Introducing the Sonnen Battery System

Intelligent, Long-lasting and Economical – The Sonnen Battery

The Sonnen Battery is a high-tech storage system.The combination of a PV system and a Sonnen Battery will allow you to cover about 80% of your yearly energy requirement with self-produced and clean energy. Since your energy is being generated on your roof and not by some anonymous energy provider you are more independent than before. So take your energy future into your own hands and reduce your energy costs to a minimum. The decision for a Sonnen Battery is also a decision for the highest standards in safety and quality that “Made in Germany” stands for. When you purchase a Sonnen Battery system you are buying the World’s most popular and proven solar storage battery system. Using German technology and now being manufactured in Australia, over its lifetime this battery provides double the kilowatt-hours of its competitors. You may also be eligible to cap your electricity costs by joining Sonnen Flat. Your electricity will be covered by Sonnen up to a realistic kWh amount for a monthly fee a bit like with a mobile phone plan.  It removes the retailer as ‘middle-man’ and could save you thousands of dollars.

About the Sonnen Battery System:

The battery is the heart of the storage system, they will charge and discharge many thousands of times over the life of the system.  It is important to have the most reliable and sustainable battery technology. The Sonnen Battery Eco 8 system offers just this, It exclusively uses lithium iron phosphate batteries (LiFePO4). These batteries last longer and have a higher safety performance than most other lithium-ion batteries that are used in laptops, smartphones and electric cars. Lithium iron phosphate occurs naturally and does not contain any toxic heavy metals

Sonnen Flat is a World first and will definitely shake-up the Australian market. Choosing Sonnen Flat as your electricity distributor effectively caps your electricity expenses at $42 to $62/month depending on consumption.  It makes you part of a virtual solar power plant which looking into the future could be the means of selling solar power to people who don’t have solar systems but want reliable, cheaper electricity than the grid will be able to provide. This is already happening in Europe. Even if you don’t go for the Sonnen Flat deal, you are purchasing a solar battery that can cycle three times a day.  As a household you will be capable of producing a lot of solar generated electricity for your own use or to send to the grid.

The Solar Battery that Learns How You Live!

The sonnen battery will store the surplus energy generated by your solar power system when you don’t need it. The stored energy from the daytime is then at your disposal in the evening and during the night. However, the Sonnen is much more than just a battery, it’s an intelligent storage system that automatically adjusts the energy use so that most of your self-generated solar energy stays in your household.


Minimal energy production, high energy needs. At sunrise the solar panels start to produce energy, though not enough to cover the morning energy needs. The Sonnen will bridge the gap with the stored energy from the previous day.


During the day solar panels’ energy generation is at its peak. If nobody is home the energy consumption is very low so that most of the generated energy is stored in the Sonnen batteries.


The highest daily energy consumption is usually in the evening when the solar panels produce little or no energy. The Sonnen system will cover the energy produced in the daytime.

Peak and off-Peak prices

The Sonnen enables you to store energy when it is cheap and run your home off the battery when rates go up. However, for an average household you should no longer have to worry about different price rates because you will be consuming your own power and the Sonnen Flat deal provides for any electricity you need from the grid above your solar output.
