<div dir="auto">I’ve years of experience running vfds on generator power. No issues. Personally, I run numerous old cast iron woodworking machines that all have 5 and 10hp 3p motors with VFDs from a 15kw Kubota open frame generator. 15 second ramp up time. And my generator is single phase.</div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Jul 11, 2024 at 10:06 AM jay via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)">HI All,<br>
<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>
