German energy storage giant sonnen Group has revealed it expects to produce its first Australian-made residential sonnenBatterie within weeks, at the former Holden car factory in Elizabeth, South Australia.

Sonnen is supporting South Australia’s virtual power plant project, which is the linking of household solar panels and battery installations and then using the renewable energy stored to act as a source of power that can be controlled and sent into the grid as needed.

A German energy storage giant has chosen the former Holden car factory in Adelaide’s northern suburbs as the centre of its Australian operations.

Germany’s sonnen offers ‘free’ grid power deal to solar users

For the first time, sonnen is providing balancing power for the energy market by means of residential energy storage systems networked across the whole of Germany. The sonnen virtual battery, which is now online, is currently the largest of its kind that is able to compensate for fluctuations in the power grid. As a result, German households are now in a position to take over all the tasks of conventional power stations.

sonnen is pleased to announce the closing of its latest financing round of €60 million, led by Shell Ventures and significantly supported by all existing investors. The investmenr enables sonnen to expand its strategy of rapid international growth and to further enhance its pioneering position as the "utility of the future"

German energy storage systems manufacturer sonnen has introduced a radical new way of helping households cope with ever-rising power costs. The German battery storage maker will absorb all electricity charges, and instead charge a flat fee (of $30, $40 or $50 a month depending on the size of the dwelling and capacity of its rooftop solar array) for those households installing the company’s energy storage systems, saving the average home around $3,000 a year in power costs.
