Eos energy storage system

Suitable for commercial, industrial, and utility-scale projects, both behind- or front-of-the-meter, it’s a truly “plug-and-power” solution with integrated battery modules, Battery Management System (BMS), and enclosure that can be installed, run, and maintained at low cost and high speed. An Eos storage system, coupled with solar panels or a wind turbine, can turn any building—even a high-rise in a dense urban center—into a mini power plant that supplies its own energy when the grid is down, or delivers excess energy to the grid when demand is high.

What are the building blocks of EOS energy storage systems?

Power that stacks up. Z3 battery modules are the building blocks of all of our ingenious energy storage systems. Our standard Z3 strings are racked in a variety of configurations to form our Eos Cube, Eos Hangar, and Eos Stack solutions. Fully recyclable at the end of their usable life, Eos batteries are a truly sustainable solution.

What does Eos do?

Eos is accelerating the shift to clean energy with positively ingenious solutions that transform how the world stores power. © 2025 Eos Energy Enterprises All rights reserved. Eos is accelerating the shift to clean energy with positively ingenious solutions that transform how the world stores power.

What is Eos storage & how does it work?

Eos storage systems plus Solar and Wind reliably solve the intermittency of green sources—while helping you gain community support. Non-wired Eos storage ensures critical supply during outages and congestion on today’s networks—and the transition to tomorrow’s infrastructure.

What is the EOS cube?

A containerized BESS solution that fits in almost any site and weathers almost any climate. We designed the Eos Cube to bring affordable and reliable energy storage to even the harshest, remotest locations.

What is Eos BMS?

Protecting health and performance. The Eos BMS is an integrated electronics package that provides real-time operational telemetry and status, automatic protections and, in conjunction with the site controller, executes use cases and controls the Eos Cube systems, all to minimize battery stress and wear while maximizing output energy capacity.

What makes EOS a good battery?

Safe, simple, durable, flexible, and available, our commercially-proven, U.S.-manufactured battery technology overcomes the limitations of conventional lithium-ion in 3- to 12- hour intraday applications. It’s how, at Eos, we’re putting American ingenuity to work every day to create a positive future for everyone.
