Enphase Energy Reinforces U.S. Manufacturing Across Residential, Commercial, and AI Infrastructure

IQ Microinverters, IQ Batteries, and the upcoming IQ Solid-State Transformer platform bring trusted U.S. power electronics to homes, businesses, and AI data centers

FREMONT, Calif., Aug. 04, 2026 (GLOBE NEWSWIRE) -- Enphase Energy, Inc. (NASDAQ: ENPH), a global energy technology company, today reinforced its commitment to designing and manufacturing critical power electronics in the United States, spanning residential and commercial solar and battery systems and next-generation power infrastructure for AI data centers. Founded and headquartered in the United States, Enphase produces IQ^® Microinverters and IQ^® Batteries at manufacturing facilities in South Carolina and Texas and expects to produce its upcoming IQ^® Solid-State Transformer (IQ^® SST) platform for AI data centers in the United States.

Power electronics are the intelligence layer of modern energy infrastructure, determining how electricity is converted, controlled, and secured. Their strategic importance is increasing as homes and businesses electrify and AI data centers emerge as some of the largest and most demanding loads on the grid. Recent action by the Federal Communications Commission underscores the growing national focus on the security of power inverters and other connected energy technologies. Enphase combines U.S.-based design with domestic manufacturing options to deliver trusted, resilient power systems for critical energy infrastructure.

"The inverter is the brain of the modern grid, and Americans deserve to know theirs can be trusted," said Raghu Belur, co-founder and chief product officer at Enphase Energy. "Securing the power electronics on homes and businesses across the country has never mattered more. As AI data centers scale into some of the largest loads on the grid, securing the power behind them becomes even more critical. Manufacturing these systems in the United States strengthens energy security, supply chain resilience, and the trusted infrastructure the country increasingly depends on."

For residential and commercial solar and battery systems, Enphase offers U.S.-produced IQ Microinverters and IQ Batteries with a “DOM” suffix. These products can help eligible projects meet applicable U.S. sourcing requirements and qualify for domestic content bonus tax credits. Select IQ Microinverters meet Buy American Act and Build America, Buy America standards, and certain Enphase products may be deemed “FEOC compliant” for purposes of 26 U.S.C. Section 7701(a)(51) using IRS Notice 2025-08 for rooftop solar and distributed BESS. Enphase also expects to produce the power electronics for its upcoming DC-based IQ^® Bidirectional EV Charger in the United States. Together, these options strengthen Enphase’s position across residential, commercial, plug-in solar, and electric mobility markets. Legal and tax advisors should be consulted to confirm eligibility.

IQ SST extends the Enphase platform into AI data centers and other high-power applications. Enphase expects to produce IQ SST at U.S. manufacturing facilities, creating a domestic, modular, and scalable alternative for a critical layer of AI infrastructure. The GaN-based platform is designed to convert medium-voltage AC power directly to the 800 V DC power required by modern AI compute systems, with distributed control, software intelligence, and redundancy.

At approximately 4 kW per IQ SST power module, a 1 GW AI data center could require roughly 250,000 power modules without factoring in redundancy requirements. As an illustration of potential scale, 10 GW of aggregate deployment would correspond to approximately 2.5 million IQ SST power modules. Enphase brings substantial experience manufacturing distributed power electronics at scale, having shipped approximately 89.4 million microinverters cumulatively, including approximately 5.5 million microinverters from the United States. in 2025. This experience in distributed architecture, quality systems, and automated manufacturing provides a strong foundation for scaling the modular IQ SST platform.

Enphase serves customers in more than 165 countries. Its U.S. manufacturing expansion is designed to support U.S. market requirements, national policy priorities, and critical infrastructure needs. It does not change the company’s commitment to Europe, Australia, India, and other international markets. Enphase will continue to develop region-specific products for local grids, regulations, and customer needs, backed by consistent standards for safety, quality, reliability, cybersecurity, and service.
