Home batteries

A free home battery was offered to South Australian households rebuilding after the 2019–20 bushfires, under an arrangement offered by the South Australian Government and local battery manufacturer, sonnen.

Under the offer, bushfire-affected households could receive a sonnen battery as part of the rebuilding of their property.

Registrations of interest for this offer closed on 31 December 2020. The program team is now helping with the deployment of batteries on  households.

Information for households that accepted the offer is provided below. For any other enquiries, please contact the Home Batteries call centre on (08) 8226 7595 or email bushfirebatteries@sa.gov.au.

What happens if I accepted the offer but the battery is no longer part of my rebuilding plans?

If for whatever reason you no longer require the battery, all we ask is that you let us know your decision as soon as practical so we can remove you from our system and deactivate the Unique Identifier Code provided to you on receipt of your acceptance. You can do this by contacting the Home Batteries call centre on (08) 8226 7595 or emailing bushfirebatteries@sa.gov.au

If I accepted the offer, how long do I have to install the battery?

You have until 31 December 2021 to have your battery installed. After this date, consideration for an extension will only be given on a case-by-case basis.

What size of solar system is required to pair with the battery?

Households are encouraged to seek advice from a certified sonnen installer about what size system would suit their needs. A list of installers was sent to all eligible households together with the letter of offer.

Can the batteries operate in the event of an outage?

sonnen home energy systems do have backup functionality at an additional cost to the household. Eligible households are encouraged to discuss this with a certified sonnen installer before the system is installed.

Does the battery need to be installed by a certified sonnen installer?

A certified sonnen installer must install the home energy system – this is a sonnen requirement. A list of providers was provided along with the offer.

If I accepted the offer but decide not to rebuild and want to live outside the bushfire-affected region, am I still eligible for a battery?

No. The battery must be installed on the bushfire-affected property. Please contact the Home Batteries call centre on (08) 8226 7595 or email bushfirebatteries@sa.gov.au to let us know your decision as soon as practical so we can remove you from our system and deactivate the Unique Identifier Code provided to you on receipt of your acceptance.

Can I install the battery on a structure that wasn’t destroyed or damaged by the bushfire, such as a nearby shed?

Yes. Eligible households can determine the location of their battery, providing it is on the same location (NMI) of the impacted primary residence.

If I sell my property before the battery is issued and installed, will the new owner be eligible for the battery?

No. The offer is only available to the original recipient. Please contact the Home Batteries call centre on (08) 8226 7595 or email bushfirebatteries@sa.gov.au to let us know your decision as soon as practical so we can remove you from our system and deactivate the Unique Identifier Code provided to you on receipt of their acceptance.

Are batteries safe in the event of another bushfire?

Yes. sonnen battery modules have been tested and certified to IEC 62619 and UL 1973 standards and are deemed as not posing a fire hazard under AS/NZS 5139:2019. The sonnen LFP2 modules do not ‘out-gas’ in normal operation and will shut down in cases of extreme heat. In the extreme event of an actual fire this will not cause any exacerbation of the situation.
