The energy market is changing faster than ever. Now that the net metering program is under pressure and energy suppliers are increasingly charging fees for feeding electricity back into the grid, the question is no longer whether you should get a home battery, but which one. The choice between a traditional home battery and an innovative plug-in home battery—also known as a plug-in home battery—determines how quickly you’ll recoup your investment and how much control you’ll actually have over your energy bill.
At Off Grid Power Station, we’re happy to help you make the right choice for your situation. Based on an independent comparison, we offer personalized advice that’s fully tailored to your personal consumption and living situation.
What is the difference between a traditional home battery and a plug-in home battery?
To make the right choice, it’s important to understand how the two systems differ technically. Although the goal is the same—storing solar power for later use—the way they achieve it is completely different.
- Traditional home battery: A powerful, permanent installation that is fully integrated into your utility panel via an AC connection. This requires a certified installer and modifications to the circuit panel. Ideal for those seeking maximum capacity and who own a permanent residence.
- Plug-in home battery: The new standard in flexibility. Systems like the Anker SOLIX Solarbank Max AC can be set up in just a few minutes by plugging them into a standard outlet. Perfect for those looking to save money quickly, renters, and DIY enthusiasts.
The Anker SOLIX Solarbank Max AC acts as a smart gateway that you can easily connect to your existing solar panels yourself. Using the accompanying app, you decide when the battery discharges, giving you maximum control over your own solar power without having to reach for a screwdriver to tinker with the meter box.
Compare all specifications: capacity, power, and efficiency
Specifications | Traditional Home Battery | Plug-in (Anker SOLIX) |
Installation | Professional (installer required) | Plug-and-play (self-installation) |
Storage capacity | 5 kWh to 20+ kWh | 7 kWh (expandable to 42 kWh) |
Max. output | Often higher (3 kW – 10 kW) | Up to 3,500 W |
Efficiency | 85%–95% | Up to 99% (at peak utilization) |
Warranty | 10 years | 10 years (15-year service life) |
Mobility | Fixed (moving is difficult) | Portable (easy to take with you) |
Which figures are most important to you depends heavily on your living situation. For large families and owner-occupied homes, total power output and high capacity are particularly important. If the heat pump, induction cooktop, and washing machine are all running at the same time, you need a system that can consistently deliver this high power output. For first-time homeowners, renters, and those looking to save money, it’s all about efficiency and simplicity. Often, a permanent installation in an apartment or rental home isn’t an option due to requirements from the homeowners’ association or landlord. The Anker SOLIX Solarbank Max AC is unique because, thanks to its 3,500W bidirectional input, it loses virtually no solar power during the midday peak. This high efficiency ensures that you can reduce your energy bill faster, even with a smaller system.
Installation and Safety
Your choice of a home battery determines whether you’ll need an installer to come to your home or whether you’ll start saving money yourself within minutes. While some people prioritize a technical transformation, others focus on immediate ease of use.
How do you install a home battery?
Permanently installing a battery is a job for a professional. A certified installer connects the system to its own circuit in the utility panel and often links it directly to your inverter. This process can take half a day and requires the necessary technical adjustments.
With a plug-and-play system, such as the Anker SOLIX Solarbank Max AC, you’re the installer. Thanks to the plug-and-play design, you simply connect the cables from your solar panels to the battery and plug it into an outlet. No tools, no installer—done in 5 minutes.
Safety and Regulations
A stationary battery must meet strict NEN 1010 standards, and you’re often required to notify your home insurance provider. A plug-in system like the Solarbank Max AC is considered a standalone device (just like your washing machine). That makes things much simpler, both legally and for your insurance.
Safety is a top priority for both systems, but the design differs. The systems we supply at Off Grid Power Station use LiFePO4 technology. Unlike older battery types, this technology is extremely stable and cannot catch fire if it overheats.
A plug-in system is virtually maintenance-free. A fixed system requires occasional technical checks by the installer.
How much does an Anker SOLIX Solarbank Max AC cost? And how quickly will you recoup your investment?
The cost of a home battery has dropped significantly in recent years, but the way you recoup your investment has changed. With the gradual phase-out of the net metering program and the introduction of feed-in tariffs, smart energy storage is more financially attractive than ever.
What do you get for your money?
