    I must be missing something. I found a couple name brand 1-3Ph 3HP VFDs on the Drives Warehouse site for a around 3 bills when I looked before posting. $283-321.

    The Lapond VFDs come a company called Soyan. They have a pretty decent website. Seem separate from Huan

    Did you read through the feedback list?
    Mainly positive, even one that gave thumbs up for tech support!
    Usually with the Huan etc, tech support is conspicuous by its absence!
    Even the manual, although apparently long, was reportedly helpful!

    Well, I have at least one endorsement and a couple of "whatta ya got to lose"! I really do have little to lose by giving the cheapie a shot, and if it turns out to be a dud, then it'll be a 200 dollar lesson learned. I have learned one or two expensive lessons of my 60 some years.

    Thanks all.

    Amazon advertises free returns, so why not just get it and give it a good workout. You could get three of those for about the same cost of the one from Drives Warehouse. I'd say "go for it"!

    [edit] Automation Direct has a 1 phase input 3 HP VFD for $225:

    garagemark , I recommend looking at Automation Direct also. I have used their products for over 20 years an like them and their support. The link below is to a 10 Hp 240 volt drive that would work for your 5 Hp motor with a single phase input source.

    https://www.automationdirect.com/adc...pose/gs23-2010

    Look over the specs, I did not, and they will give you the rating when using single phase. Most drives not specifically built for single phase input will work just fine if derated to half of the rated Hp. I have seen some that only derate 1/3....
    The one I linked to would save you some money and I think they have free shipping on orders this pricey....

    Good Luck!!

    I've purchased 4 of these now of various ratings and they work great. If you email them they will send you the manual before purchase, and the manual is very good as well. I tend to buy one size larger than I need. I've got the 7.5HP version running my 5hp lathe. My only complaint is the input wire terminal size is a little small. Definitely recommend for hobby use.

    "Just spend a third more and get a known drive from Drives Warehouse. If you have issues they will likely even help you set the parameters correctly. One of their guys called me from home on the weekend to help me. Its worth it for the support."

    OK, fair enough; I'm all for smooth sailing. So I went to the Drive Warehouse site, and the closest thing I could find is worth 560 smackers.

    ODE-3-320153-1042, 230V 1 Phase input, 230V 3 Phase output (driveswarehouse.com)

    I'm sure it is probably a couple steps up from what I'm looking at, but it's a tad rich for my wallet. I don't make my living with these machines; I'm just a weekend warrior. I'm not opposed to upping the ante a little bit for something that might give me less trouble, but for a bit less than 200 bucks I have almost three tries to get a cheap smoker to work (I wouldn't do it- one and done if it's junk).

    I dunno, I suppose in this price point range, it's all just a crap shoot anyway. But if there IS a "to good to be true... but it is" drive out there that won't break the bank, I'm all ears.

    This message would make me RUN !! It is from the product information page. I agree with Bob go just a bit more in $$ and get a better supported and reviewed drive.

    IMPORTANT NOTE: Sometime it will smoke for the first time use due to the impulse current is large when power on, but it does not affect VFD performance,please rest assured to use and it will become normal for next time use.

    This is one of the few single phase input drives I have seen at 4KW/5hp rating. Almost all manufacturers stopped at 3 hp for a long time, unless you double sized a 3 phase only drive.

    P.S.
    I have heard stories that Huan Yang drives pretty much just work if used within spec, but there are some Huan Yang knockoffs on Fleabay. (Those everything and a bag of chips for cheap packages you see.) I don't know. I have a couple Huan Yang drives and they just work. I do have the benefit of having floundered my way through the setup of a half dozen different drives.

    Some evidence exists suggesting that "LaPond" is another name for Huanyang, a brand which has varied from acceptable to non-functional.

    As with anything, (and especially tech stuff) if it looks too good to be true, it very well may NOT be true... or at least may not be quite what you think it is.
