Background on sonnen – Company History
Founded by Christoph Ostermann and Torsten Stiefenhofer during 2010 in the German village Wildpoldsried. The intelligent energy storage system producer sonnen has the goal to emancipate the world from the reliance on fossil fuel, promoting the utilisation of decentralised clean energy. This has been achieved on a small scale by sonnen in Wildpoldsried, as the village runs on only renewable energy. Shell acquired 100% ownership of sonnen in 2019.
The hybrid 9.53 is the most recent sonnenBatterie to hit the market. The battery acts an intelligent storage system, it is similar in nature to the Tesla Powerwall 2 by the fact it automatically distributes power when necessary. In collaboration with solar panels, the sonnenBatterie hybrid 9.53 can potentially enable household energy independence.
Sonnen Manufactures Batteries in Australia
In November of 2018 sonnen opened their manufacturing plant in Elizabeth, South Australia. The sonnenBatterie hybrid 9.53 met the Australian Consumer Law and the Australian Made, Australian Grown (AMAG) Code of Practice. Meaning, that it is Certified Australian Made.

A fixed electricty bill from Sonnen
Sonnen offer their customers a unique solution which essentially provides a fixed monthly cost for the power called sonnenFlat. SonnenFlat is essentially a flat rate retail electricity plan package, available to those with a solar system size of at least 3kW and a sonnenBatterie of at least 4kWh in nominal capacity. Pricing for the different states from available providers can be found on sonnen’s website.
How does it work?
The sonnenBatterie hybrid 9.53 is a hybrid battery system, this means it integrates the components of energy storage into one system. The hybrid battery system contains a solar inverter, charger and battery. Solar energy storage systems can be AC or DC coupled, the hybrid 9.53 is DC coupled. This means it is connected at the grid, eliminating the need for an additional inverter. As the DC coupled hybrid 9.53 converts solar energy to AC electricity, which is used to power homes or be fed into the grid. And stores it as DC electricity in the battery.
The sonnenBatterie hybrid 9.53 can provide power in a blackout
The latest emergency power unit produced by sonnen is the sonnenProtect 2500. It is an additional unit that is used to complement the sonnenBatterie hybrid 9.53 system. It achieves this by serving as a single-phase power supply in the event of a power failure. With a nominal output of 2.5kW, the sonnenProtect 2500 provides an excellent backup power source for homes.
The Chemistry Behind a sonnenBatterie hybrid 9.53
The sonnenBatterie hybrid 9.53 is a rechargeable lithium iron battery, a newer variant within the lithium battery family. This lithium iron battery consists of lithium iron phosphate (LiFePO4), as the cathode material. And like other lithium batteries, its anodes are carbon. For an explanation of how batteries work in general, click here.
The lithium iron phosphate battery differs from the common lithium ion battery in a number of ways. Lithium iron phosphate batteries are safer due to the lithium phosphate holding a greater chemical and thermal stability. They are non-flammable meaning they last longer, as they can handle higher temperatures from a short-circuit or overcharge. This makes them a more economically sound battery choice, as the lithium iron phosphate has a longer life cycle compared to lithium ion. The sonnenBatterie hybrid 9.53 has an industry leading 10 year/10,000 cycle warranty.

Since 2008 our knowledge and sophisticated software has allowed over 180,000 Australian households and businesses to make a well-informed choice on their solar & battery installer.
South Australia, New South Wales, Victoria, and Australian Capital Territory all currently have a home battery scheme in place.
The South Australian Home Battery Scheme enables eligible South Australian residents to receive up to $4,000 per installed battery.
The New South Wales Home Battery Scheme offers an interest-free loan up to $9000 for eligible households looking to install a solar battery.
The Victorian Government under the Solar Homes Program provides to those eligible, a maximum discount of $4,174 off the battery sale price. The next release of battery rebates is on the 2nd of September 2020.
The Australian Capital Territory Government under the Next Generation Energy Storage program provides a rebate of $825 per kilowatt (kW). An average household with a 5 kW system would be eligible for approximately $4,000.
