Volt Harbor, an energy storage technology company, has closed a $2 million seed financing round led by MFV Partners to launch and commercialize its patented medium-access-control battery energy storage system technology.

The company said the financing will support its transition from pilot deployment to commercial deployment. Volt Harbor said the modular, software-defined energy storage platform is designed to address data center power demand and aging utility infrastructure.

“Energy storage and power electronics have always been treated as separate boxes. We’ve integrated them, along with on-board computing, into a single, software-defined product class,” said Al-Thaddeus Avestruz, President, CEO, and co-founder of Volt Harbor, and a former professor at the University of Michigan, where the company licensed its core technology. “That combination is where the real performance, reliability, and cost advantages come from, and what data center and grid operators are looking for as they look to access more reliable power on a faster time scale.”

Volt Harbor’s medium-access-control system uses software to coordinate power flow among battery modules from different manufacturers and chemistries in real time.

Built on six University of Michigan patents, the platform integrates battery storage, power electronics, and computing. It can utilize both new battery cells for data centers and second-life EV batteries for commercial, industrial, and utility-scale applications.

The system is designed to buffer high-power charging events for electric vehicles that exceed local capacity. Volt Harbor said the system will also provide demand response, peak shaving, and backup support.

VC funding raised by Energy Storage companies in Q1 2026 increased 9% YoY, with $1.2 billion in 26 deals compared to $1.1 billion in 18 deals in Q1 2025, and a 44% increase in deal count, according to Mercom’s Q1 2026 Funding and M&A for Energy Storage report.

In December 2025, FION Energy, a Berlin-based company that installs and operates smart battery systems for industrial companies, closed a €1.4 million (~$1.6 million) pre-seed funding round. The funding round was led by HTGF and Norrsken Evolve, with participation from experienced business angels.
