Enphase Ramps Up Solid-State Transformer Production for AI Data Centers
Event summary
- Enphase Energy is now manufacturing power modules for its IQ Solid-State Transformer (IQ SST) in Texas, targeting AI data centers with 800 VDC power architectures.
- The power modules, each 4 kW, can be scaled to create multi-megawatt IQ SST racks with capacities up to 5 MW.
- Full-system validation is underway, with demonstrations expected in November 2026 and customer pilots planned for 2027.
- Enphase leverages its existing microinverter manufacturing infrastructure to scale production, aiming for tens of gigawatts annually.
The big picture
Enphase's move into AI data center power infrastructure aligns with the industry's shift toward 800 VDC architectures, reducing the need for local battery buffering. The company's ability to leverage its existing manufacturing capabilities for high-volume production positions it as a key player in the evolving power electronics market. The strategic focus on domestic production also underscores the importance of regulatory compliance and supply chain resilience.
