Enphase Energy develops and partners to deploy distributed solid-state transformers for data center power infrastructure

Type: Partnership · Technology: Data Center · Country: United States · Announced: 2026-07-07

Enphase Energy, a California-based power electronics manufacturer, announced the development of its IQ Solid State Transformer (IQ SST) platform, a distributed solid-state transformer technology designed for next-generation data center power infrastructure. The IQ SST converts medium-voltage AC power at 15 kV and 35 kV interconnection classes directly to regulated 800 V DC in a single stage, achieving up to 98.5% efficiency using 342 small power modules per 1.25 MW rack. Enphase joined the Open Compute Project (OCP) Foundation as a platinum member in late June 2026 to collaborate on next-generation computing hardware standards, sharing its IQ SST platform with OCP’s network of nearly 700 organizations. The technology eliminates the need for rack-level battery sidecars and uninterruptible power supply (UPS) systems, reducing space requirements and capital costs for data center operators. Enphase plans to begin full system demonstrations later in 2026, with customer pilots scheduled for 2027 and volume shipments expected in late 2027 or early 2028. The company projects U.S. demand for this architecture to exceed 11 GW by 2031, with potential applications extending to utility-scale solar, batteries, and high-power EV charging.
