I have to admit I took the easy way out and coughed up for a Yaskawa GA5 (latest generation) last time round. These are £390 plus £80 for the dedicated EMC filter ie basically £470 all in. https://inverterdrive.com/group/AC-I...GA50CB018ABAA/. That might seem a bit extravagant but at least with these you know they will work and should be reliable. They are proper industrial parts with 150% overload (60 seconds) and will run at full power all day long (as if!!). The setup software is pretty slick too of course.

Most mfrs offer up to around 4kW maximum in 230V single phase, so above that the choice is rather limited. What power are you looking for here?
