No-one heard of this or have an opinion?

Never heard of it but it seems based on VESC: https://vesc-project.com/
Thats a quite popular project for ebikes. Apparently they scaled it up.

Arlin Sansome aka Arlo (endless sphere crx leaf inverter maker) is part of the team developing this.

I did know some of the EV veterans had developed this as a commercial thing. Reading through the PDF doesn't mean a lot to me though.

Does it sound good?

They are developing version that supports BLDC for now. There is support for commutation input.
ABZ and resolver interface is in development as well as IPM and ACIM motor support. They still dont have weakening.
It seems good all around inverter design. Software is widely used and adaptable etc...

I am not convinced though. I wont build any new power sections anymore. There is plenty of them in scrapyards. What we need are replacement brain modules the way of JackBauerss Prius/Lexus and JoHus Leaf inverter brain. And mine and TomDB Ampera/Volt contribution.

Thanks. That helps me understand

I am being too critical maybe. So I offer the benefit of doubt If I could buy their control board and interface various automotive inverters with it.
Hm, wait I think there is a VESC brain design that supports isolated power stage. We could also try that...
