Modular MV Solid-State Transformer

Power the
800V era.

SolidUltra builds a modular medium-voltage solid-state transformer that connects directly to the grid and delivers 800 VDC to the AI data center — deployed in days, not months.

// What we build

One module. Medium voltage straight to 800 VDC.

Legacy sites stack a bulky transformer and a separate rectifier to reach DC. SolidUltra collapses that chain into a single modular 100 kW cell. Cells stack in series on the medium-voltage input and parallel on the DC output, scaling from one rack to tens of megawatts — built on automotive-grade SiC, not custom high-voltage silicon.

>98%
Grid-to-DC efficiency, vs. ~92% for a transformer + rectifier.
4×
More compact — rackable where a substation once stood.
Days
To deploy, not the 12+ months a substation takes.
N+k
Redundant, field-replaceable cells — graceful degradation, no single point of failure.
