M System

Innovative Engineering

One platform engineered for maximum performance, mission-critical reliability, and the flexibility to power data centers and BESS.

One Platform.
Every Application.

The EPC Power M System is the digital power processor built for the most demanding power environments on earth. High-density SiC modular architecture configures to any footprint, at any scale. Availability >99.9%. Manufactured in the USA.

For data centers, proprietary Agile Grid Forming™ technology absorbs load volatility in real time, protecting generators, stabilizing the grid, and keeping AI workloads running without interruption.

For BESS grid solutions, a 500kW block size enables precise inverter-to-battery matching across all battery types, while the M10 flexible bus ensures safe connection to any battery container configuration.
