Intelligent Energy Storage

The sonnen eco is a fully integrated energy storage system that stores excess solar electricity for use day, night, or even during an outage. The eco battery uses lithium ferrous phosphate (LFP) chemistry and comes in seven different sizes with usable capacities ranging from 5 kWh to 20 kWh (in 2.5 kWh steps). Compared with other types of batteries, LFPs, and more specifically sonnen are known for their safety and reliability, helping you power what’s most important in your life.
