For what my opinion is worth, you might try measuring the Eddy current loss first.
If you can cobble an E Core together without much work to try in the inverter then that would obviously answer the question. In either case you are trying to measure idle current (no load).
Every big E-Core I have tested has been horrendous, much the same as Godohs experience, or worse.
If you power one of the E cores, as it is, without any secondary load, you should find that after a while the Core becomes quite hot or very hot, that is also a basic indication of power loss (Heat) you will be dealing with at idle in an inverter.
