MRACK System

Liquid-cooled Power Conversion for AI and Grid Applications

The EPC Power MRACK System is a liquid-cooled power conversion platform engineered for utility-scale energy storage and AI data center applications. Built with silicon carbide technology, the modular system delivers industry-leading efficiency and Agile Grid Forming™ capabilities in a compact, scalable, high-power-density design.

Reliability by Design

Manufactured in the USA and designed for reliability and operational simplicity, MRACK features built-in redundancy, predictive analytics, and remote diagnostics, with seamless integration to next-generation battery technologies for both on-grid and off-grid applications. Systems can hold up to 14 modules in parallel, and—like the air-cooled M System—MRACK is available with Agile Grid Forming™ technology to support AI load smoothing.

Individual MRACK inverters can also be integrated into BESS enclosures for customized battery storage solutions that need internal power conversion.
