AC Coupled Sonnen website

 

We are certified and accredited Sonnen Batterie installers. Germany's leading battery storage company now manufacturing out of South Australia's former Holden site. In our opinion the best AC coupled battery system available. With Lithium battery cells manufacturerd by the original invertor Sony in Japan, and smart German design, you can be sure of absolute quality in this system. With identical cells cycling in tests for over 18 years and still performing better than the 10 year warranty, this world class product manufactured here in SA will take some beating.

This system is adaptable so you can start at the maximum subsidy 10kWh unit and can upgraded to a massive 16kWh if you require.

Another key advantage is the Sonnen Flat tariff, an industry leading retail electricity tariff where you can pay nothing for power! Please contact us for more information.
