Tesvolt Power Safe battery storage solution

Tesvolt and Denios have partnered to present the Power Safe, an all-in-one solution that combines a battery storage system and fire protection. The Power Safe product line also meets the safety requirements in commercial and industrial settings; eg, in operations located in water conservation areas or regions that are at a risk of forest fires, or as required by some insurers. Products in this line feature cases offering F90 fire resistance rating and are available in various sizes, from small-scale 80 kWh solutions to large energy storage systems with several megawatt hours.

In the Power Safe product line, storage systems come in a spatial system with dual-frame construction classified as REI 90 or REI 120 fire protection. It is designed to withstand fire, either internal or external, for at least 90 min, fulfilling the standards for safety certification required by approval authorities and reducing complex approval processes. This safety certification also allows the system to be installed without a minimum clearance between it and adjacent buildings. Moreover, Denios offers round-the-clock remote monitoring and will alert the operator immediately in the event of a problem with the system. An aerosol-based extinguishing system is also available for the spatial system.

The storage systems feature prismatic battery cells; the battery management system also monitors the voltage of each individual cell. This means the whole system is subject to constant plausibility monitoring. If the normalised range is exceeded, the system automatically switches to a safe state. Power Safe spatial systems with fire protection come with European Technical Assessment (ETA) and associated CE labelling. This offers enhanced planning and legal security for country-specific approval processes.
