1.2 MW SST for megawatt charging
12.5 kV → 1000V DC · MCS depots
Heavy-duty charging
1.2 MW SST
Depot-scale SST for megawatt truck charging — replacing step-down transformers, switchgear, and low-voltage rectifiers. The same core platform WattEV deploys across its charging network.
At the depot, 1.2 MW solid-state transformer units connect at 12.5 kV and deliver 1000V DC for MCS charging — without the conventional stack of step-down transformers, switchgear, and low-voltage rectifiers.
It shares the WattAI SST platform with the 6 MW AI unit, right-sized for heavy-duty freight charging corridors.
