Never worry about the lights going out.

Solar power generation does not have to go to waste. When the grid goes down – with Black Start function, you can rest assured knowing that during the blackout, the sonnenBatterie hybrid 9.53 can restart itself after a full shut down, and utilise the energy from the directly connected solar system, to ensure you have continuous backup energy supply. Meaning you can use your essential appliances without interruption during times of extended blackouts**.

Locally made here in Australia

We are proud to have our pioneering sonnenBatterie hybrid 9.53 certified Australian Made in Elizabeth, South Australia.

In November 2018 sonnen opened our manufacturing plant in South Australia, dedicated to building safe, reliable home battery storage systems and accessories. The combination of 10 years of German innovation in design and engineering, along with local production expertise in Australian manufacturing has helped us deliver thousands of quality and intelligent home battery storage systems across Australia and New Zealand.


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.


Safety at the heart of every system

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.

The sonnenBatterie is an intelligent control centre that manages all the solar power in your household.

Built with your energy needs in mind

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 5 kWh to 15 kWh the sonnenBatterie will power a detached house or a multi-family house. The sonnenBatterie's energy capacity can be individually expanded in blocks of 2.5 kWh - should you ever feel the need to increase the power storage in your house.


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 45 kWh.
