Volt Harbor, Inc. is an Ann Arbor, Michigan deep-technology company building modular, software-defined battery energy storage systems under its patented MAC-BESS platform.
As of its 2026-05-28 public launch, the company had closed a $2 million seed round led by MFV Partners and was deploying a system on the DTE grid as a DTE Energy Emerging Technology Fund recipient.
Volt Harbor addresses data center power demand and aging utility grid infrastructure, the two markets its MAC-BESS platform is designed to serve.
The platform's battery-agnostic, software-defined design lets it serve high-reliability data centers with first-life cells and commercial, industrial, and utility-scale customers with second-life electric-vehicle batteries.
Volt Harbor's competitive advantage centers on its patented MAC-BESS platform, which integrates battery storage, advanced power electronics, and on-board computing into a single modular system.
The platform is battery-agnostic across manufacturers and chemistries, and its core technology is built on six patents licensed from the University of Michigan.
