If you are looking for a high performing battery then you will be looking at a Sonnen Battery. There are a lot of important questions to answer when deciding on the right solar battery option for your home. Our buying guide for the Sonnen Battery will help you with the process. Before you make a decision, first answer these questions:
If so, some State Government Rebates offer interest-free or low interest loans. Check out our article on Victorian solar home rebates for more information.
If there is no State Government Rebate you will need to spend at least $10,000 to $18,000. In South Australia, Victoria and Queensland you can get up to $6,000 off the cost of the Battery.
Do your numbers or have Solar Run do them for you. Solar batteries are a terrific long-term investment to save energy costs in the long run. With a premium battery like the Sonnen Flat, the upfront costs are high, so you need to be happy with the payback period.
It is important to know that installing the Battery outdoors will significantly reduce the lifespan of the Battery Cells. This can greatly impact your return on investment and your payback period, therefore the positioning of the battery in your home should be taken into consideration.
Installing a 10kWh and above Battery will keep your lighting circuits powered usually until the power returns.
A CEC Approval is an essential credential, as most State Government Rebates make this mandatory. Not choosing a CEC Approved Retailer will disqualify you from the Rebate.
If you have at least a 5kW solar panel system and a minimum of 5kW Sonnen Battery, you are eligible for the Sonnen Flat Energy Bundle. Customers on the bundled plan will only pay a flat fee starting from $30 per month. Whiles its not an unlimited product, the consumption allowance is still enough for the average house not to pay more then the monthly cap. The table below compares the available Sonnen Flat Energy Bundles.
Sonnen is regarded as one of the top Energy Storage Manufacturers in the world and were recently acquired by Shell. They are renowned for their quality product engineering and market-leading warranties. Sonnen believes that it is already possible to economically produce clean energy at home today. What started as an idealistic idea, Sonnen has become one of the biggest producers of intelligent energy storage systems. The headquarters of Sonnen is in Wildpoldsried. A Bavarian village that is already running on 100% renewable and clean energy. Sonnen announced in 2018 that it will be opening an assembly facility in the former Holden factory located in Adelaide.
Sonnen Battery’s are widely installed in South Australia. They also offer a Virtual Power Plant option called sonnenFlat. While they are commonly written as Sonnen, they themselves prefer to not to capitalise the S (sonnen).

Yes. All of their batteries are clean energy council approved. Widely sold in South Australia Sonnen provides market leading batteries. Here in Australia we get very cold temperatures in Winter. In summer we get very hot temperatures. Based on our review we recommended that solar batteries are keep away from direct sun. Sonnen batteries have a wide range of operating temperatures.
Yes. The Sonnen Battery is AC coupled and is compatible with most CEC Approved Solar Inverters. This is only important when adding Solar Battery Storage to an existing system.

This will make the installation very neat and tidy.
The price of a Sonnen Battery in South Australia, Victoria and Queensland is reduced thanks to additional State Government Rebates. The rebate can cut the costs of the battery storage in half. This rebate therefore makes the Sonnen Battery significantly more affordable. For other states, the cost of a full price Sonnen Battery could be up to $18,000 installed. Sonnen prices are more expensive than some other leading Solar Battery Providers. What you get for the extra cost is a powerful and reliable German-Engineered Battery Storage System.
Yes, based on our Sonnen Battery Review. In some State Government Rebate Schemes its mandatory. The South Australia Home Battery Scheme requires all approved products to be VPP ready. Sonnen batteries are a great choice if you are considering signing up to a VPP (Virtual Power Plant). A VPP allows many solar systems to act together as a power plant. Collectively a VPP can then store power when it is cheap and sell it when the price is higher. The bigger the VPP the bigger the buying power. VPPs are not yet common but being “VPP ready” is an important consideration. Sonnen runs their own VPP system called sonnenFlat (available in South Australia).

Yes, but its usually an extra cost. It is available as an added extra from the manufacturer but it isn’t a requirement as black outs across major cities in Australia are few and fair between. If you do require battery back up, its worth working out how long you need battery back up for vs how long will the battery storage system will keep you running for.
