After almost 3 years, I finally have grid power.
For some reason, it's weak voltage (~185v) but i'll take that over a noisy genset.
Because I can't feed in, i've connected the line to AC1. I've raised the limit to 20Apms, but it acts very weird - sometimes it goes up to 3kw drawn from the grid, sometimes it's ~1.5kw, but usually stays around 2-2.5kw.
I've tried with all 3 phases and it acts the same.
I understand that I am at the end of a very long line so the voltage is now great, but I don't see why the quattro can't pull more amps from the grid? Any what's really strange it's fluctuating...
