<div dir="auto"><div>There should be no issues. My rule of thumb is very hard starting 15 horsepower three phase motor will start and run with a quality 30 kilowatt three-phase generator. That's across the line starting with massive current. You can program your VFD such that there is no massive surge and so a 10 horsepower on a 30 kilowatt will be absolutely no problem.</div><div><br></div><div data-smartmail="gmail_signature">-James Jefferson Jarvis<br>APRS World, LLC<br>+1-507-454-2727<br><br>(Sent from my phone.

<br>
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.<br>
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.<br>
<br>
<br>
I”m not an expert on VFD drives, but I figure many of you are.<br>
<br>
My question, based on the question from the engineer is:<br>
<br>
1. is there any issue with running a VFD off of a good quality 30kw brand new Kohler turbo propane generator?<br>
The engineer seems to think there is but he won’t say why. <br>
<br>
i can’t think of any reason at all?<br>
<br>
This generator is only running this one load, the well pump.<br>
