Sonnen Batterie Evo price and what it is
The Sonnen Batterie Evo is an all-in-one home battery with sonnen’s own inverter built in: 10 kWh usable (11 kWh nominal), lithium iron phosphate cells, made in Germany. The kit is $9,680 including GST, for the equipment only; installation is quoted separately after a site check. Helcro Electrical is a Sonnen Certified Partner and installs home batteries across Melbourne’s South East.
Who the Sonnen Batterie Evo suits
- Homes that already have solar: it is AC-coupled, and sonnen says it can be added to an existing solar system without changing the panels or the solar inverter.
- Single-phase homes: it connects to a single-phase supply.
- Backup for the essentials: in a blackout it can power the circuits wired as essential loads.
- Indoors or outdoors: it is IP56 rated, but it can’t go in direct sunlight.

What affects the installed price
We price the installation after a site check, because a few things change the work:
- Backup wiring: the Evo only powers the circuits wired as essential loads, and only if the installer connects the backup function. We include the backup wiring you want in the quote.
- Your switchboard: if it needs an upgrade, a home switchboard upgrade is typically $1,250 to $2,500.
- Internet: the Evo connects by Ethernet, and sonnen needs it online for monitoring and for its warranty (the battery still runs without it).
- Where it goes: a spot out of direct sun that meets the battery installation standard.
sonnen’s warranty requires a sonnen-certified installer. On top of it, our workmanship warranty on battery installations is 10 years, and it carries over to a new owner if you tell us in writing. Your written quote follows a $50 site assessment (including GST).
The federal battery discount
The federal Cheaper Home Batteries Program is worth about $250 to $270 per usable kWh on the first 14 kWh as at November 2026, and it is usually taken off the price by your installer when you buy. It steps down on 1 January 2027. Eligibility depends on the exact model and set-up; we check it before we quote. There is no separate Victorian battery rebate. The full rules are in our battery rebate guide, and our solar battery comparison sets the Sonnen Batterie Evo against the other batteries we install.
Sonnen Batterie Evo questions
How much does a Sonnen battery cost?
The Sonnen Batterie Evo kit is $9,680, including GST, for the equipment only. Installation is quoted after a site check, and the federal discount comes off for an eligible set-up.
Does the Sonnen Batterie Evo work in a blackout?
Yes, for the circuits wired as essential loads, if the backup function is connected. It switches over automatically, has a Black Start button, and sonnen says it can recharge from a single-phase solar system of up to 6 kW during a blackout.
Can I add a Sonnen Batterie Evo to my existing solar?
sonnen says yes: it is AC-coupled, so your panels and solar inverter don’t have to change. We check your system at the site visit.
Where are sonnen batteries made?
sonnen lists Germany as the country of manufacture for the Evo.
