Sonnen, headquartered in Germany, is the leading manufacturer of smart energy storage systems.

Sonnen batterie is the high-tech storage system that regulates energy usage in the household. If you install the solar PV system with Sonnen batterie, you can generate your own clean energy to meet your power requirements without worrying about hikes in electricity prices.

Sonnen opened its manufacturing plant in South Australia in November 2018. Sonnen has successfully delivered thousands of sonnenBatterie hybrid 9.53 Certifed Australian Made home battery storage systems throughout Australia.

You know in most households, the maximum consumption of electricity is in the morning and in the evening but the solar PV system generates maximum power during the day time. Here, Sonnen batterie comes to play. It stores the energy produced in the day time. This stored energy is then used by the household in the evening when the solar PV system produces very little energy. Hence, you are using clean energy throughout the day.

It comes with 10-year full warranty or 10,000 charging cycles.


It is the safest lithium battery available today because lithium iron phosphate (LiFePO4)) batteries are used in making of this intelligent battery storage system. Note: lithium iron phosphate is the only naturally occurring battery component that does not contain toxic heavy metals.

Expandable Capacity

This modular battery system can be customized as per your household needs and you can also add extra storage modules in the future.

Ideal for both small or large family

The multi-stage storage system in Sonnen batterie is specially designed keeping in mind the diverse energy needs of different households. The sonnen battery will power a detached house or a large family house with energy storage capacity ranging from 5 kWh to 15 kWh (further expandable in blocks of 2.5 kWh) .

The complete system
-High quality and long-lasting

The sonnen battery has all components in one box – ready for connection. Inside the high-quality Sonnen battery case, in addition to extremely durable battery modules, you will also find an inverter, an intelligent energy manager, measurement technology, and software for smooth operation.

Multiple Sonnen batteries for energy independence

Need more energy storage capacity for residential or commercial buildings? Don’t worry! Sonnen batterie can be setup in a ‘cluster’ (3x15kWh), thereby storing a total of 45 kWh of energy (maximum capacity).

Recent Awards

In December 2019, Sonnen received Australia’s “Research and Development Investment” award for establishing an energy storage solutions manufacturing plant in South Australia.

For the third time in a row, Sonnen received EuPD Research “Top Brand PV Storage” in Australia in March 2019.
