9News: sonnenBatterie to take on the likes of Tesla

Make the Most Of Solar with the sonnenBatterie

Don’t export your high-value solar electricity for a few cents per kilowatt-hour when you can store it and use it later on as needed. The sonnenBatterie will help you reap the maximum benefit from your rooftop solar panels and take more control over your mains grid energy use.

An All-In-One Battery Storage Solution

The sonnenBatterie is a complete system; consisting of the best quality battery modules, an efficient inverter, an intelligent energy manager and
the software to ensure it all runs smoothly and at peak performance.
This is “plug and play” energy storage.

A Very Smart Battery

Germany’s sonnenBatterie is the world’s largest home battery storage provider, not only helps maximise the value of your solar power and provides some of the best warranties in the industry, but also provides access to smart features, including self-learning algorithms that help determine the best time to charge and discharge your battery, making sonnenFlat a reality today.

“If you have a sonnenBatterie you will probably need it for charging and discharging around 6-7 hours a day. That leaves up to 18 hours that your battery, (which you have already paid for), charged for other services.
sonnenBatterie has a very high cycle life so we have enough charging cycles available to participate in the electricity wholesale market and grid stabilisation

sonnenFlat Australia

In July 2017 Sonnen announced that it would be offering sonnenFlat in Australia.  SonnenFlat packages will give eligible homes (both new users and existing sonnenBatterie compatible solution owners) flat price electricity from just $30 a month, all day and night, even when the battery is flat and it’s the middle of the night or cloudy overhead! It’s another game-changing shift from the global leader in home battery technology. It promises a quantum leap in the solar and electricity utilization and valuation paradigm in Australia.

Eligible sonnenBatterie owners who sign up to sonnenFlat will receive access to grid electricity based on the size of their battery system, the total amount of solar power the customer has installed and their expected home energy consumption.

In return for giving a customer access to sonnenFlat electricity packages, Sonnen will occasionally be able to draw electricity stored in a network of Sonnen batteries in a virtual power plant scenario to help balance the energy grid during times of high usage demand, helping improve Australia in making the shift to distributed generation and alleviate grid bottlenecks when is most needed.

Benefits don’t end here; SonnenFlat packages will not only cover a large portion of customers’ energy consumption by replacing with a low monthly fee but will eliminate daily connection charges helping have you bill under complete control.
