A home battery in a Dutch house: the end of the chain
A battery sits at the end of the chain: insulate, size solar to your own use, then consider storage. Netzy offers one fixed home battery publicly: 5 kWh storage with 3 kW power for €2,995 including VAT.
Why small and fixed
A smaller system with high self-consumption needs less storage. We keep one fixed, honest offer instead of selling the biggest battery on the market.
Frequently asked questions
What does a home battery cost at Netzy?
The fixed public offer is 5 kWh / 3 kW for €2,995 including VAT. Other configurations only after a calculation for your specific house.
Netzy calculates what is technically feasible and what it costs, and explains the schemes. We do not give mortgage advice and do not broker mortgages. What you personally can borrow, and at what rate, is assessed by a mortgage adviser or lender. Label outcomes are route indications, never a guarantee.
