A practical guide to choosing the right home battery
Are you considering purchasing a home battery?
Perhaps you already have solar panels and wonder what you can do with the power you generate during the day. Or you are looking for greater energy independence, want to reduce your energy bill, or are interested in making smarter use of fluctuating energy prices.
Whatever your reason, choosing a home battery is about much more than just determining how many kilowatt-hours you need.
The right system depends on your home, your energy consumption, your solar generation, your energy tariff and your future plans.
En een thuisbatterij kan steeds meer dan alleen zonne-energie opslaan. Met de juiste technologie en het juiste energiecontract kan de batterij ook automatically respond to electricity prices and participate in energy trading, allowing you to make better use of the energy market.
How do you choose the right home battery?
This guide covers the key questions to consider before investing in battery storage.
What does a home battery actually do?
Het basisprincipe is eenvoudig. Uw zonnepanelen wekken overdag elektriciteit op. Uw huishouden heeft niet altijd meteen alle stroom nodig, zeker niet als er niemand thuis is.
Instead of feeding all that surplus electricity back to the grid, a home battery can store some of it.
Later, when your solar panels generate less or no electricity, you can use the stored energy in your home.
This can your own consumption of solar energy increase and reduce your dependence on grid electricity.
Charging from and discharging to the electricity grid
With smart energy management, your battery may be able to decide for itself when it charges, when it discharges and when it feeds electricity back, based on factors such as your solar generation, your household consumption and electricity prices.
As a result, a home battery is less a simple storage device and more part of an intelligent energy system for your home.
How large should a home battery be?
Overweegt u een thuisbatterij, maar weet u niet welke capaciteit u nodig heeft? U bent niet de enige. Een van de belangrijkste beslissingen bij het kiezen van een home battery is selecting the right storage capacity.
The capacity of a battery is measured in kilowatt-hour (kWh).
For example:
- A 5 kWh home battery can theoretically store up to 5 kWh of energy.
- A 10 kWh battery can store twice as much.
- A 15 kWh battery offers even more storage for homes with higher energy consumption or a larger solar installation.
However, bigger does not automatically mean better.
Are you choosing 5 kWh, 10 kWh, 15 kWh or more? The right battery capacity is the one that matches your energy consumption, your solar generation and your usage pattern. Your solar panels, electricity consumption, energy tariff, electric car, heat pump, future plans and even the way you use power during the day can all influence which system suits your home.
In this guide, we explain how Novectra can help you determine the right battery capacity and make the right choice.
What does a home battery cost?
The cost of a home battery depends on much more than the battery itself.
A complete battery installation can consist of the battery modules themselves, an inverter, energy management equipment, electrical protection, cabling, mounting materials and professional installation and commissioning. Depending on the home and system, additional electrical work may be required. If you want backup power, additional equipment may also be needed.
Therefore, comparing batteries purely on price per kWh can be misleading.
Two systems with the same nominal capacity can differ greatly in performance and functionality. One system may have higher usable capacity, better efficiency, higher power or more advanced energy management. The other may offer better expandability or a longer performance guarantee.
Bij het vergelijken van systemen is het daarom verstandig om naar de complete oplossing te kijken in plaats van alleen naar de prijs van de batterij.

Why professional installation of a home battery is important
A home battery is not simply a product you plug into the socket.
The battery becomes part of your home’s electrical infrastructure and must work together with your solar panels, inverter, electrical installation and energy management system. If you also have an electric car, heat pump or dynamic energy contract, those elements are part of the same equation.
Correct installation, configuration and commissioning are essential for a reliable and safe system. The technical design can have a major impact on how effectively the system performs.
How Novectra helps you choose the right home battery
At Novectra we believe a home battery should be designed around the way you actually use energy. Instead of starting with a catalogue of battery sizes, we start by understanding how your home generates and consumes power.
When technical installation company we combine energy advice with practical technical and installation expertise. We review your energy consumption and map when and how much power you use. We then look at your solar generation and how much surplus energy can realistically be stored and used. We also take future needs into account. Perhaps you are considering an electric car, a heat pump, additional solar panels or other electrical upgrades. All these plans can influence the right system design.
We also look at smarter energy options. If you are interested in a dynamic energy contract, automated charging and discharging or energy trading, these wishes can be incorporated into the system design from the outset.

Frequently asked questions (FAQ)
A home battery can be worthwhile if you want to use more of your own solar energy, reduce your dependence on the electricity grid or benefit from fluctuating electricity prices. Whether this is financially attractive depends on factors such as your energy consumption, the yield of your solar panels, your energy contract, battery capacity and installation costs. It is therefore important to calculate the potential savings based on your specific situation, rather than looking only at the price of the battery.
Novectra maps your energy situation, explains your options and advises you on the home battery that best suits your needs.
A home battery can usually be installed in a garage, utility room, basement, technical room or another suitable indoor or outdoor location. At Novectra, we assess your home and energy system to determine the most suitable location for your battery. Our specialists take factors such as safety, accessibility and the technical requirements of the system into account, so your home battery is installed correctly and efficiently. Want to know where a home battery can be installed in your home? Contact Novectra for personal advice.
Most modern home batteries are designed for a lifespan of approximately 10 to 15 years, although actual service life depends on factors such as battery technology, usage, the number of charge and discharge cycles and operating temperature. At Novectra, we help you choose a home battery with the right balance of performance, reliability and long-term value.