Feature | Traditional home battery | Plug-in (Anker SOLIX) |
Purchase price | €4,000 – €8,000 | €2,499.00 |
Installation costs | €1,000 – €2,000 | € 0 |
Total investment | €5,000 – €10,000 | €2,499.00 |
Payback Period (average) | 10–14 years | 3.5 years (under ideal conditions, in as little as 2.5 years) |
The Anker SOLIX Solarbank Max AC significantly lowers the barrier to energy storage. While a traditional system often costs thousands of euros in installer fees and meter panel modifications, the Solarbank Max AC is a one-time investment with no hidden costs.
Cost-Saving Scenarios
The payback period for your home battery depends heavily on your energy contract and your consumption profile.
- Scenario 1: Dynamic Energy Contract
Do you have a dynamic contract? The Solarbank Max AC’s smart software charges the battery when electricity prices are low or even negative. You use this free electricity in the evening when prices peak. In this scenario, you’ll often recoup your investment within just a few years. - Scenario 2: Net Metering Phase-Out and Feed-in Tariff Fees
Does your supplier charge you feed-in fees for your solar panels? By storing your generated power directly in a home battery, you prevent it from feeding into the grid. You immediately save on the penalty fees charged by suppliers and increase your own consumption. - Scenario 3: Without Solar Panels
Even without solar panels, the Solarbank Max AC can be cost-effective. By using only the cheapest hours on the energy market (off-peak charging), you significantly lower the average price per kWh in your household.
Subsidies and VAT
Although there will be no national subsidy available for home batteries in 2026, the tax benefit remains significant. You can still claim a refund of the 21% VAT from the Tax Authority, provided you meet the requirements. As a result, the total cost of a home battery is often lower in practice.
Which home battery is the best fit for your situation?
The best choice depends mainly on your living situation and how flexible you can and want to be. Do you live in an apartment, a rental home, or are you just starting out in the housing market? If so, a plug-in home battery is the most logical choice. Since you don’t have to drill any holes or modify the circuit breakers in the utility panel, you don’t need permission from a landlord or homeowners’ association. The big advantage: planning to move? Just unplug it and take your investment with you to your next home.
Are you planning to expand your family or, for example, switch off your gas supply entirely? A plug-in system like the Solarbank Max AC is modular. That means you can start small today and easily add extra battery modules later.
Do you own your home long-term, have a heat pump, and drive an electric vehicle? If your electricity consumption is high and constant, a traditional fixed home battery is often the best option. These systems are fully integrated into your utility panel and are built to handle the heavy peaks of a modern household. It’s a robust, long-term investment in your home’s value.

Frequently Asked Questions About Traditional and Plug-in Home Batteries
Can I really install a plug-in home battery myself?
Yes, that’s the biggest advantage. While a traditional battery requires a certified installer and modifications to the meter box (NEN1010), a plug-in system like the Anker SOLIX Solarbank Max AC is up and running within 5 minutes. You simply snap the panels into place, plug it into an outlet, and you’re all set.
Does a plug-in battery also work with microinverters?
The Solarbank Max AC is specifically designed to work seamlessly with your existing PV system and microinverters.
What about feeding power back into the grid and net metering?
With a home battery, you can reduce the amount of electricity you feed back into the grid. This is crucial now that the net metering program is being phased out and energy providers are charging fees for feed-in. You store your own surplus electricity for the evening, instead of feeding it back into the grid (at a cost).
Which plug-in home battery is recommended?
The clear frontrunner right now is the Anker SOLIX Solarbank Max AC. This system not only offers enormous capacity (modular up to 42 kWh), but also features AI software. The system automatically optimizes charging and discharging.
How much maintenance does a home battery require?
Maintaining a home battery requires very little effort. The systems are completely sealed and virtually maintenance-free. The main “monitoring” is done through the accompanying app. There, you can view your energy usage and the status of your cells in real time, and you’ll automatically receive software updates.
Is a home battery covered by my regular insurance policy?
For homeowners, a home battery is usually covered under home insurance, just like solar panels. For a traditional battery, insurers often require an installation report. A plug-in battery is often considered personal property (like a washing machine), which makes insurance much simpler.
What happens if I move?
This is a crucial difference between plug-in and fixed batteries. A traditional battery is part of your home, and you can’t just take it with you when you move. A plug-in battery can be unplugged from the outlet, taken to your new address, and plugged back in within a few minutes.
