Command, control & complete visibility
The Fractal EMS HMI enables control, active management and monitoring, P/Q response capability, and dashboards to monitor system conditions, safety controls, and faults & alarms.
Asset & fleet management
One interface to run your whole fleet
A flexible, scalable architecture lets you add, remove, or change assets and dispatch a single site or your entire portfolio while reliably managing your fleet.

Historian, data & reporting
Fractal EMS includes a data historian and custom report builder, hosting your data in our secure cloud — which manages storage, network security, node clustering and data replication for high reliability, performance and availability. Time-series data (typically 300–1,000 points per inverter) is available for all system equipment: PCS, battery racks and BMS, unit controllers, meters, sensors, fire panels, thermal management, switchgear, transformers and generators. All data is encrypted (including customer-provided data) and hosted with separate permissions for privacy and security.
