In the Netherlands, a record amount of solar energy was generated last year, but at the same time, that electricity yielded less for consumers than ever before. Due to drastic changes in the net metering program and the introduction of fixed feed-in rates by nearly all energy suppliers, it simply no longer pays to blindly feed excess solar energy back into the power grid. A home battery offers an immediate solution: it allows you to store the free electricity from your own solar panels for when you really need it.
But which brands perform best, what price range should you expect, and how do you choose the right system for your household?
When should you choose a home battery?
A home battery isn’t an impulse buy; it’s a deliberate step toward controlling your energy bills and making your home less dependent on the power grid. On average, a household with solar panels consumes only 30% of the electricity generated at the exact moment it’s produced. The remaining 70% flows back into the grid during the day, precisely when electricity prices are low and you’re charged for feeding power back into the grid. With a high-quality home battery, you can increase your self-consumption directly to 60% or even 80%.
You should consider a home battery especially in the following situations:
- You want to avoid feed-in charges right away: Energy providers charge hefty penalties for the electricity you feed back into the grid on sunny afternoons. By storing this electricity locally in your own battery, you can avoid this unnecessary expense on your annual bill.
- You’re preparing for the phase-out of the net metering program: Once the net metering rules change permanently on January 1, 2027, the electricity you feed back into the grid during the day will be worth only a fraction of the expensive electricity you purchase in the evening. Having your own energy buffer will then be the only way to protect the return on your solar panels.
- You want to take advantage of dynamic energy rates: Even on cloudy days or if you don’t (yet) have solar panels, a battery is cost-effective. Smart systems automatically charge when the electricity price on the energy market is low or even negative, and supply that cheap electricity to your home as soon as rates rise during the evening peak.
- You’re looking for peace of mind in the event of a power outage: Certain high-end storage systems come equipped with a full-fledged backup power supply. If the public power grid goes down, the system seamlessly switches to battery power, ensuring that your refrigerator, lights, and internet continue to function as usual.

The Anker Solix Solarbank Max AC
Modular storage is the latest trend for residential and small business users who don’t want to be tied to a single fixed system. The absolute pioneer in this field is the brand-new Anker SOLIX Solarbank Max AC.
This is the world’s first 7 kWh all-in-one plug-in home battery for existing solar panels, specially designed for easy installation without major modifications to your meter box.
Here are the key benefits at a glance:
- Maximum Efficiency: Thanks to its powerful bidirectional capacity of 3500W, you can utilize up to 99% of the solar energy you generate. Where other systems often fall short, this Anker gets the most out of your current setup.
- Flexible scalability: The base capacity of 7 kWh can be easily expanded to as much as 42 kWh thanks to a cable-free snap-in system.
- Smart dual-day modes: The AI-driven energy management system fully automates charging and discharging. A unique feature is the ability to set two different modes per day; this allows you to charge efficiently with solar power during the day and automatically switch to dynamic usage in the evening to take advantage of fluctuating electricity prices.
- Ready for the future: The system features a reliable backup function, a lifespan of up to 15 years, and works seamlessly with smart home integrations and dynamic energy providers.
The cost of a home battery
At Off Grid Power Station, we believe in transparency: with us, the investment in a home battery is always clearly broken down into the purchase of the battery and the inverter (if not already built-in), and professional installation by our own specialists. Although market prices have dropped significantly in recent years, we always work with you to carefully evaluate the balance between capacity and price. After all, you don’t want to pay for capacity you’ll never use.
Because we’re an official supplier of top brands and ship directly from our own inventory, we can offer competitive rates. Depending on your situation and brand preference, you can expect the following approximate prices from us:
- Small systems (3 to 5 kWh): On average, between €1,300 and €4,400. Ideal for covering the base load during the evening hours.
- Medium-sized systems (6 to 10 kWh): On average between €2,500 and €6,800. The most popular option for single-family homes.
- Large storage systems (15+ kWh): Starting at €3,700. Suitable for large homes, heat pumps, or fully off-grid applications.
Subsidies and VAT Refunds
In the Netherlands, there is currently no nationwide purchase subsidy for home batteries for private individuals. However, under certain conditions, you can claim a refund of the 21% VAT on the purchase and installation through the Dutch Tax Authority. This significantly reduces the net investment, and you’ll start saving money right from day one. Want to know exactly how this works and what you need to consider at the local level?

Frequently Asked Questions About the Best Home Batteries
What Is the Best Home Battery for Solar Energy
The best home battery for solar panels is a system that communicates quickly and accurately with your power generation. Brands such as HYXIPOWER and Sigen are specifically designed for this purpose. It’s important that the charging capacity of the battery inverter matches the peak power output of your solar panels. If your panels generate 5 kW at noon, the battery must actually be able to handle this power to prevent electricity from leaking back into the grid.
How do I determine the right capacity for my household?
A battery that’s too small fills up too quickly, while a battery that’s too large barely reaches a full charge during the winter months. To determine whether you need a battery capacity of, say, 15 kWh or a more compact model, you can use two simple rules of thumb:
- The 1-to-1.5 rule: Aim for approximately 1 to 1.5 kWh of battery storage per kWp of installed solar panel capacity. Do you have 6 kWp of solar panels on your roof? Then a battery capacity of 6 to 9 kWh is the most efficient choice.
- Nighttime consumption: Check your current energy provider’s app to see how much electricity you consume on average between 6:00 p.m. and 8:00 a.m. This is the exact amount of electricity your battery must be able to provide to remain fully self-sufficient during the hours when there’s no sunlight.
