Germany’s sonnen wants to create a world in which everyone is able to meet their power requirements using cost-effective, decentralised and smart clean electricity systems that generate and store energy close to the point of consumption. The sonnen battery solution is the means to that end.

Introduction to sonnenBatterie Eco battery older version technology

In the first quarter of  2016 sonnen evolved into the largest home battery supplier in Europe, with more than 2,600 sonnenBatterie Eco units delivered and sold and 30,000+ systems shipped.

At the historic Holden Plant in Elizabeth, South Australia, sonnen manufactures the sonnenBatterie. In 2018, sonnen opened its Elizabeth facility, the third global manufacturer of our smart energy storage technology. Your battery is engineered with pride in Germany and made in Australia.

Since then, more than 100,000 units have been installed, and even after Shell bought the business at the beginning of 2019, sonnen has maintained its top spot in the German market.

Elegant, economical and powerful

The sonnenBatterie Eco was an elegant battery system. This was a tough battery, ideal for home energy storage applications in Australia.

sonnenBatterie Eco had many features and offered ample storage – from 4kWh – 16kWh in 2kWh incrementswithout needing to upgrade the built-in inverter.

sonnenBatterie Evo

Two 5kWh battery modules make up the 10kWh total usable capacity of the sonnenBatterie Evo. The cobalt-free and lithium iron phosphate cell technology, as well as the conditional 10-year or 10,000 charge cycle warranty, are further noteworthy features.

When you buy the battery, you’re already set to connect because it comes with everything you need, including an inverter.

Thanks to its modular approach, you can easily build on the system as you require by adding battery modules from sonnen.

sonnenFlat and sonnen Battery

In July 2017 sonnen announced that its would be offering sonnenFlat in Australia. sonnenFlat will give eligible homes (both new users and existing sonnenBatterie compatible solution owners) flat price electricity from just $59 a month, all day and night, even when the battery is flat and it’s the middle of the night or cloudy overhead! It’s another game changing shift from the global leader in home battery technology. It promises a quantum leap in the solar and electricity utilisation and valuation paradigm in Australia.

Make the most of solar with sonnen

Don’t export your high value solar electricity for a few cents per kilowatt-hour when you can store it and use it later on as needed. The sonnenBatterie will help you reap the maximum benefit from your rooftop solar panels and take more control over your mains grid energy use.

Sonnenbatterie energy savings

An All-In-One battery storage solution

The sonnenBatterie is a complete system; consisting of the best quality battery modules, an efficient inverter, an intelligent energy manager and the software to ensure it all runs smoothly and at peak performance. This is “plug and play” energy storage.

A very smart battery

The sonnenBatterie Evo features a self-learning algorithm that determines the best times to charge and supply.

Blackout Insurance – sonnenBatterie Protect

With the added sonnenProtect unit, the system can sense power outages in real-time and automatically switch over to battery power.  In a blackout, you could be the only house in the street with power.

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!

Backup solar power has been included, with a capacity of 5kW continuously and 7kW surge. In the event of a blackout, this gives power to run additional circuits in backup mode, covering more lighting and appliances in a home. An AC connected PV system can  “wakes up” by the sonnenBatterie Evo’s Black Start function even while the grid is down.

User friendly monitoring – sonnen app

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