Clean and affordable energy for everyone is the biggest challenge of our time. If we succeed to free our energy production from carbon-based emissions within the next ten years we will not only protect our environment but also our economical and political freedom.
Sonnen is introducing what it calls the sonnenBatterie eco, a battery unit about the size and dimensions of a small refrigerator (Figure 1). The eco is available in capacities of 4 kWh up to 16 kWh, and has an integrated smart inverter and control system allowing it to function as a home microgrid. Within that range, the eco units can be sized in 2-kWh steps.
