Juwi Office Building

Secure Power Supply with SUNNY BACKUP SET Juwi sets new standards:

the solar engineering company built an office building with the highest energy efficiency in the world in Wörrstadt/Germany. The office complex was constructed of wood and has a surface of 8,500 m² providing space for approx. 300 employees. The entire energy supply is covered by renewable energy sources.

Doing this, juwi relies on the technology of SMA: the company headquarters is equipped with a solar power plant that reliably protects important loads from power outages with the Sunny Backup Set. For this, the SMA Sunny Backup System charges the batteries and switches automatically to Backup operation, if necessary. Nine Sunny Backup inverters, with 5 kW each, supply PCs, telecommunication, emergency lighting and fire sprinkling system with energy – even in the event of a grid failure.
