Enphase builds 4 kW modules for AI racks

Enphase is building 4 kW power modules in Texas for solid-state-transformer racks aimed at 800 VDC AI data centers, with hundreds of modules scaling racks to 5 MW, according to Enphase’s announcement. Full-system demonstrations are expected in November 2026 and customer pilots in 2027; operators should treat this as power-architecture validation—not shipped capacity—and compare it with the grid-access bottleneck before designing around 800 VDC.
