Calculate your estimated costs
This is an estimate based on average 2026 prices. Actual costs may vary. Always request multiple quotes for an exact price.
Cost factors
The total cost for a home battery usually consists of:
- Battery unit: 50-60% of the total
- Inverter: 20-25% of the total
- Installation and labor: 10-15% of the total
- Cabling and connection work: 5-10% of the total
These percentages can vary depending on the chosen capacity, brand, and installation complexity.
Why do prices vary?
- Capacity (kWh): Small batteries (3-5 kWh) cost €2,500-€4,500, medium (5-10 kWh) €4,000-€7,500, large (10+ kWh) €5,000-€9,000.
- Brand and quality: Premium brands like Tesla, LG, and BYD are more expensive but more reliable.
- Inverter type: Hybrid inverter or AC-coupled battery affects price (approx. €2,000 extra).
- Installation complexity: Location, meter cabinet upgrade, and cabling determine labor costs (€500-€1,000).
Subsidies & incentives
There is no national subsidy available for home batteries. However, there are provincial schemes and options for VAT refund and favorable financing.
