You have single phase line and 3 phase fan, right? If you do, you need to double rate the drive. With a 5 to 10 second accelerate time, there is hardly any inrush current. That is what the power company wants.

Smart guys tell me a motor on VFD takes less current. Past what I know.

The harder question is what is the quality of drives. Is the expensive one that much better than the cheap one?
