sonnen: your questions answered
sonnen is the Australian arm of the German battery manufacturer, a clean-energy specialist since 2010. It provides the sonnenBatterie home storage system, a virtual power plant and sonnenFlat electricity plans across NSW, the ACT, Victoria, Queensland, South Australia, Tasmania and Western Australia.
The sonnenBatterie is a fully integrated, intelligent home storage system built around lithium iron phosphate (LiFePO4) modules with smart energy-management software. It stores excess solar so you can use it at night, and can join the sonnen virtual power plant (VPP) to help stabilise the grid. With sonnenProtect it keeps dedicated circuits powered during a blackout.
sonnen offers five sonnenFlat plans (City, Economy, Family, Autonomy and sonnenFlat 16) with generous annual household usage allowances matched to your solar PV size and battery capacity. There is no binding minimum contract and no exit fee — if you leave, your new retailer handles the cancellation.
For homes on the solar-panels program, sonnen pays around 4.0c per kWh exported in NSW, Queensland and South Australia. sonnenFlat plan members are also rewarded for contributing battery power to the broader sonnenCommunity through the VPP.
sonnen scores around 4.5/5 on ProductReview and 2.9/5 on TrustPilot. Reviewers praise cheap rates, easy sign-up and a quality battery; the most common complaints relate to customer support and battery faults. Experiences vary, so it pays to compare.
