    Hello,

    I know the Huanyang is knot a big brand VFD and their are some reviews on youtube etc.

    However, I was wondering if anyone here has manage to put some significant hours on the Huanyang in their workshop. Is there any reason not to buy Huanyang in terms of reliability.

    Thanks in advance.

    I got one for my new grinder. I've ran the motor unloaded overnight, the drive was blowing cold air in the morning and the motor was still running. That's the extent of the use that I had of it. I will get back to you.

    I did record some the minor issues with it. Firstly the fan is on all the time whether the motor running or not. It reminds on that the main power is on, but annoying nonetheless. Another weird thing is there is only one grounding screw in the unit. This means the incoming and outgoing power plus instrument cable shields have only one terminal to connect to. That's at least three wires, four for me. But wait, there are two ground connection symbols stamped into the plastic housing right? Yes, but the other terminal marked as ground is actually the AC input (R). It would be a major NO NO to ground one of the lines. Well your breaker should trip. LOL My work-around for that was to bring the grounds to one stud and run a #14 green from there to the VFD ground terminal. That works.

    Also, my unit was programmed way different than the manual suggested were "Factory Settings." The manual said factory frequency reference is 50.00 Hz, mine was 0.00 Hz. I still haven't been able to get a factory reset to take. Not even sure that works as in one area of the manual it states that parameter is 'reserved.'

    My take on it was four years ago they were having some quality issues. Nowadays the quality has seemed to be improved and the product is priced very low. I got a 2.2 kW (3 horsepower) for CAD $200 delivered. Everything else decent (TECO, Yaskawa, Schneider Altivar) I looked at was at least $100 to $200 more, plus freight for a 1.5 kW (2 horsepower). So I took a chance to use and review the VFD.

    I believe that @parker has been running his for a while.

    Cheers,

    Dan

    I also have one and have about 8-10 hours running time on it, so far, so ok. The fan does stay on and is quite loud (not the end of the world) non the less annoying, the programing is like Dan said slightly off but just one changed allowed me to run, I had mine to the door for 180 CAD 1.5kW 2hp

    I ended up buying a Teco FM50. Been running steady for three years without an issue. It’s not sealed so i screwed a large plastic tool box to the wall and mounted it in there. Not the best option but it seems to keep it protected enough that it’s still alive. I think I paid $260 shipped for the VFD. One of the benefits was that it actually had a usable and deatailed manual with it.
