Tumble dryer on.
Croissants cooking in the oven.
Kettle boiling.
Battery charging.
At -2p/kWh it won't quite pay for an Xmas present - but certainly fun to see what sort of odd behaviours it drives.
Our 4.8kWh battery took advantage of the negative electricity pricing yesterday.
It charged when power cost ≤ £0.00 and discharged the rest of the time.
Basically filled and emptied twice.
@Edent does it export from the battery to the grid, or was it just discharged to supply your house?
@Noneeeed It can do. But in general it keeps balanced with our usage. That's because it is usually more cost effective to use rather than sell.
