10 kWh battery – for larger families or high consumers
- Ideal for: Families with 3+ people, electric boiler, or heat pump.
- Annual electricity consumption: 4,500 to 6,500 kWh.
- Solar panels: Installations from 6 to 8 kWp.
- Advantage: Increased self-consumption, higher savings on your energy bill.
14 kWh battery – for intensive use or energy independence
- Ideal for: Homes with an electric vehicle, heat pump, and/or home office.
- Annual electricity consumption: 6,500 kWh and more.

How do I make the right choice?
- Log in to Mijn Fluvius and compare your injection (what you put on the grid) with your take-off (what you take from the grid).
This shows you how much energy you are not consuming yourself and how much of a buffer a battery can provide for you.
- Consider your future plans (e.g., electric vehicle, heat pump)
- Decide whether you primarily want to save money or also want to invest in energy independence
