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).   Yes definitely needs testing to find out what the Idle is.   Quote   Every big E-Core I have tested has been horrendous, much the same as Godohs experience, or worse. The EI transformer inverter I did, was about 20w running as an Inverter, I don't call that Horrendous, I cant find the 230vac idle test but I think it was around 7w give or take abit. As with some ready wound toroids, The same rule also applies to EI transformers, they need more turns added on to get the idle down to a somewhat manageable level (not easy to do if its already assembled and no real estate left) and also needs a good choke, still not near as efficient as a toroid.
