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.

Blackout Insurance – SonnenBatterie Protect

Beat The Electricity Retailers

As well as supplying power in the evenings and early mornings, where Time of Use (ToU) metering applies you can take advantage of “rate arbitrage”. Store energy when it’s cheap and run your home off the sonnen battery when electricity prices are high – without any time-consuming or confusing fiddling.

German Quality – Market Leading Warranty

The  sonnenBatterie Eco is  guaranteed for 10,000 cycles or 10 years – providing you peace of mind that your battery system is built to last.

This is the best home energy storage warranty around – considerably more generous than competing products!

For example,  a 6kWh home battery system will have up to 16.43kWh of daily discharge capacity under warranty in a multiple cycles per day scenario.

(Please note: a stable Wi-Fi connection is required for this superb warranty coverage and Sonnen battery  warranty terms and conditions apply.)

Sonnen has been shipping these battery systems since 2008 – it’s a thoroughly tried and tested energy storage solution at a very affordable price.

User Friendly Monitoring – SonnenApp

Monitoring and controlling your energy usage and production is a snap with the sonnenApp. Using your mobile phone or tablet, you can view your system’s performance from anywhere there’s an internet connection. The sonnenAp will even show you the level of energy independence you’re achieving!


Sonnen battery – A Multi-Award Winner
