What does a home battery cost?
A home battery costs on average between €6,000 and €8,000 for the product itself. The costs are mainly determined by the capacity in kilowatt-hours (kWh) and the chosen brand. Installation costs are added to this price indication, which depend on the complexity of the connection to your existing solar panel system and fuse box.
Overview of home battery prices
| Description | Price indication |
|---|---|
| Home battery (product) | €6,000 - €8,000 |
The prices in this table refer to the product itself. A home battery with a capacity of 5 to 10 kWh usually falls within this range, which is sufficient for an average household with solar panels. Brands such as Tesla Powerwall, LG Chem, and Huawei offer systems in various price categories.
Please note: the net metering scheme is being phased out until 2031, making a home battery increasingly interesting. Instead of feeding your excess solar energy back into the grid at a low rate, you store it and use it in the evening or at night. This makes investing in a home battery with solar panels attractive for the longer term.
The costs for a home battery exclude installation labour. The professional performing the job usually charges between €500 and €1,500 for the installation, depending on the situation in your home. All stated prices include VAT.
Price-determining factors for a home battery
The costs for a home battery are influenced by several factors. Below you can read what determines the price and why one installation is more expensive than another.
Capacity (kWh)
The storage capacity determines how much energy you can keep. A family with average consumption usually needs a battery of 5 to 10 kWh. The higher the capacity, the more energy you can store. This means more battery cells and a larger system, resulting in higher costs. A 10 kWh home battery is therefore more expensive than a 5 kWh model.
Peak power (kW)
In addition to capacity, peak power is important. This determines how many appliances can draw power from the battery at the same time. If you have a heat pump or charging station, you need more peak power. Higher peak power requires stronger electronics, which increases the price.
Battery type
Lithium-ion batteries are the most common due to their high energy efficiency and long lifespan. Lithium iron phosphate (LFP) is safer and lasts longer but is more expensive to purchase. The type of battery cell therefore directly affects the price you pay.
AC-coupled vs DC-coupled
An AC-coupled system has its own inverter and is more flexible for existing installations. You can easily add it to your current solar panel system. DC-coupled is more efficient because the current is not converted twice, but this solution is often more complex and requires more knowledge during installation.
Lifespan and charge cycles
Home batteries last on average 10 to 15 years or 5,000 to 10,000 charge cycles. A battery with a longer lifespan costs more but saves you replacement costs in the long run. Always check the manufacturer's warranty conditions.
Installation complexity
Installation is easier in new builds than in existing buildings. The professional then has more space and fewer obstacles. The distance between the fuse box and the installation location affects the required cabling. The further the battery is from the fuse box, the more material and labour is required.
Existing infrastructure
Is your fuse box up-to-date? Do you already have a suitable hybrid inverter? If not, additional costs will apply. An outdated fuse box may need to be replaced or expanded before the home battery can be connected.
Urgent vs planned
Urgent jobs are more expensive than planned work because the connected professionals have to adjust their schedules. If you plan the installation well in advance, you pay less.
Weekend
Work at the weekend costs more than during the week. Most professionals charge a surcharge for work on Saturdays or Sundays.
Region
In large cities, prices are often higher than in rural areas. This is due to higher parking costs, longer travel times, and generally higher business costs in urban environments.
Do not delay jobs
Schedule the installation in a timely manner. By waiting, you miss out on potential savings on your energy bill. A home battery is an investment that only pays off once the system is in use.
Choose a local professional
Local professionals can be on-site faster and are familiar with the local situation. This saves travel costs and shortens the waiting time.
Good preparation
Ensure that the installation location is clear and accessible. Tidy up the garage, cellar, or technical room beforehand. This saves time and prevents extra costs.

Additional costs and surcharges
Additional costs depend on the situation. At Zoofy, you do not pay call-out charges.
- Urgency surcharge: A surcharge often applies to urgent jobs because the professional has to adjust their schedule.
- Weekend surcharge: Work at the weekend is more expensive than during the week.
- Reinforcing the fuse box: If your fuse box is not suitable for the extra load, it must be adapted.
- Extra cabling: If there is a large distance between the fuse box and the battery location, extra cables and material are required.
- Upgrading the inverter: If you do not have a hybrid inverter, your existing inverter may need to be replaced or expanded.
- Structural adjustments: A home battery can weigh more than 100 kg, sometimes requiring reinforcements for wall mounting.
- Adjusting the group box: It may be necessary to install an extra group in the fuse box for the battery.
These additional costs are always discussed in advance by the professional performing the job.
How does the professional work when installing a home battery?
The installation of a home battery follows a fixed sequence of steps.
- Preparation and location determination: The professional determines the best place for the home battery. This is preferably a cool, dry room such as a garage, cellar, or technical room with temperatures between 5 and 25 degrees and sufficient ventilation.
- Electrical installation check: The fuse box and existing wiring are checked for suitability. If necessary, the fuse box is expanded or adapted to handle the extra load of the home battery.
- Mounting the battery unit: The home battery is placed in the designated location. For wall mounting, the installer takes into account the weight of more than 100 kilograms. The inverter is connected to the fuse box.
- Electrical connections: The wiring of the home battery, inverter, and fuse box is connected. The changeover relay ensures automatic takeover in the event of a power failure, so you still have access to your stored energy.
- Configuration and testing: The battery is set up via the accompanying app. Charging and discharging times are programmed based on your consumption pattern. The automatic emergency power function is tested to check if everything is working correctly.
- Explanation and aftercare: The professional explains the operation and demonstrates the app, which gives you real-time insight into charging status, production, and consumption. The average installation duration is 4 to 8 hours, depending on the complexity.
How can you save on a home battery?
There are several ways to reduce the costs for a home battery without compromising on quality.
- Calculate your payback period: Determine in advance whether a home battery is profitable by calculating the difference between the purchase and feed-in price, your self-consumption percentage, and the lifespan of the battery. This prevents you from investing in a system that does not pay for itself.
- Choose the right capacity: Do not buy too big or too small. A family with average consumption and 10 solar panels often has enough with 5-10 kWh. This avoids unnecessary costs for a battery that is too large.
- Consider a modular system: Choose a battery that can be expanded later if your energy needs grow or if you add more solar panels. This way, you don't have to pay the highest price immediately.
- Plan the installation during the week: Avoid weekend and urgency surcharges by scheduling the job well in advance. This easily saves several hundred euros.
- Prepare the workplace: Tidy up the installation location so that the professional can get to work immediately. This saves labour time and lowers the total installation costs.
- Book via Zoofy: You get a fixed rate in advance, without call-out charges and without surprises. You only pay after the job is completed.
