Intelligent, long-lasting and economical – the sonnenBatterie

The sonnenBatterie is a high-tech storage system that has proven itself in thousands of households – every day. The combination of a PV system and a sonnenBatterie will allow you to cover about 75% of your yearly energy requirement with self-produced and clean energy. Since your energy is being generated on your roof and not by some anonymous energy provider you are more independent than before. So take your energy future into your own hands and reduce your energy costs to a minimum. The decision for a sonnenBatterie is also a decision for the highest standards in safety and quality that "Made in Germany" stands for.

How the sonnenBatterie gets you through the day

Clean energy during the daytime, in the evening and at night.

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 energy generated from the solar panels is at its 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 need with the energy produced in the daytime.

What sonnenBatterie is the right one for me?

With the sonnenBatterie hybrid and the sonnenBatterie eco, 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 sonnenBatterie eco.

If you value a high degree of flexibility the sonnenBatterie eco is the right solution for you. It is not tied to the size or output power of a PV system. So no matter how much energy you plan to produce the sonnenBatterie eco will the perfect addition to your personal energy solution. You can easily connect it to various energy sources like wind generators, heat pumps or fuel cells. This makes the sonnenBatterie eco the perfect choice if you plan to upgrade your existing PV system. It can easily be hooked up to any power source you may be using and will immediately enable you to enjoy clean energy even at night. With the sonnenBatterie eco1, you are eligible to take advantage of our sonnenFlat. And don‘t forget: every single sonnenBatterie contributes to taking the strain off the public power grid.

Amazingly economical: the sonnenBatterie hybrid2.

The sonnenBatterie hybrid stands for maximum economic efficiency. Since the energy that is generated by a photovoltaic system is direct current it needs to be converted to alternating current for you to be able to use it in your home. That‘s why every PV system needs an inverter. The sonnenBatterie hybrid comes with an integrated inverter thereby eliminating the need for an external photovoltaic inverter. The total cost of the photovoltaic system and the sonnenBatterie is noticeably reduced by removing the cost of this component and its installation. This makes the whole system more compact, more efficient and clean energy even more affordable for everyone. With a sensational efficiency of 98,6 %, the sonnenBatterie hybrid ensures that the energy gets from your roof into your household almost without any loss. So that you can enjoy clean inexpensive energy when you need it.

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

Keep an eye on your energy supply: with the sonnenApp

With the sonnenApp you'll be able to check your energy usage and production - anytime and from anywhere. Use the sonnenApp on your smartphone or tablet to monitor, analyse and control the supply and demand of your household. 

The right size energy storage for any need – any time

Every household has its own very specific energy needs. That's why the sonnenBatterie was developed as a multi-stage storage system that can be adapted to the most diverse energy needs. With storage sizes ranging from 2 kWh to 16 kWh the sonnenBatterie will power a detached house, a multi-family house. The sonnenBatterie's energy capacity can be individually expanded in blocks of 2 kWh - should you ever feel the need to increase the power storage in your house.

Complete system.

High quality components perfectly tuned to your needs

The sonnenBatterie is a complete system - ready for connection. This means that inside of every sonnenBatterie you'll find not only the extremely durable battery modules but also an inverter, an intelligent energy manager, measurement technology and the software to operate it all smoothly. All in one handy box. In contrast to most other battery systems in the market, the sonnenBatterie components are build into a single high-quality casing and perfectly attuned to each other - thereby ensuring a very high longevity and maximum quality with a small footprint.
Cell type.

Batteries are the basis of all energy storage systems

Over time they will be charged and discharged many thousands of times. For that reason the sonnenBatterie is based on the most reliable and sustainable battery technology available and exclusively uses lithium iron phosphate batteries (LiFePO4). These batteries offer a greater longevity and higher safety than most other lithium-ion batteries that are commonly used in smartphones, laptops or electric cars. Did you know: lithium iron phosphate is the only battery component that occurs naturally and does not contain any toxic heavy metals.

More than the sum of the parts: independence for your business

Should you ever require more power - for example when you are running a business - multiple sonnenBatterie can be set up as a cascading cluster. Thereby increasing the capacity and power of the sonnenBatterie up to a maximum of 48 kWh. More than enough to satisfy the energy needs of your business.
