They say: ‘It’s time to declare your independence’. We agree.

They’re warrantied for 10 years and you can build them up to 15kWh of useable storage (always check the useable v actual storage) – enough to power an average home for more than a day if the sun starts hiding. The Sonnen system stands out as a really flexible high quality option. With everything connected to the internet you also get automatic software updates, keeping everything efficient while you go and tend to the garden, or read a book, or run your business. In other words, once installed, you don’t have to do anything.

Which sonnenBatterie is right for me?

There are two solutions for homeowners:  the sonnenBatterie eco and the sonnenBatterie hybrid.  For commercial premises, the more powerful sonnenBatterie pro is the right solution. Find out which model suits you best!

Ultra Flexible – the sonnenBatterie eco

The sonnenBatterie eco is the perfect solution for those wanting the greatest possible flexibility. Since it is not bound to any particular photovoltaic system size, its modular design makes it the right companion for you.

It can be easily connected to other power sources and is compatible with a mini wind turbine or a fuel cell. The  sonnenBatterie eco is also ideally suited if you already have a solar system. It connects easily to existing installed systems enabling you to enjoy solar power day or night.

Cost-efficient – the sonnenBatterie hybrid

The sonnenBatterie hybrid provides better cost-efficiency as the system also includes the inverter for your solar system.  This eliminates the need for an external device to convert direct current (DC) from the roof into alternating current (AC) for your house.

The hybrid significantly reduces the total cost of a solar power set up, saves space and runs more efficiently. Solar power reaches your household with almost no losses.

Always ready – the sonnenBatterie pro

The sonnenBatterie pro is the new standard for responsible energy consumption in commercial operations. It offers maximum self-sufficiency, capacity and performance. Since companies require more energy than a typical single-family home, three sonnenBatteries can be combined to form a larger capacity storage solution. Offering higher performance and capacity, the sonnenBatterie pro is ideal for large commercial solar arrays. Thanks to the integrated energy manager with weather  forecasting and estimated charging, your company can achieve efficient and transparent supply of clean power at all times.
