Product

A plug-and-play home battery is a battery that can be easily connected via a standard wall outlet. The battery stores energy (for example from solar panels) so that you can use it later in your home.

No, that is not required. A home battery can also store energy from the electricity grid, for example when electricity prices are low. However, with solar panels you usually get more benefit from a plug-and-play home battery.

Most plug-and-play home batteries are easy to install:

  • Place the battery on a stable surface
  • Plug the battery into a wall outlet
  • Connect the battery to the corresponding app (if applicable)
  • Always check the manual for specific installation instructions

In most cases, no. Plug-and-play systems are designed so that you can connect them yourself. Please note, in most cases plugging the battery into a wall socket does not unlock the full potential. The wall sockets are limited to 800 W power. To maximase the potential you will need a separate group. If you do not have one left over in your electrical panel you can choose to contact a local electrician.

This depends on the model. Please check the product page for specifications.
Capacity is usually expressed in kilowatt-hours (kWh).

Most plug-and-play headhunts often start at a few kWh, you can expand them with additional battery modules to increase capacity.

With many systems, it is possible to connect multiple batteries together to increase the storage capacity.

Yes, but de safety of these products is always linked to how it's installed. Please follow the manufacturers instructions for installation carefully.

But don't worry, all of our modern home batteries are equipped with multiple safety systems such as:

  • Temperature control
  • Overload protection
  • Automatic shutdown in case of malfunctions

Some of them even have built in fire suppression features. Like some Zendure, Jackery and Anker models.

Our Anker SOLIX Solarbank MAX AC is one of the safest options available, featuring a built-in fire suppression system and 6 other safety features.

Preferably place the battery:

  • Close to a wall outlet (or solar panels if you want a direct connection)
  • Indoors or in a dry location
  • Out of direct sunlight
  • On a stable surface

Yes, absolutely. Our plug-and-play home batteries come with an app where you can monitor in real time:

  • How much energy you store
  • How much energy you use
  • How much energy you feed back to the grid

This depends on the model.
Some home batteries can automatically switch to backup power and continue supplying certain devices.
Other systems only function when the electricity grid is available.

Most modern home batteries last on average 10 to 15 years, depending on usage and the number of charging cycles.

For example, Zendure offers a 10-year warranty.

Key advantages include:

  • Easy installation
  • Increased use of self-generated energy
  • Lower energy costs
  • Less dependence on the electricity grid
  • The ability to trade energy with a dynamic energy contract

Yes — that is exactly the intention.
These batteries are designed to be connected via a standard wall outlet.

Always follow the installation instructions and use a properly functioning grounded outlet.

Savings depend on:

  • Your energy consumption
  • Electricity prices
  • Whether you have solar panels

Many users save money because they use their own stored energy later instead of buying electricity from the grid.

The payback period is usually around 5 years depending on how you use it.

Please note: it depends on factors such as:

  • Energy prices (and dynamic trading)
  • Battery capacity
  • How much of your own electricity you use

Our AI Chatbot can help you with this calculation. Feel free to ask away! It can help with many questions. If you would rather talk to one of us you can always reach us on whatsapp or through phone.

Most plug-and-play home batteries are virtually silent.
Some models have a small cooling fan, but the noise level is generally minimal.

Yes, a home battery uses a small amount of energy to manage the system and provide cooling if necessary.
This consumption is typically negligible.

Net Metering Scheme (ending 2027)

When the net metering scheme ends, the electricity you feed back into the grid can no longer be fully offset against your own consumption. As a result, you will usually receive a lower compensation for returned electricity, and feed-in charges may even apply. This is the perfect time to consider purchasing a plug-and-play home battery.

A plug-and-play home battery makes it possible to store excess solar energy instead of feeding it back into the grid. This allows you to use the stored energy later, for example in the evening or at night, and reduces your dependence on the electricity grid.

More and more energy suppliers are charging fees for feeding electricity back into the grid. With a home battery, you can store a large portion of the energy you generate and use it later, meaning you feed less electricity back to the grid and therefore pay lower feed-in costs — a win-win situation.

In many cases, a home battery allows you to use a large portion of the energy you generate yourself. The exact amount depends on:

  • The battery capacity
  • Your energy consumption
  • The amount of solar energy you generate

Solar panels will remain attractive even without the net metering scheme, but a home battery can significantly improve the return on investment. By storing energy, you can use more of your own electricity instead of feeding it back to the grid for a lower compensation.

Yes. When net metering disappears, it becomes financially more attractive to store your own energy and use it later. A plug-and-play home battery helps increase your self-consumption of solar energy.

Yes. By storing energy when your solar panels produce a lot of electricity and using it later, you need to buy less electricity from the grid. This can help reduce your energy costs.

Many households choose a plug-and-play home battery to be better prepared for changes in the energy market, such as:

  • The end of the net metering scheme
  • Rising energy costs
  • Increasing energy independence
