It has performed flawlessly right from the start, at this time 15 months later. Five stars for that one. After that initial positive experience, I bought the 7.5kW to supply an even older lathe. My mistake was ordering it months in advance of when I knew I'd have the time to install it, so now desertcart support has long expired. This second one does not power up, at all. Error codes? It does not even turn on, no lights, no output, nothing. Is it possible I installed it incorrectly? Maybe, but I installed the first one perfectly, and the second one the same way. Tested on different circuit, still nothing. Zero stars for this one, so we're averaging 2.5 stars now. The company claims great support for a year after the sale, and I've read of some positive experiences. It's been a couple days now with no response whatsoever, so now I'm dropping it to an even Two stars, and ordering a new alternative from a competitor. Since the installation is all ready to go now, I'll know if the next one functions immediately upon delivery, solidly inside desertcart's support window. UPDATE: It took several days to get a service response, but after only a couple exchanges, they volunteered to replace the faulty unit. The replacement works perfectly. Review: 2 year old, no problems. - 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! ## Features - The VFD can run 3-phase motor with 200-230V AC single-phase or three phase input - Supports mcah3 function and RS-485 communication//Supports remote potentiometer speed control and remote switch start/stop - Support fast brake resistance installation - Easy to connect the motor/easy to use - The VFD has the advantages of low noise and low electromagnetic interference - Low failure rate/Designed to be non-flammable - Achieved CE listed - Support DPS vector control - 1 Year replace .If there is an error code in the vfd and you do not know how to operate, pls contact me or the after-sales service ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B077KSN4C5 | | Antenna Location | Backup power, Household appliances, Job site, Workshop | | Best Sellers Rank | #43,685 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #16 in Motor Speed Controllers #50 in Electrical Motor Controls | | Brand | HY HUANYANG | | Built-In Media | TOOL | | Color | 220VAC 1/3phase input-10HP | | Customer Reviews | 4.1 out of 5 stars 118 Reviews | | Display Type | Graphical LCD | | EU Spare Part Availability Duration | 1 Years | | Electrical Output Waveform | Modified Sine Wave | | Energy Specifications Met | (unset) | | Frequency | 0.5 Hz | | Input Voltage | 220 Volts | | Inverter Capacity Volt-Amp | 7500 | | Item Dimensions L x W x H | 8.7"L x 6.7"W x 5.9"H | | Item Weight | 6.61 Pounds | | Manufacturer | Huanyang Electrical | | Mfr Part Number | GT-7R5G-2 | | Model Name | GT-7R5G-2 | | Model Number | GT-7R5G-2 | | Output Power | 7500 Watts | | Output Voltage | 220 Volts | | Peak Output Power Watts | 10000 | | Power Source | ac | | Recommended Uses For Product | Backup power, Household appliances, Job site, Workshop | | Standby Power Shutoff | High Efficiency | | UPC | 724509858367 | | Unit Count | 1.0 Count | | Voltage | 220 Volts | | Warranty Description | 【Warranty】: 1 Year replace .If there is an error code in the product and you do not know how to operate, please contact the seller | | Wattage | 7.5 KW | ## Product Details - **Brand:** HY HUANYANG - **Model Name:** GT-7R5G-2 - **Power Source:** ac - **Recommended Uses For Product:** Backup power, Household appliances, Job site, Workshop - **Wattage:** 7.5 KW ## Images ![10HP 7.5KW VFD Single-Phase to 3-Phase Converter, Used on≤7.5HP(5.5kW) 34 Amps 200-230V 3-Phase Motor, Input/Output 200V-230V,Variable Frequency Drive - Image 1](https://m.media-amazon.com/images/I/61I+0VtVtvL.jpg) ![10HP 7.5KW VFD Single-Phase to 3-Phase Converter, Used on≤7.5HP(5.5kW) 34 Amps 200-230V 3-Phase Motor, Input/Output 200V-230V,Variable Frequency Drive - Image 2](https://m.media-amazon.com/images/I/81iARGckmfL.jpg) ![10HP 7.5KW VFD Single-Phase to 3-Phase Converter, Used on≤7.5HP(5.5kW) 34 Amps 200-230V 3-Phase Motor, Input/Output 200V-230V,Variable Frequency Drive - Image 3](https://m.media-amazon.com/images/I/91y+6tnTfjL.jpg) ![10HP 7.5KW VFD Single-Phase to 3-Phase Converter, Used on≤7.5HP(5.5kW) 34 Amps 200-230V 3-Phase Motor, Input/Output 200V-230V,Variable Frequency Drive - Image 4](https://m.media-amazon.com/images/I/71Jb+zLav2L.jpg) ![10HP 7.5KW VFD Single-Phase to 3-Phase Converter, Used on≤7.5HP(5.5kW) 34 Amps 200-230V 3-Phase Motor, Input/Output 200V-230V,Variable Frequency Drive - Image 5](https://m.media-amazon.com/images/I/61ocd7X2JFL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Will this work on my 10hp air compressor setup going from single phase to 3 phase setup? Or is there a larger one that works better for this applicati** A: It should work, this converter runs at 50 hertz, it ramps up from 0 to 50 hertz slowly. I am using on a 30” band saw that is very hard starting and it works flawless. You will have to Remove the factory switch on your compressor and wire vfd in its place, I am not sure of the wires for the pressure switch. But yes this vfd will convert single to 3 phase. **Q: Does this unit have auto-start when input is energized?** A: It can if you set that option. Defaults to no. **Q: I continue to get tE error no matter what i do. Heard a pop inside the unit im guessing a cap blew. Anyone have similar problems?** A: I can't answer your question specifically, but I have had 4 of these units fail. IMHO, these units are sub standard. None of the ones which failed were being "pushed", all of them were rated at least 50% above the load they were controlling. I suspect you are looking at a failure oh one of the triacs, not a cap. Since switching to another brand of VFD, I have had no failures and better performance. **Q: Will this power a 1950s 10hp 3 phase american tool works pacemaker lathe on single phase or 220? i do not have 3 phase service.** A: yes that is what this is desigfned to do ## Customer Reviews ### ⭐⭐⭐⭐⭐ Issues on second purchase, but all has been resolved quite professionally. *by B***. on March 5, 2026* First I bought the 4.0kW to supply an old Bridgeport.

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. ## Frequently Bought Together - 10HP 7.5KW VFD Single-Phase to 3-Phase Converter, Used on≤7.5HP(5.5kW) 34 Amps 200-230V 3-Phase Motor, Input/Output 200V-230V,Variable Frequency Drive - Braking Resistor 1000w 100 Ohm Accessory for VFD 7.5kw Inverter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/57920422-10hp-7-5kw-vfd-single-phase-to-3-phase-converter](https://www.desertcart.hr/products/57920422-10hp-7-5kw-vfd-single-phase-to-3-phase-converter) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-22*
