Make your business independent—with commercial storage systems for large consumers

A commercial storage system—also known as industrial storage or large-scale storage—stores PV electricity or grid electricity and makes it available at any time. Perfect for smoothing out peak loads, maximizing self-consumption, and controlling energy costs.

Whether for industrial buildings, agricultural businesses, or hotels, our scalable storage solutions (30 kWh to 200 kWh or more) adapt to your consumption for maximum cost-effectiveness and self-sufficiency. Large consumers benefit in particular from predictable costs and maximum grid independence.
