Technical FAQs 4

What is a cube energy storage system?

The workhorse of energy storage. Like the Eos Z3 battery modules they house, our Cube is a self-contained unit—a closed-system design with no delicate internal or external moving parts like AC systems or flow pumps that degrade from continuous, daily wear and tear.

How many battery modules are in a cube?

Each Cube is loaded with 672 Eos Z3™ battery modules—the current generation of our zinc-powered Znyth™ technology. Designed to meet a wider range of needs. Simple, safe, durable, flexible.

How does the EP Cube storage system work?

The EP Cube storage system aesthetically and compactly integrates a hybrid inverter, UPS functionality and lightweight, stackable battery modules via plug & play connectors. Each module has a capacity of up to 3.3 kWh and weighs less than 35 kg, making it easy to transport, handle and install.

How many battery modules are in a EOS cube?

Shipped ready for deployment, our Eos Cube comes with all battery modules, electrical equipment, and the BMS pre-integrated into a standard 8 x 16-foot outdoor-rated shipping container. Each Cube is loaded with 672 Eos Z3™ battery modules—the current generation of our zinc-powered Znyth™ technology. Designed to meet a wider range of needs.
