The Smart Energy Router (SER) enables interconnection and power flow control in distribution grids. Based on Solid-State Transformer (SST) technology, it actively adapts to grid changes and modernizes energy infrastructure.
Overcoming Key Challenges
Industries and businesses face challenges in electrification, including:
- Hybridizing power grids to integrate charging stations, batteries, and renewables
- Providing grid-support services (reactive power, MV/LVDC connectivity, voltage/frequency control)
- Developing DC microgrids for stationary and e-mobility applications
Fraunhofer ISIT develops cutting-edge solutions for fast-charging stations and reliable megawatt-scale power supply using our project expertise.
Technological Innovation
The Smart Energy Router includes a configurable DC/DC power converter of 40 kW, acting as an energy hub for multiple assets up to the multi-MW scale. This strengthens resilient power supply for microgrids, charging infrastructure, and industrial sites—without costly grid expansion.
Its compact, efficient, and reliable design ensures safe operation, thanks to integrated electrical isolation.
