Storage pioneer from Germany
Over 15 years of experience with smarter energy:
sonnen is one of the pioneers in intelligent energy storage. Since 2010, we have been developing groundbreaking technologies in Germany and quickly demonstrated that battery storage can do more than just store energy: it can connect energy, open markets, and make supply cleaner, more flexible, and more resilient.
Today, we bring this experience to businesses: with solutions that combine storage, energy management, and service into one system.
From Home Storage to System Solution
What began over 15 years ago as battery storage for private households is today a system approach that has been creating added value in commercial and industrial sectors for years.
sonnenPro bundles this experience into solutions that make energy more cost-effective: reducing peak loads, optimizing self-consumption, integrating charging infrastructure, and managing operations more predictably – with intelligent control and reliable operation.
Energy only truly delivers value when integrated
sonnen has always thought of energy as a system: In the private sector, we connect storage, apps, electricity tariffs, and the sonnenVPP to form an intelligent energy system. With sonnenPro, we bring this experience to the commercial and industrial sectors – with storage solutions, energy management, and services for businesses.
