As you use it nowAll of it moved

Use moved out of the expensive hours, like washing, the dishwasher and car charging, is charged at the lower rate. It also leaves the battery more power to sell when power is worth the most, so your share of what it sells grows.

Your share of what the battery sells

Once your home is covered, the battery sells power back to the grid. Your share comes straight off your bill as its own line.
