Hi,
I am wondering if a software programmable split phase
true sine inverter outputting 230VAC/60Hz split phase
designed for North American power could be used in
Europe to power 220VAC/50Hz single phase assuming it
could switch to 220VAC/50Hz split phase. I guess both
wires would be live at 110VAC instead of there being a
common, is this safe/legal? :)
It's not legal AFAIR. There is no 50:50 split-phase in Europe anymore, maybe with the exception of tiny legacy grids way out in the boonies. At least for new installation you can't do that. Just like here in the US electricians refer to line (often called phase over there) and neutral. And they expect neutral to be neutral ;-)
You should be aware of another snare, "classical earth ground" or whatever they call that. Used to be popular in Germany and it's dangerous: Protective earth is hardwired to neutral in the wall outlets. Now imagine someone touching "neutral" on your unit ... bzzzz ... THUD.
I was thinking about it more and since the output of the converter is
isolated, I think one of the 110VAC phases can just hook right up to
ground, and then the other will be the live 220VAC/50Hz.
cheers,
Jamie
