Don't even consider the YL VFD Drives HY is a much better VFD Drive if you have a genuine one
I don't know what Rattmotor has to do with HY is just a name that I would not trust.
The 3Kw HY has the same Heat sink as you are showing, the 2.2Kw does not show the Heat sink which you are most likely comparing it to.
Just look for the Genuine HY 3Kw
