Thank you for your responses, very much appreciated and sorry if I'm misunderstanding how this all works; but the screen shots above were outside of a cheap IOG period and were when I would be paying full price for units. I thought, and maybe, as I say, I've misunderstood, but at that point, when it is full price electricity I would have thought that the WW integration doesn't do anything and the system is left alone, so if there is power in the battery it powers the house.
