How does a home battery work?
A home battery stores electricity when there is surplus and returns it when you need it. This helps you use more of your own generated energy and manage electricity prices smarter.

How does a home battery work?
Use your own solar energy smarter
Solar panels generate electricity mainly during the day. But many households use more energy in the evening. A home battery stores part of your generated power so you can use it yourself later.
- Generate power during the day with solar panels
- Temporarily store surplus in the battery
- Use it yourself later in the day
- Less dependent on the grid

Charge when it is smart, use when you need it
During the day your solar panels charge your battery. In the evening your home uses the stored energy. At night you need less power from the grid.
- Generate — during the day with solar panels
- Store — surplus in the battery
- Self-use — in the evening
- Buy less — also at night

Smart with energy prices
Store power when it is advantageous
A home battery can help you manage energy prices and your own usage smarter. Especially with a dynamic energy contract, the timing of charging and discharging can make a big difference.
- Charge cheaply at quiet moments
- Avoid expensive moments with stored power
- Smart consumption with dynamic prices
- More control over your energy costs
