400V DC to 230V AC Inverter(Electric van)

My electric powered e-Jumper van has a 400V DC connection point/outlet designed for chassis builders. Is there any device in the Victron selection that could convert the 400V DC voltage to 230V AC? Or could I use a Multi RS with its 450V DC solar panel input as the connection point?

Nothing in the Victron range is targeted at this voltage.
It would not be a good idea to connect a PV type MPPT to this source, due to the available current.
Yuo should be able to find other DC /DC or DC/ AC converters on line.

Thank you for the response. So just because the battery is essenitally “infinte” power source it will confuse the MPPT? Not like the sun, which is changing constantly and the MPPT has to find a maximum point.

The MPPT tries to do a power sweep about every 10 min to find the max power point.
The problem with the battery as a source is that the power keeps increasing as the input current is increased by the MPPT sweep. If this is not limited, it will exceed the maximum capability of the MPPT. This may end up destroying the MPPT.

MPPTs are not to be connected to batteries in place of the PV input. It is, by definition, not a suitable device for this use-case.
