From purchase price to installation costs and payback period: everything about the true costs of a home battery in 2026, including subsidies and savings.
The price of home batteries has dropped by more than 40% over the past three years (source: BloombergNEF). In 2026, home batteries are more accessible than ever, but prices vary enormously depending on type, capacity, and installation method.
In this overview, we give you an honest and complete picture of the true costs, including installation, additional components, and the subsidies that reduce the investment.
The market has three main categories: plug-and-play batteries (self-installable), all-in-one systems with a built-in inverter, and high-voltage systems that require a hybrid inverter.
| Type | Capacity | Purchase price (incl. VAT) | Installation costs |
|---|---|---|---|
| Plug-and-play (Solarbank 2) | 1.6 kWh | ~€649 | €0 |
| Plug-and-play (Solarbank 3 Pro) | 2.7 kWh | ~€1,299 | €0 |
| All-in-one (SOLIX X1 5 kWh) | 5 kWh | ~€3,500 | €800–€1,200 |
| All-in-one (SOLIX X1 10 kWh) | 10 kWh | ~€5,200 | €800–€1,200 |
| High-voltage (Pylontech Force H3) | 15 kWh | ~€4,500 | €1,000–€1,800 |
The listed prices include VAT. Plug-and-play systems have no additional installation costs. All-in-one and high-voltage systems require professional installation (see hidden costs below).

Installation costs vary from €500 to €2,000 depending on complexity, region, and system type. A plug-and-play system has no installation costs. A high-voltage system requires a certified installer: expect €800 to €1,500 for an average installation.
If you don't yet have a suitable inverter, there are additional costs. A hybrid inverter costs €800 to €2,500 depending on brand and power rating. Some all-in-one systems (such as the Anker SOLIX X1) have a built-in inverter — this saves considerably.
A 10 kWh home battery delivers approximately €400 to €600 per year in savings at average usage (replacing grid electricity at €0.30/kWh). With dynamic charging and discharging via a dynamic energy contract, this increases to €800 or more per year.
The payback period typically ranges from 4 to 8 years, depending on system type, energy price, and usage profile. After the payback period, the savings are pure profit, given the 10–15 year warranty.
The ISDE subsidy (Investment Subsidy for Sustainable Energy) applies to home batteries purchased together with a heat pump or solar boiler. The 0% VAT regulation for solar panels and related systems (including home batteries) has been in effect since 2023 in the Netherlands — you pay no 21% VAT on purchase.
The best value for money is found in the mid-market: systems from €3,000 to €6,000 typically offer the shortest payback period per euro invested.
A home battery is a serious investment, but with current subsidy options, falling battery prices, and rising energy prices, the business case for most households with solar panels is strong. Get in touch for a personalised cost overview.
