Solar Batteries

About Sonnen

Sonnen was founded in 2010 and was one of the first suppliers of lithium iron solar batteries for home use in Germany. Over the years, Sonnen’s popularity in Australia has grown due to its aesthetically pleasing all-in-one design and reliability. In contrast to many other battery systems on the market, the sonnenBatterie’s perfectly attuned components are built into one single high-quality cabinet to ensure longevity and quality with a small footprint. A sonnenBatterie installation is without doubt one of the ‘neatest’ and least visually intrusive.

The sonnenBatterie can be easily connected to any solar power system – new or existing. They are a beautifully simple add-on to help homeowners maximise the utilization of their solar power production.

The sonnenBatterie contains Lithium Iron Phosphate (LFP or LiFePO4) cells for their stability, durability, performance, and environmental friendliness. LiFePO4 is widely acknowledged as the safest lithium battery storage chemistry as it is very resistant to overheating and ‘thermal runaway’. Thermal runaway is where there is an uncontrollable rise in temperature and the batteries catch on fire. LiFePO4 batteries would need to get to temperatures in the vicinity of 480 degrees to suffer thermal runaway, which is very unlikely.
