Introducing Edgestack

Edgestack is a commercial energy storage system that discharges when needed to flatten your facility’s energy load profile, enabling you to benefit from significantly reduced demand charges. The fully-integrated system is available in 500 kW building blocks that can be easily configured to meet the needs of individual facilities and aggregated across fleets or locations without time-consuming redesigns.

Built using our sixth-generation technology stack, Edgestack incorporates more than 13 years of design and deployment experience.

The Fluence Technology Stack

The Fluence Tech Stack combines hardware, controls, software, and intelligence into an integrated foundation for safe and repeatable energy storage systems that are tailored to your use case and application.

Fluence Cube

Modular, factory-built, standardized form factor delivers safe, scalable, cost-effective systems configurable with the latest storage components.

Fluence OS

Fully integrated operations platform combines comprehensive controls, asset management, and system visibility across single sites or entire fleets.

Fluence IQ

Extensible digital intelligence improves system decision-making, asset performance, and operating costs with data-driven insights and dispatch algorithms.

The Edgestack System


Built on our sixth generation technology, Edgestack’s fully assembled, factory-built storage system makes it easy for you to install and operate. The system’s compact design fully integrates all components: batteries, racking, inverters, safety features, HVAC, and software control systems.

Quiet and emissions-free, Edgestack occupies a small footprint and can be sited at nearly any commercial or industrial location.

Fleet Optimized

Edgestack adopts a customize-and-scale approach, allowing you to configure the system to meet your requirements, and then deploy across a fleet of your facilities or operations. This repeatable structure drives efficiencies in project design and permitting, enabling fast delivery and rapid installation. Likewise, consistency across project locations simplifies training, operations, and maintenance for your team.

With an easy-to-use interface, Fluence’s fleet management capabilities give you remote visibility into all your storage assets simultaneously with real-time key performance indicators and fleet-level information.

Total System Safety

Edgestack’s comprehensive safety features span its integrated hardware, software, and intelligence technology stack.

Designed to meet industry-leading safety standards, such as UL9540, UL9540A, and IEC compliance, Edgestack is equipped with emergency shutdown, system limits, fire suppression, incipient gas detection, deflagration panels and more. Safety is embedded throughout every level of Fluence OS, which continuously monitors, detects, and alerts operators to potential anomalies.

Hardware-enabled safety measures

Subsystems protect themselves in event of a fault or failure in another subsystem, with all components having undergone rigorous qualifications and certifications.

Robust Network and Cybersecurity Management

Our energy storage technology contributes to critical infrastructure around the globe. To protect our customers and their networks from malicious attacks, Fluence complies with industry-leading cybersecurity practices.

We follow the National Institute for Standards and Technology (NIST) Cybersecurity Framework to incorporate the latest security features, including high-grade, 256-bit encryption, enterprise-class network security and firewall protection, multi-factor authentication, weekly vulnerability scanning, and more.


Fluence systems include enterprise-class network security, with firewall software monitoring and controlling all local network traffic.

Secure, role-based user access is done via VPN with multi-factor authentication and 256-bit encryption.

In transit

High-grade, AES 256-bit encryption is used to protect all data in transit from local systems to virtual private cloud (VPC).

Data in transit takes place over secure, site-to-site VPN tunnels.

In the cloud

A secure, logically isolated cloud environment uses restrictive firewall and security group rules to limit connectivity within the VPC.

All external access to the cloud is done using VPN with multi-factor authentication.
