[RE-wrenches] VFD drives

[jay]

HI All,

I’m being asked to comment about running a 10hp 3 phase well centrifugal pump off of a 30kw single phase generator with a VFD drive.
This well pump is located in a tank for fire fighting applications, so its not down a deep well meaning almost no head pressure. And the start time can be quite slow as its not supplying a house/pressure tank.


I”m not an expert on VFD drives, but I figure many of you are.

My question, based on the question from the engineer is:

1. is there any issue with running a VFD off of a good quality 30kw brand new Kohler turbo propane generator?
The engineer seems to think there is but he won’t say why. 

i can’t think of any reason at all?

This generator is only running this one load, the well pump.
