Charge batteries and prepare to stabilise the grid.
The overall energy usage looks like this.
Key thing here is that the red (imported electricity) is huge in the early morning.
The house is then powered by the battery.
(red flat lines at 0/ turquoise, which is the battery goes above 0).
The battery drains but then the yellow, which is the solar system kicks in, the battery is then trickle charged - its turquoise line goes below 0.
This means we used all of the solar generation, coupled with the early morning charging to avoid the 82p peak.
