There are Jim, but just as you said, these commercial systems are so new and too expensive for this purpose.
An example of these is this VELOX DC-DC charger unit that its designed to operate on ≈800-900V DC buses, which are a growing trend (DC buses) in medium and large commercial applications nowadays, where it is cheaper and more practical to have HV-DC bus connecting dispensers like this one, attached HV solar PV, also energy storage systems, etc. everything on DC with the option to tap into the utility via a bi-directional AC-DC units as a backup. (know as DC grids or DC micro grids) https://www.turbopowersystems.com/solutions/transport/ev-charging/velox-stand-alone/ This device in particular, can take ≈800V DC input from any DC source and deliver a fast charge to EVs from 150-920V DC at 150kW max power with ≈98% efficiency. Marco PS. I think this is how Tesla and WattEV are able to make these massive charging sites (80, 100+ stalls) combined with Solar PV, ESS and DCFC without depending on the grid for peak power and these things.
