Sonnen’s journey started in 2010 in a small town in Southern Germany and was driven by the desire to make clean and affordable energy available to anyone. Today, the company is a global leader in energy storage solutions with offices in Germany, Italy, Great Britain, the US and Australia.
Knowing that every household has unique energy needs, Sonnen developed the sonnenBatterie as a multi-stage storage system that can be adapted to meet the most diverse energy requirements.
sonnenBatterie Solar Batteries
The sonnenBatterie is available in storage sizes ranging from 5kWh to 15kWH and designed to make your home sustainable and independent. It’s a complete system that’s ready for connection and comes with an inverter, intelligent energy manager, measurement technology and the software to operate it all smoothly.
There are three solutions for homeowners, including the sonnenBatterie 10, the sonnenBatterie eco and the sonnenBatterie hybrid, all of which use lithium iron phosphate batteries. The more powerful sonnenBatterie pro is suitable for commercial buildings with large solar arrays.
Sonnen says the combination of a sonnenBatterie and a PV system will allow you to cover around 75% of your yearly energy requirement with self-produced and clean energy. What’s more, the sonnenBatterie’s energy capacity can be expanded in blocks of 2.5kWh if you need to increase your home’s power storage.
