Battery
Buy power when it's cheap, use it when it's expensive, automatically. Part of the energy subscription, together with a heat pump and solar panels.
It saves your electricity for the expensive hours
A home battery stores electricity until you need it. When the panels give more than you use, or when the price is low in the middle of the night, it fills up. Then you use that power in the expensive evening hours, instead of buying when everyone else does and the price is at its peak.
You skip buying power when it's priciest, without touching a setting
The control handles the timing around the clock. It charges when power is cheap and empties when it's expensive, and the saving turns up in the background. How much you save depends on your consumption and how much you produce yourself, and we work that out when we look at the whole.
A battery isn't a backup generator, and we won't pretend it is
It won't keep the house running through a long power cut, and it isn't meant to. A home battery moves your everyday power from the expensive hours to the cheap ones and shaves the peaks. Full stop. We size it for your everyday life, not for a disaster.
It all fits together
no battery without a heat pump and solar panels. the three make each other efficient.
We only sell them together, at a fixed price with nothing upfront, and make our money keeping the system tuned year after year.
