Sonnenbatterie is a German manufacturer of energy storage devices with a focus on electricity self-sufficiency. The company, whose name means ‘solar battery’ in German, offers products that not only store energy, but also allow a high degree of flexibility and feedback as to how electricity from all sources–batteries, solar panels, the grid, wind power, or others–is and should be utilised throughout the day.
On top of these capabilities and functions–and setting them apart from many other energy management devices in in the field–Sonnenbatterie units are able to incorporate weather forecasts in order to predict likely system energy yield against likely consumption, ensuring that energy is used in a way that optimises savings.

Sonnenbatterie: Points of difference
–One of the world’s first fully integrated lithium (LiFePO4) storage systems, introduced in 2011 after pilot projects in 2010, Sonnenbatterie’s products are now in their 4th generation
–Making it easy for homes to reach 80% energy self-sufficiency by intelligently switching between solar panels, mains electricity, batteries and other types of generators, leading to energy bill savings of up to 75%
–Intuitive operation with smartphone app & web interface, making it easy to monitor system performance and prioritise energy sources for optimum savings
–Easy integration with more than just solar PV. Other power sources that can be plugged in include wind power, combined heat and power (CHP) generators, and of course, mains electricity

Hi, I have 38 solar panels on my roof, presently feeding back into the grid, and supported by the NSW State subsidy, which will run out in
December, 2016. I would be interested to hear about your battery storage system, as I will have to change to another system in January 2017. Will you send me a brochure or details, and where to obtain this system by the end of this year, costs, etc. and what your system is capable of doing for my solar output. Many thanks, Loren Noble.

Hi,
Any idea if they have launched in Australia yet?
Thanks,
Adam
Hi Adam,
Yes, their batteries have been available here in Aus for a few years now (in small quantities). They’ve even mulled setting up a production factory here.

Hi
Have Sonnenbatterie gotten any further in introducing their product to the Australian market?
Hi Shane,
They’ve re-branded themselves as Sonnen and will apparently be introducing their products here, probably within the year.
Is there any update on the availability of these systems in Au yet
And if so at what cost?
Hi Ben,
We understand that Sonnenbatterie are now looking to enter the Australian market, but their products are not available here yet.
hello, i am wondering if these systems are available in australia yet or if you have any time frame for this to happen
thank you, fiona
Hi Fiona,
As far as we are aware, Sonnenbatterie was investigating entry into the Australian market but its products are not yet offered here.
Hi,
Do you sell battery storage systems in Australia? Do you have any pricing available on the Eco13.5 system. I think this system would best suit my needs.
Hi Paul,
Thanks for the comment. Sonnenbatterie’s products are not yet available in Australia, but we can let you know when they are.
