Meets your energy needs whether you are a small or a big family. Every household has its own very specific energy needs. That’s why the sonnenBatterie was developed as a multi-stage storage system that can be adapted to the most diverse energy needs. With storage sizes ranging from 5 kWh to 15 kWh the sonnenBatterie will power a detached house or a multi-family house. The Sonnen Batterie’s energy capacity can be individually expanded in blocks of 2.5 kWh – should you ever feel the need to increase the power storage in your house.
Batteries are the basis of all energy storage systems
Over time they will be charged and discharged many thousands of times. For that reason the sonnenBatterie is based on the most reliable and sustainable battery technology available and exclusively uses lithium iron phosphate batteries (LiFePO4). These batteries offer a greater longevity and higher safety than most other lithium-ion batteries that are commonly used in smartphones, laptops or electric cars. Did you know: lithium iron phosphate is the only battery component that occurs naturally and does not contain any toxic heavy metals.
