Eos Stack
Customization comes standard.
Every Eos Stack is made up of a single racking module holding individual Eos Z3™ battery modules. Multi-Stack installations can be designed with all racks centralized within a space or spread along walls—single file or in double-height configurations, depending on available space—providing ample flexibility to support varying project sizes and interior layouts.
Turning big buildings into powerhouses.
Simple, safe, durable, flexible. In every aspect of our Eos Stack, we’ve intentionally considered how both commercial and residential city buildings can integrate energy storage into their existing footprint and manage the installation with their existing teams. So that even our largest metropolitan areas can easily participate in creating a cleaner, less costly energy infrastructure.
A storage room for energy storage.
Eos Stack installations require minimal construction work. Just a simple foundation under each rack for spill containment, space for our control cabinets—each one can support up to two Stacks—and basic ventilation fans are all that’s needed to turn any indoor space into a fully-functioning battery room. And the open racking of our Stacks makes ongoing maintenance a breeze.
Safely site even in midtown NYC.
Our Eos Z3 battery modules are made and filled with non-flammable, non-corrosive materials that are less harmful than common household cleaning products. They don’t need noisy HVAC to stay cool. And they can be shipped and installed at zero charge. Which means our Stack systems can be safely transported to just about any location without a hazmat classification, sited in the building basements of even the most densely populated cities in the world, and handled and operated with basic workplace safety procedures and equipment.
The workhorse of energy storage.
Like the Eos Z3 battery modules they house, our Stack system has no delicate internal or external moving parts like HVAC or flow pumps that will degrade from continuous, daily wear and tear. Lasting at least 20 years and retaining a full 88% of the rated capacity, today’s Stacks will still be powering away well into the 2040s, no matter what temperature abuse or operational shifts you put them through.
Shift operational goals on a dime.
Need a maximum power, a 3-hour discharge one day, and a high round-trip efficiency over a 12-hour discharge the next? No problem. Because our Eos Znyth chemistry is highly tolerant of significant variation in operational requirements, any given Stack’s discharge depth and duration can be reset on a cycle-by-cycle basis. And all without any impact on the system’s total degradation or lifespan.
We’re charged to implement with ease and speed.
Eos Project Teams support customers from conceptual design through full turnkey system delivery. Our Project Managers and Engineers have broad project delivery experience and the hands-on knowledge to address the challenges capital projects face in meeting safety, quality, schedule, and cost expectations.
