Control hardware, assembled and tested in the U.S.A.
Every Fractal EMS controller is built in the United States with non-FEOC components, then pre-configured and tested before it ships — ruggedized for harsh environments and stringent uptime guarantees.

Controllers

1 per PCS
Unit Controller
Deployed on-site to monitor, control, and coordinate each unit — providing controls to the PCS, BMS, thermal management, and fire system.

1 per Resource
Power Plant Controller (PPC)
Single point of control and monitoring for a BESS, PV or genset subproject — runs all control modes and optimization, interacts with every inverter and battery block, and interfaces with external parties.

1 per project
Master Plant Controller (MPC)
Coordinates monitoring, control, and dispatch across all subprojects — storage, PV, or PV + storage — ensuring POI limitations are never violated.
Built tough for rugged environments
Hardened, industrial-grade controllers for utility and commercial applications
Enables energy storage plants to meet all competitive requirements
Efficient communication system with millisecond response time
Precise regulation of real and reactive power using closed-loop response
Individual control of the PCS and subcomponents
Compact design enables easy and fast installation
Digital and analog I/O modules for communication with third-party devices
Ingestion, diagnostics & reporting of BOP components, thermal management, fire panel, and metering
Configuration, parameterization & diagnostics via Fractal's web dashboard

Built in the U.S.A. — never a FEOC
Every controller and enclosure is assembled and factory-tested in the United States using non-FEOC components. Domestic hardware, domestic software, domestic support — no foreign supply-chain risk.
