“Our goal is a world in which everyone is able to cover their energy needs with decentralised and intelligent clean energy systems that generate and store energy locally.
We also create energy communities where everyone can connect to share energy where and when it’s needed. Ultimately this will emancipate our world from the dependence on fossil fuels and anonymous energy corporations and provide us with greater control over our energy future.”
Christoph Ostermann, CEO sonnen GmbH, Germany

How the sonnenBatterie

grants you independence.

The sonnenBatterie will store the surplus energy generated by your PV system in times when you don’t have any need for it. The stored energy from the daytime is then at your disposal throughout the night. But the sonnenBatterie is much more than just a battery, it’s an intelligent storage system that automatically adjusts the energy use so that most of your self-generated solar energy stays in your household.

Morning: minimal energy production, high energy needs.

At sunrise the solar panels start to produce energy, though not enough to cover the morning energy needs. The sonnenBatterie will bridge the gap with the stored energy from the previous day.

Midday: highest energy production, low energy needs.

In the daytime the solar panels’ energy generation is at it’s peak. But since nobody is home the energy consumption is very low so that most of the generated energy is stored in the sonnenBatterie.

Evening: low energy production, high energy needs.

The highest daily energy consumption is in the evening when the solar panels produce little or no energy. The sonnenBatterie will cover the energy needs with the energy produced in the daytime.

The key to your smart energy home.

The sonnenBatterie optimises your household energy consumption by storing excess solar electricity for use later.

Adding a sonnenBatterie to your solar power system enables you to

  • Maximise the use of your clean solar energy by storing excess solar
    for use when you need it

With sizes ranging from 2kWh to 16kWh, the sonnenBatterie will power a detached house, a multifamily house or a community of houses. Should your storage needs increase, you can easily expand the capacity of the sonnenBatterie in blocks at 2kWh. Should you ever require more power – for example if you are running a business – sonnen offers a variety of commercial pro systems that will suit you. Ask us about this today.

What sonnenBatterie is the right one for me?

With the sonnenBatterie eco and sonnenBatterie hybrid, we offer two intelligent storage solutions with very distinctive benefits. This enables you to choose the sonnenBatterie that best covers your energy needs.
Maximum flexibility: the sonnneBatterie eco.

If you value a high degree of flexibility the sonnebatterie eco is the right solution for you. It is not tied to the size or output power of a PV solar system. So no matter how much energy you plan to produce the sonnenBatterie eco will be the perfect addition to your personal energy solution.

You can easily connect it to your existing PV solar system or to any other energy sources such as wind generators.

The sonnenBatterie eco can be installed in both single phase and three phase households and can grow with your energy needs by adding extra battery modules at a later stage.

With the sonnenBatterie eco, you are eligible to take advantage of our sonnenFlat making you independent from traditional retailers, stabilising the grid and reducing your energy bills.

Amazingly economical: the sonnenBatterie hybrid.

The sonnenBatterie Hybrid stands for maximum economic efficiency. Since the energy that is generated by a PV solar system is a direct current, it needs to beconverted to an alternating current for you to be able to use it in your home. That’s why every PV solar system needs an invertor. The sonnenBatterie hybrid comes with an integrated invertor thereby eliminating the need for an external PV invertor. The total cost of the PV solar system and the sonnenBatterie is noticeably reduced by removing the cost of this component and its installation. Thus making the whole system more compact, more efficient and clean energy even more affordable for everyone. The hybrid can also be connected to existing solar with the option of plugging new solar directly into it further down the track.

Regardless of what sonnebatterie model you choose – we guarantee that you will get the best possible solution for your needs!

The sonnenBatterie eco delivers savings and peace of mind day and night.

Use solar energy during the day & at night.

The sonnenBatterie eco lets you enjoy the benefits of your solar energy production 24-hours a day. Our integrated smart electronics manage energy use throughout the day, detecting when there’s excess power, using it for large energy household items such as pool pumps or hot water systems. Resulting in better savings and reduced energy bills.

Harvest cheaper energy to use later.

sonnenBatterie eco allows you to engage in ‘price arbitrage’ or take advantage of time of use tariffs. The sonnenBatterie gives you the option to charge from the grid in off-peak times to reduce your peak electricity costs.

Never worry about the lights going out.

Electricity blackouts are quite rare in Australia and will usually only last a couple of hours at the most. Even so, these outages are always unpredictable and can cause problems.

With sonnen’s emergency power supply accessory – you are safe. It will reliably supply your household with stored energy during these power failures. Order a sonnenBatterie backup accessory as an option when buying your sonnenBatterie or upgrade to it later.

Gain energy autonomy.

A sonnenBatterie eco integrated with solar panels allows your home to produce and store 100 % of the energy it uses – depending on climate and sun exposure – enabling your home to be energy selfsufficient.

With the sonnenBatterie you will always have the latest technology built in one system. Through smart Z-wave, relay control and load management the sonnenBatterie can help you achieve the highest level of autonomy.

Keep an eye on your energy
supply and consumption:
with the sonnen app.

You probably know your energy consumption only as an abstract numeric value on your electricity bill. With the sonnen app and the sonnen online portal, you can find out how much energy you are consuming, how much power you are generating and how much energy is being stored in your sonnenBatterie. All in real-time with intuitive diagrams that will show you to what degree you are actually independent of your energy provider.

The sonnen app paired with smart plugs can help you increase that independance even further. For example, you can use the sonnen app to start your washing machine while you are not even home to use up any surplus energy from your solar system.

This shifts the source of the energy you use from your energy provider to your home produced energy thereby increasing your degree of independence. Enjoy true transparency with the sonnen app. Anywhere, anytime.

Just imagine you had the chance to take your energy future into your own hands.

Clean and affordable energy for everyone is the biggest challenge of our time. If we succeed to free our energy production from carbon-based emissions within the next ten years we will not only protect our environment but also our economical and political freedom.

For everyone everywhere.

The goal of sonnen is to enable easy access to renewable energy for everyone in this world. We are present in many countries in Europe, the United States and in Australia. With the sonnenBatterie you will join a globa l and rapidly growing community of people that share a common vision: independence from corporate energy providers and control of your own energy future.
