Large-scale battery storage systems for commercial, domestic, emergency and off-grid applications

Large-scale battery storage systems enable storage capacity to be sold at fixed prices, relieve pressure on the electricity grid during peak periods and reduce the need for investment in grid expansion. Large-scale battery storage systems complement this function by integrating renewable energy – for example, in combination with photovoltaic systems – sustainably reducing electricity costs and providing a reliable emergency power solution for TRAS120 systems and other critical infrastructure.

Energy center "Wattmeister"

- the modular high-end solution

The “Wattmeister” energy center is more than just a large-scale battery storage system – it is intelligent storage technology for the energy of tomorrow. Designed as a scalable, grid-compatible, and fully integrable system solution for self-generation, load management, and emergency power, it was specifically developed for biogas plants, agricultural operations, municipalities, and commercial customers. Its intelligent control system, flexible design and wide range of functions ensure maximum independence from the electricity market – economical, efficient and future-proof.

Technical highlights in detail

The Wattmeister systems are available as indoor and outdoor solutions – with optimized space requirements, sophisticated temperature management, double air conditioning system and optional emergency power generator. They support electricity price optimization (exchange price data), time shift for CHP units, integration of generators and consumers as well as uninterruptible emergency power switching. Depending on the model, the output ranges from 45 kW to 180 kW, with storage capacities of up to 4,000 kWh per container. Even demanding grid connections can be realized thanks to extensive support in approval, design and metering concepts.
