What does that mean? Are you saying that you have a quantity of 42 solar panels, each capable of 330V output at 33VDC?
For a 380V motor powered from a VFD, your DC bus voltage must be a minimum of 536VDC. So if you have modules capable of only 33VDC, that means you must put at least 17 modules in series to get to 536VDC. That will then give you only 330W at 380V for the motor. To get 9.3kW capacity, you would then need 29 sets of these in parallel. 29 x 17 = 493 of those solar modules to run that motor...
Such is the problem with solar power.
