Built in Germany, the sonnenBatterie is an intelligent storage system designed to store excess solar electricity and automatically adapt the electricity usage in your household to maximise energy independence.
Sonnen solar batteries are built using lithium iron phosphate (LiFePO4) batteries. Commonly used in smartphones, laptops and electric cars, lithium iron phosphate batteries are dependable, safe and proven to perform.
| Battery | Dimension (W x H x D) | Weight |
| 2kWh to 8kWh | 66 x 130 x 36cm | 71kg to 162kg |
| 10kWh to 16kWh | 66 x 180 x 36mm | 187kg to 273kg |
