Enphase Starts Texas Production of 5 MW Solid-State Transformer Platform for 800V AI Data Centers
Enphase has begun building 4 kW power modules in Texas for its IQ Solid-State Transformer platform, designed to deliver up to 5 MW per rack and convert medium-voltage utility power directly into the 800V DC architecture emerging inside AI data centers.
Why it matters: Transformer and power-conversion shortages are becoming a critical AI-data-center bottleneck, and Enphase is now physically building modules for a new 800V architecture.
Enphase Energy has moved its push into artificial-intelligence data-center infrastructure from design work into manufacturing, beginning production in Texas of power modules for its planned IQ Solid-State Transformer.
The company says 4 kW modules are now coming off a production line in Arlington, Texas and will be assembled into full-scale transformer racks for validation. Hundreds of modules can be combined into an IQ SST rack with capacity of up to 5 megawatts.
The system is being designed around one of the largest changes taking place inside AI data centers: the move toward higher-voltage DC power distribution. Enphase aims to convert medium-voltage AC directly into 800-volt DC, reducing conversion stages between the utility connection and compute rack.
Each module combines a proprietary high-frequency transformer, gallium-nitride power switching and Enphase control silicon. The architecture reflects a broader shift toward semiconductor-based, digitally controlled power systems as AI racks move toward much higher electrical densities.
Enphase has experience building distributed power electronics through its solar microinverter business and intends to apply a modular manufacturing model to data-center power. The company expects a full-system demonstration in November 2026 followed by customer pilots in 2027.
The production milestone is significant because transformer and power-conversion availability are becoming major constraints on AI data-center deployment. Whether the system reaches broad adoption will depend on validation and customer pilots, but hardware is now moving into production rather than remaining solely a design concept.
