6 MW solid-state transformer
24 MW power block · SST + BESS
For AI factories, 6 MW SST units with integrated BESS feed standardized 24 MW power blocks at 34.5 kV. The simplified path to native 800V DC delivers $1.49/W installed cost and 95.7% end-to-end efficiency — versus $2.18/W and 90.7% on legacy architecture.

Megawatt MCS depots
For truck charging, 1.2 MW SST units connect at 12.5 kV at the depot — replacing step-down transformers, switchgear, and low-voltage rectifiers that conventional MCS installations require. The same core platform WattEV deploys across its charging network.
