Best plug-in home battery 2026: which one suits you?

Last updated: 21 October 2026 · By Team Multi-Solar, home batteries since 2022, Rotterdam

There is no single best plug-in home battery for everyone: it depends on your consumption, your panels and what you want to keep running during a power cut. For an average family with solar panels, about 5 kWh fits. If you want to start small, want backup power or want to connect panels directly to the battery, a different model suits you. Below are eleven models and the best choice per situation.

How do the plug-in batteries compare in one table?

These are the plug & play batteries we currently sell, with the manufacturer's data. Reference date 21 October 2026. A dash means the manufacturer does not specify it in the data we have.

EcoFlow STREAM AC 5000 5.02 kWh – 800 W / 2,500 W 2,500 W no IP65 10 years

The second power figure only applies if an installer puts the battery on a dedicated circuit, or if the manufacturer unlocks the higher power after inspection. Backup power always applies to the appliances on the backup power output, not to the whole house.

Why is there no best plug-in home battery for everyone?

Because the models win on different points. The Anker Max AC has the most capacity per unit and the highest backup power output in the table. The SigenMate and the Zendure 2400 Pro take the most solar panels directly. The Venus A starts the smallest. A battery that is strongest on one point is rarely the strongest on all points.

That is why we do not give a top three, but look at five questions:

  1. How much electricity do you use in the evening and at night? An average Dutch household (2,430 kWh per year, Milieu Centraal) uses about 3 to 5 kWh in the evening and at night. More storage than you can then deliver makes little sense. Work it out in how many kWh of home battery you need.
  2. Will you stay with the wall socket or will there be a dedicated circuit? In the Netherlands a battery may deliver a maximum of 800 W to your house via a standard wall socket. Over a 10-hour night that is at most 8 kWh, in practice often 2 to 4 kWh, because a house draws 200 to 400 W at night. More power is only possible on a dedicated circuit. Read the 800 watt rule and registration.
  3. Do you want backup power? Not every output is equally powerful, and no plug-in battery keeps the whole house running.
  4. Do you have panels without their own inverter? Then you are looking for a model with MPPT inputs.
  5. Where will it be placed? Indoors, in the shed or outdoors: the IP rating helps decide that.

Which plug-in home battery suits your situation?

Which plug-in battery if you want to start small?

Choose a modular model with a small base. The Venus A starts at 2.12 kWh and grows with separate modules up to 12.72 kWh. The Zendure SolarFlow 2400 AC+ starts at 2.4 kWh and, with AB3000L batteries of 2.88 kWh, goes up to 16.8 kWh. The SigenMate starts at 2.68 kWh, the HYXi HALO at 3.01 kWh. Note: with a module the storage grows, the power usually does not. Which module belongs to which model can be found among the expansion modules.

Which plug-in battery for an average family with solar panels?

A battery of around 5 kWh absorbs the afternoon surplus and covers a large part of the evening. The Venus E 3.0 is our most popular choice: 5.12 kWh, connected in about 15 minutes without an installer, and expandable later with a second battery. Comparable 5 kWh models are the Growatt Aura 5000 and the EcoFlow STREAM AC 5000. If you want slightly more in one unit, the AEG Solarcube Pro has 6.0 kWh, but it cannot be expanded. If you are in doubt between brands, read Marstek or Zendure.

Which plug-in battery if you want backup power?

Look at the power of the backup power output and how quickly it switches over. The Anker Max AC delivers 3,680 W and switches over within 10 ms. The Venus E 4.0 delivers 3,000 W, also within 10 ms. The AEG Solarcube Pro has a separate off-grid output of 3 kVA. In all cases, only the appliances connected to that output keep running. If you want the whole house to keep running, you need a fixed battery with a changeover device. The three levels are described in backup power with a home battery; fixed systems can be found among the fixed home batteries.

Which plug-in battery if you want to connect solar panels directly to the battery?

Then you need MPPT inputs, so that the panels connect to the battery without their own inverter. The SigenMate 2700 Ultra has four MPPTs, 4,000 W combined, for up to eight panels. The Zendure SolarFlow 2400 Pro has four MPPTs of 750 W each, 3,000 W combined. The Venus A has four MPPTs totalling about 1.4 kW. The other models are AC-coupled: they sit alongside your existing inverter. The Growatt Aura does have an AC port to which you can connect a micro-inverter.

Which plug-in battery with a dynamic energy contract?

Then what counts is how quickly the battery charges during the cheap hours. Via a standard wall socket this is slower than on a dedicated circuit. The Anker Max AC charges at 3,500 W on a dedicated circuit and, according to Anker, works with Tibber, EnergyZero and Frank Energie. The Venus E 4.0 schedules charging based on weather forecasts and energy prices and is ready for Frank Energie. The Venus E 3.0 has an AI mode for dynamic tariffs. How smart charging works is explained in home battery and dynamic energy contract.

Which plug-in battery can you place outdoors?

Ten of the eleven have IP65 or IP66 according to the manufacturer and may be placed indoors and outdoors; for the Venus A the IP rating is not in our data. IP66 is better protected against water jets. That applies to the Anker Max AC (with active heating, from -20 to 55 °C), the HYXi HALO, the AEG Solarcube Pro, the Growatt Aura and the SigenMate. The Venus E 3.0 and 4.0, the Zendure 2400 series and the EcoFlow STREAM, which heats itself in the cold, have IP65. With Zendure, the off-grid socket is not waterproof during use, according to the manual. Always have the location assessed by an installer. You can read more about fire safety in home battery safety.

What do you arrange after choosing a plug-in battery?

  • Meter. The battery is controlled via a P1 smart meter dongle (P1-meter) on your smart meter, or via a CT clamp in the electrical panel. Which one you need is explained in P1 meter or CT clamp.
  • Registration. In the Netherlands, register the battery with your grid operator via energieleveren.nl, and update the registration if you expand later.
  • More than 800 W or multiple batteries. A dedicated circuit is installed by an installer, about an hour's work (installation via quote). With multiple Marstek batteries, inspection by a qualified electrician is mandatory, according to Marstek. Zendure only unlocks the 2,400 W after an electrician has checked your wiring.

Frequently asked questions

Which plug-in battery has the most capacity?

Per unit, the Anker SOLIX Solarbank Max AC with 7 kWh, expandable to 42 kWh. The Venus E 3.0 goes up to 46.08 kWh, but then with nine batteries and the Marstek SmartBox, spread across three phases.

Is a bigger plug-in battery always better?

No. Via the wall socket every battery delivers a maximum of 800 W. If you have more storage than you can deliver in the evening and at night, part of it remains unused. Choose based on your consumption first, then on power.

Can I connect a plug-in battery myself?

Yes, by plugging it into an earthed wall socket, up to 800 W. For a dedicated circuit, more power or multiple batteries, you call in an installer.

Which plug-in batteries work without solar panels?

All models in the table can also charge from the grid. This is especially useful with a dynamic contract: charging at cheap hours, delivering at expensive hours.

What is the difference between a plug-in battery and a fixed home battery?

You connect a plug-in battery yourself to a wall socket, with a maximum of 800 W. A fixed battery is connected to the electrical panel by an installer, with more power and backup power for the circuits you choose during installation. Everything at a glance in plug-in or fixed.
