arXiv:2610.32425v1 Announce Type: new Abstract: About PowerNexa PowerNexa is the project name for a start- up initiative driven by Marco Liserre and Steffan Hansen with the ambition to develop the next generation power grid interface. Battery integration and DC loads Ongoing electrification is fundamentally changing how electrical energy is produced and consumed. DC loads are becoming an integral part of the infrastructure while battery integration is increasingly needed to manage peak demand and address grid capacity constraints. The next generation grid interface PowerNexa aims to combine a fully controllable Medium Voltage grid interface with native battery integration and multiple DC voltage levels, based on an architecture designed for high efficiency, modularity and redundancy.
