I have AC motor const speed 50 KW, 3 ph 380V, 50 HZ.
While the available I/P power source is 480 V AC, 60 HZ.
Could this inverter supply this motor.
Also, need to confirm the O/P will be Y in order to use one phase and neutral as 220 V supply for lighting load?
Need to confirm the above loads plus if we have zone 2 version of this converter.

Please advise.
