VFD Single-Phase to 3-Phase Converter, Used on ≤3HP(2.2kW) 10Amps 200-230V 3-Phase Motor, Input/Output 200V-230V,Variable Frequency Drive

I received a defective 7.5KW VFD. I contacted Amazon for warranty support, and Amazon directed me to Huanyang. I contacted Huanyang, and after a brief exchange of steps to debug and the results, Huanyang agreed to send me a replacement unit. The replacement arrived within a couple of days of our exchange. The replacement works perfectly. Time will tell if it holds up, but I am very pleased with the support I received. There are mixed reviews of this unit, but most problems seem to be evident right out of the box or upon initial powerup. That was true in my case - unit reset itself randomly right out of the box. This replacement is working as expected, so I am hoping it stays that way. There are more expensive options, and there are also cheaper options, but I really like the features and function of this box so, fingers crossed.

Why did you pick this product vs others?: I have been using this VFD on my 7.5hp 16" Delta radial arm saw for about 2 years now. It has been working perfectly. I also have some name brand VFD's to run my 3 phase machines on Single phase. These inexpensive VFD's are a lot easier to setup. They have a fraction of the possible setup parameters of my Hitachi VFD's but I don't have any need for the fancy parameters and they really just get in the way making initial configuration more difficult. If your income depends on the proper functioning of your machinery I can see why you would want to use a name brand VFD with good support and a good warranty. But if you are a hobby guy like me these VFD's are a great value!

I bought this to run a 2HP motor on a Bridgeport copy that is 3 phase. Like others say, the manual has some errors. It shows on the wiring page to hook up the single phase power to R and T. It didn't work that way. Hook it up to R and S. The best advice I can give is that before you order it spend some time on YouTube to see where others have struggled or succeeded . Do a search for "Huanyang GT" There you will find several videos including "VFD GT series operation" I took my laptop to the shop and followed it step by step. It ran perfectly with no issues at all and I have never wired a VFD. Watching videos will get you familiar with the functions. Great bargain for the money if you have some electrical skills! You will need to wire in a disconnect and likely low voltage control wiring. I went through the extra effort to install it in a enclosure. EDIT: After a successful install, I bought another larger unit for my 5hp Lathe. More challenging to install but well worth the effort. The amount of electrical hardware you get to remove is staggering! My personal opinion is to stay away from "Autotune" and just enter your basic motor parameters and HZ. Start slowly. As you learn the programming language things will start to click and make sense. Managed to get everything programmed exactly how I wanted it including the mechanical brake. Great product for the money. Patience.....required for this project but I couldn't be happier with the results!

I'm currently dealing with the breaking resistor ...scam? I don't know what the deal is but after many emails back and forth I was told the top of their line 7.5kw model is the only one that comes ready to accept a resistor and so I shelled out the extra cash for it, many emails later i was told a 1000W 75ohm resistor was acceptable for this unit.. with everything wired as per their videos I hit start and let the bandsaw get up to speed, as soon as I hit the stop button it VIOLENTLY EXPLODED with my hand on the unit! sparks blew 3 feet out of the side vents in both directions. First I was told the problem was that my motor had to be three phase so I sent a photo confirming it is indeed a three phase motor. next my wiring was wrong so I sent photos of my wiring only to be told it was wrong with advice to connect it exactly as I had it. Finally, after sending a home video showing all my connections and terminations I'm told I connected my resistor wrong.. get this.. "I should connect to the brackets that hold the resistor in place instead of the coil terminals" What!? that sounds like an expensive jumper and not a resistor. the unit was actually running my bandsaw but if breaking is not a viable function why sell it as having it and then run me in circles when it blows up!? I'm told they're sending another unit, if they do I guess I won't try to use a breaking resistor as I can't get useful or accurate information from the source. I've seen videos of these units with a resistor working, was I given bogus information on the resistor value, can anyone confirm? I have a 220 3hp 2.2kw 60hz 9.1A motor in delta configuration running a 24" bandsaw.

I used this to power an old 10Hp metal turning lathe. We don't have 3 phase power in our garage and I didn't want to get a phase converter. This VFD was easy to set up, cheaper to buy than a phase converter, and made the machine safer to operate. I am only running the lathe at 60Hz for now, but tested the variable speed and it works great. Nice and smooth. I may be back for another VFD once I get my hands on a milling machine.

I ordered two inverters one for a 2hp, and one for a 3hp motor, and they work awesome. I found them very easy to program and wire. I Will definitely order another one if needed. Great customer service. 👍

Worked well when installed on a 7.5 Hp motor 3 phase motor. Ran on 230 volt single going in to supply 3 phase out at 60 Hz, no variable speed used. Unfortunately it only lasted 1 year with the panel dead, no output. Motor only pulled 15 amps under load and bought this oversized due to running on single phase. Will be replacing with something different.

Considering the price, this is a pretty good deal. As with most foreign made products, the instruction manual is not as clear as it could be, but overall not too bad. There was enough information available online to help in setting up the VFD. The main thing missing was the wiring for the single phase connection, the manual shows a 3 phase connection, which doesn't help for a single phase 220 volt connection. If anyone else runs into the same issue, the 220 connects to terminals R and T. I can't comment on long term performance, but the available features on this unit are comparable with high end VFD's. UPDATE - have had this installed now for over 3 years without any issues, very satisfied with the performance.

I am impressed with how well this works but am curious to see how long it will last. So far so good though
