Just so you don't think I'm just trying to drive you insane Tim
I do understand how the theory works, the invertor matches the incoming supply, ups the voltage a bit which in theory feeds in to the total coming down the line and so the main source reduces it's flow automatically. I get the idea. The point my contact makes ( and I'm beginning to wish I hadn't asked him...) is that the quantities in domestic units are so tiny that the effort leaches it all off in heat.
Anyway, any input appreciated, I'd love to know the reality here.
