SolidUltra has raised $3.4M to build a modular medium-voltage solid-state transformer that connects directly to the grid and delivers 800 VDC to AI data centers. The company's technology collapses the traditional transformer and rectifier chain into a single modular 100 kW cell, which it says enables deployment in days rather than months.
Watt & Well is the investor. SolidUltra is still in development and is selectively engaging with data center operators, hyperscalers, and strategic partners.
