Home battery 10 kWh: who is this the right size for?
10 kWh is the 'standard size' for many households: large enough to cover a substantial share of your evening usage with your own solar energy, without paying for capacity you never use. Below you can see whether 10 kWh fits your situation.
Free and no obligation · Sizing advice based on your situation
- Standard size for families
- Often suits 3,500–4,500 kWh usage and 10–14 panels.
- More evening on your own power
- Capture a large share of your evening usage with solar power.
- Worked example included
- See what 10 kWh does for a typical family with 12 panels.
Who is 10 kWh right for?
10 kWh is usually right for a family in a terraced or semi-detached home with average to slightly above-average electricity usage and a normal solar panel system.
- Family (2–4 people) in a terraced/semi-detached home or pair of semis
- Annual usage around 3,500–4,500 kWh
- Roughly 10 to 14 solar panels
- No heat pump or electric vehicle yet, or only limited use of either
- Goal: use as much of your own generated power as possible in the evening
Worked example: family with 12 panels
An indicative example for a household with around 4,000 kWh usage per year and 12 solar panels. The figures are a guide, not a guarantee — your situation determines the outcome.
- Annual usage
- ± 4,000 kWh
- Solar panels
- 12 (± 4,800 kWh generation)
- Usable capacity per day
- ± 9 kWh
- Typical evening/night usage
- ± 6–9 kWh
- Self-generated power used
- a large share of the day's yield
With 10 kWh you capture most of your evening usage with your own solar power on an average day. On peak days (lots of sun, little usage) some power may still go back to the grid.
Is 10 kWh too small, right or too large?
Too small if…
Do you consistently use more than ~4,500 kWh, or are you adding a heat pump or electric vehicle? Then 10 kWh will run out too soon on many evenings and 15 or 20 kWh is a better fit.
Right if…
With average family usage and a normal solar panel system, 10 kWh is often the price/capacity balance: enough buffer for the evening, little unused capacity.
Too large if…
Do you have little evening usage or a small system (up to ~8 panels)? Then part of 10 kWh often stays unused and a smaller size is more logical.
What does a 10 kWh setup look like?
10 kWh is usually built with two to four modules or one larger unit. In many homes a single-phase connection is enough, but with more heavy loads or an existing three-phase consumer unit, a three-phase system may make more sense. The charge/discharge power is ample for normal evening usage. When choosing, consider space in your consumer unit or utility room and the option to expand later, so you are not stuck if your usage increases.
Example batteries around 10 kWh
Huawei LUNA2000
Stapelbaar in stappen van ongeveer 5 kWh; veel toegepast bij zonnepaneelsystemen.

Expand later?
Many modern home batteries are modular: you can add extra modules later. If you are torn between 10 kWh and a larger size because a heat pump or EV may be added, choose a system you can expand.

Frequently asked questions about 10 kWh
Is 10 kWh enough for an average family?
For a family with annual usage around 3,500–4,500 kWh and no major extra loads (such as a heat pump or electric vehicle), 10 kWh is usually a good size to cover a large share of evening usage.
What is the difference between 10 kWh and 20 kWh?
20 kWh stores roughly twice as much and is intended for households with high usage, a heat pump or an electric vehicle. For an average family without those heavy loads, part of 20 kWh often stays unused; then 10 kWh is more efficient.
Do I need solar panels with a 10 kWh home battery?
A home battery is most useful combined with solar panels, because you then store power generated during the day for the evening. Without panels, a battery can sometimes still be interesting with a dynamic energy contract, but the size choice changes.
