HY HUANYANG VFD,Variable Frequency Drive,AC 1 or 3 Phase 220V Input, 3 Three-Output,for 220V Motor/Spindle Speed Rotation,HY Series(4kW 5HP)

good

Downgraded to the HY series because I couldn’t get GT series inverter to work correctly. I really wanted the GT series, but after struggling to get it working correctly I gave up and bought the HY series instead.Tech support was useless. Between the time difference (US vs China) and the lack of a flowing conversation (wait 12 hours for each response and hope they understand what you’ve asked), you’re pretty much on your own with these. The broken English manuals are horrible, but they’re not always easy to interpret. If I had endless time to mess with it, the GT would probably work, but after 2-3 weeks I’ve had enough. Time to move on.

First time setup this make of VFD, it is easy to to set up and work great. Will use this make next time.

I am not good in reading the manual on electrical diagrams. . I just want to know how to program to run the 5 h.p. motor on the machine. How to change the speed, forwarding and reversing. Nothing shows in the manual.I managed to hook up the inverter.Nothing shows in the manual.

Purchased this product Sept. 23, 2019. Installed it on 3 phase 5hp air compressor in my garage that uses typical residential single phase! It is priced affordable if and far is a cheaper option that have 3 phase ran to your house. I am a industrial maintenance technician so setup was easy for me but would not be hard for someone that read understands ins and out of electrical troubleshooting and VFDs. I run the compressor daily and this VFD shows no signs of giving up and has done no harm to compressor electrical components. Will update review if run into future problems or issues.
