S-3P with advanced GaN technology to improve power handling and operating efficiency. The product reaches a CEC weighted efficiency of 97.5%. It also supports cooler operation, which can help performance across demanding commercial sites.
The microinverter design converts DC power to AC power at each solar panel. This structure removes long high-voltage DC runs used in many string inverter systems. Enphase continues to push its all-AC rooftop architecture into larger commercial projects.
The product also includes rapid shutdown, phase balancing, and voltage ride-through features. It meets UL 1741-SB and IEEE 1547-2018 grid compliance standards. These features support safety, grid reliability, and system monitoring through the Enphase App.
ENPH Stock Gains as Shipments Approach
ENPH stock gained sharply as the product launch added fresh momentum to the company’s commercial solar story. The move came as traders reacted to stronger product positioning and broader market reach. The stock held near its session highs after the early rally.
Enphase expects production shipments of IQ9S-3P Commercial Microinverters to begin in June 2026. The product carries a 25-year limited warranty, while the IQ Gateway Commercial Pro carries a 15-year warranty. The gateway supports monitoring, firmware updates, export limiting, and energy management.
The company also said certain U.S.-made products may meet FEOC compliance standards under IRS guidance. Eligible projects may also qualify for domestic content bonus tax credits. The launch gives Enphase a stronger role in high-power commercial solar projects.
