A home battery stores the power your solar panels generate during the day, so you can use it later.
A battery can also purchase power at the most favorable times when using a dynamic energy contract. This tool is AI-powered for most brands.

When the sun shines, your solar panels often produce more energy than you use at that moment. The home battery stores this excess solar energy. In the evening or when there's little sun, your home automatically uses the stored energy. This means you need to draw less power from the grid, saving you money on your energy bill.
With the right home battery, you'll no longer feed power back into the grid. Your self-generated power will be used when you need it.

With a home battery, you use more of your own green energy, save costs, and become less dependent on the energy grid.

It's best to install a home battery in a safe and well-ventilated location, such as a garage, basement, or utility room. This location ensures optimal operation and a longer battery lifespan.
Ideally, have the battery installed near the inverter or meter box to minimize energy loss. Some models can also be installed outdoors, provided they are weatherproof and protected from extreme temperatures.
We at AboutWatt are happy to advise you on this!

The price of a home battery depends on the brand, the capacity (kWh), and the installation costs. On average, a home battery costs between €4,000 and €10,000, including installation.
There is a cheaper alternative in the form of Plug & Play batteries , these are compact batteries that cost an average of €1,000 to €4,000 including installation.

The final price also depends on:

• the brand (e.g. Anker Solix, Sigenergy, Huawei or Marstek)
• the battery type (lithium-ion or alternative);
• whether you combine the battery with solar panels or an existing installation.
• possible subsidies or premiums in your region.

A home battery is generally not dangerous, as long as it's installed and used correctly. Most modern home batteries are equipped with multiple safety mechanisms that prevent overheating, overcharging, or short-circuiting.

In addition, they are extensively tested and certified according to European safety standards.

Always have the installation carried out by a certified installer – this is not only safer, but also necessary to maintain the warranty and insurance.

A backup function with a home battery ensures you still have electricity during a power outage . The battery then temporarily supplies power to essential appliances in your home, such as lights, refrigerators, or Wi-Fi modems.

Not every home battery has a backup function as standard; sometimes additional equipment is required, such as a special inverter or emergency power module.

In short: with a backup, your home will continue to receive (partial) power, even if the grid goes down. Without a backup, the battery only works when there's power from the grid.

AboutWatt's range of plug & play batteries and home batteries offers various backup options. Feel free to request a free consultation if you're unsure whether you're making the right choice!
