Enphase Energy has reaffirmed its commitment to designing and manufacturing critical power electronics in the United States, expanding domestic production across residential and commercial solar, battery energy storage systems (BESS), and next-generation power infrastructure for artificial intelligence (AI) data centers.

The company said it currently manufactures its IQ® Microinverters and IQ® Batteries at facilities in South Carolina and Texas, and plans to manufacture its upcoming IQ® Solid-State Transformer (IQ® SST) platform for AI data centers in the United States.

According to Enphase, the move supports U.S. energy security, strengthens domestic supply chains, and addresses the increasing importance of secure power electronics as electricity demand rises from electrification and the rapid growth of AI data centers.

The company noted that its U.S.-manufactured IQ Microinverters and IQ Batteries, identified with a “DOM” suffix, can help eligible solar and storage projects meet domestic sourcing requirements and qualify for U.S. domestic content tax incentives. Select products also comply with Buy American Act and Build America, Buy America requirements, while certain products may qualify as Foreign Entity of Concern (FEOC)-compliant for rooftop solar and distributed battery energy storage applications.

Enphase also plans to manufacture the power electronics for its forthcoming IQ® Bidirectional EV Charger in the United States, further expanding its domestic clean energy product portfolio.

The company’s upcoming IQ SST platform is designed for AI data centers and other high-power applications. Based on gallium nitride (GaN) technology, the platform will convert medium-voltage alternating current (AC) directly into 800 V direct current (DC) required by modern AI computing infrastructure through a modular architecture featuring distributed control, software intelligence, and built-in redundancy.

Enphase estimates that a 1 GW AI data center would require approximately 250,000 IQ SST power modules, excluding redundancy, while 10 GW of deployments could require around 2.5 million modules, highlighting the significant scale of future demand.

The company said its manufacturing experience provides a strong foundation for scaling the platform, having shipped approximately 89.4 million microinverters globally, including 5.5 million units manufactured in the United States during 2025.

While expanding U.S. manufacturing capabilities, Enphase emphasized that it remains committed to serving international markets, including Europe, Australia, India, and other regions, where it will continue developing products tailored to local grid requirements, regulations, and customer needs.
