Out out voltage of 3 phase inverter

i presume the
22B-E012x104   7kW unit

or maybe the
22B-E9P9x104     5.5kW unit


Be aware that the output is not a sine wave, anything like, so the normal RMS voltage and current thing  will not read on most meters.

really the incoming 3 phase is rectified to give a DC bus, and then fast switching transistors connect and disconnect with varying mark to space ratio, to give an average force on the coils equivalent, roughly, to a sine wave. (long bursts on and short time off to mimic the peak of the sine, and long off, short on to mimic the near zero part.)

The chopping frequency is sometimes called carrier, after the radio analogy of modulation.
