sonnenBatterie – Solar energy storage with lithium iron phosphate
The batteries are the basis of every storage system, which is why we focus on one thing with the sonnenBatterie: safety.
During their period of use, photovoltaic storage systems such as the sonnenBatterie are loaded and unloaded thousands of times over many years. Therefore, we have chosen a particularly reliable, sustainable and safe battery technology and only use lithium iron phosphate batteries (LiFePO4). They are considered to be more durable and safer than numerous other lithium-ion batteries that are used in smartphones, laptops or electric cars. Did you know already? Lithium iron phosphate is the only battery material that is even a natural compound and contains no toxic heavy metals.
