So sadly, here in Australia the Multiplus II is certified for Standalone operation (ie. grid-connected, but no feed-in permitted). However, the local energy network will not permit grid connection at all, for the somewhat decent reason that I could flick a switch and the Multiplus would do feed-in...
Anyway, since I bought it before finding out, I'm stuck with having it behind an ATS, effectively as a generator for my house. I'm expecting that I'll need some re-wiring or some Node-red trickery in Venus to handle when the draw is greater than 5kW
How do I set it up in that mode? Does everything have to be on the Critical AC output? or does it not matter?
