You're probably already noticing it in the news and at the dinner table: the Netherlands is covered in solar panels, but the power grid is increasingly under strain. Precisely when you're finally gaining more control over your own electricity, feed-in tariffs and the reduction of the net metering scheme suddenly become highly relevant.
That's why many households in 2026 are asking the same question: does a home battery make sense for my situation, and which type best suits my existing solar panels? Those who want to delve deeper into this can also read our comprehensive guide to buying a home battery in 2026.
In this guide, we clearly explain how a home battery for solar panels works, why self-consumption is becoming increasingly important, and why a flexible AC-coupled home battery is the logical step for many existing installations.
What is a home battery and how does it work?
A home battery is an electricity storage system. It stores the power your solar panels generate during the day, but which you don't immediately use at that moment. Instead of that surplus going straight back to the grid, you use that energy yourself later.
In practice, this usually works in three steps:
- Charging during the day: your solar panels produce electricity and the surplus is stored in the battery.
- Using it later: in the evening or at other times of higher consumption, you first use your stored energy.
- Smarter control: with a smart meter and energy management, you can better coordinate when you charge, discharge, or feed back into the grid.
For many households, the value of a home battery is therefore not just about storage, but primarily about increasing self-consumption, reducing dependence on expensive evening electricity, and less feeding back at unfavorable times.
Why a home battery is becoming increasingly relevant in 2026
The market has changed. While storage was mainly interesting for early adopters a few years ago, in 2026, more and more households are looking at a home battery as a practical addition to their solar panels.
1. Less certainty about net metering
The net metering scheme runs until December 31, 2026, but will stop from 2027. This makes it more important to use more of your own solar power yourself instead of relying on feeding back into the grid. Read more at the Dutch government.
2. Feed-in tariffs impact the benefits of solar panels
More and more energy suppliers charge costs for solar power fed back into the grid. This makes it more attractive to keep surpluses at home and use them yourself later. Those who want to delve deeper into this can also read our page on avoiding feed-in tariffs with a home battery.
3. Dynamic energy prices make timing more important
With a dynamic contract, the electricity price changes every hour or every quarter of an hour. A smartly controlled battery can then help to better manage cheap and expensive moments. This does require a system that works well with your consumption data and smart meter. Also, read our article on smart management with dynamic energy prices.
The common thread is simple: the less you have to feed back into the grid and the more you can smartly shift consumption over time, the more interesting a home battery becomes in practice.
Types of home batteries: hybrid system or AC-coupled retrofit?
Those looking to buy a home battery usually end up with two options: a hybrid system or an AC-coupled home battery. For households with existing solar panels, this distinction is important.
| Feature | Hybrid system | AC-coupled (retrofit) |
|---|---|---|
| Installation | Often more extensive, especially with existing systems | Often easier to add alongside an existing inverter |
| Suitable for | New installations or full replacement | Existing solar panel installations |
| Modification of current setup | Often more work on inverter and system structure | Preservation of existing solar panels and inverter |
| Flexibility | Less flexible for retrofit | Interesting for gradual expansion |
Hybrid system
A hybrid inverter combines solar panels and battery storage in one system. This can be logical for a completely new installation, but less attractive if your current inverter is still working well.
AC-coupled home battery
An AC-coupled battery connects to your existing installation without needing to rebuild your entire solar panel system. For many households with existing panels, this is the most practical retrofit route.
If you want to better understand how such a system relates to your meter cupboard and grid connection, read our article on connecting a home battery to 1-phase or 3-phase.
The smart choice for existing solar panels: Sunpura S2400 AC
The Sunpura S2400 AC is developed for households that want to make smarter use of their existing solar panels. Instead of replacing your current system, you add storage as a retrofit solution.
The basic configuration starts with 2.4 kWh storage capacity. For many households, this is a logical entry point, as you gain insight into your consumption pattern before dimensioning larger.
Additionally, the S2400 AC is interesting for those who want to manage based on smart meter data and P1 port insights. This allows you to better coordinate when you charge, discharge, and cover household consumption.
Key product features include LiFePO4 cells, an IP65 housing, support for dynamic tariffs, a basic capacity of 2.4 kWh, a nominal system voltage of 48 V, and a single device power rating of 2400 W.

- • Retrofit solution: fits existing solar panel installations.
- • Capacity: 2.4 kWh base module, expandable within the S2400 AC platform.
- • Power: 2400 W nominal power per device.
- • Smart control: support for smart meter data and dynamic tariffs.

What does a home battery cost and what determines its profitability?
The cost of a home battery varies greatly depending on the situation. Not only the battery itself counts, but also installation, control, grid connection, and the question of how much of your electricity you can actually use yourself.
In 2026, the business case usually depends on four things:
- Your own consumption profile: how much electricity do you use specifically in the evening or early morning?
- Your feed-in: do you often feed large surpluses back into the grid on sunny afternoons?
- Your contract type: fixed, variable, or dynamic makes a big difference in practice.
- Your system setup: a simple retrofit solution can limit installation work.
A home battery therefore does not automatically provide the same benefits for everyone. In many cases, storage becomes more interesting the more solar power you have left over, the more often you feed back into the grid, and the smarter you can manage your consumption.
| Scenario | What's happening? | Chance of benefit |
|---|---|---|
| Low surplus | You already use a lot directly during the day | More limited, mainly depends on timing |
| Average household | Surplus during the day, more consumption in the evening | Often interesting for more self-consumption |
| Dynamic contract | Hourly price differences play a stronger role | Interesting with smart control, but not without risk |
Those who only look for the lowest purchase price often miss the bigger picture. Those who consider ease of installation, control, and future-proofing gain a more realistic view of the profitability of a home battery.
Does a home battery suit your situation?
A home battery is particularly interesting if you already have solar panels, regularly feed back into the grid during the day, and use more electricity in the evening than you generate directly. If you also have insight via a smart meter or P1 port, then smart control becomes even more valuable.
For many Dutch households in 2026, the choice is no longer just about "whether or not to get a battery," but about which system best suits their existing installation, consumption, and energy tariff.
Do you already have solar panels and want to add storage without rebuilding your entire system? Then an AC-coupled solution like the Sunpura S2400 AC is the most practical route for many situations to start small and grow later.
