Product Value
Project fit, core capabilities and delivery value
An edge EMS for C&I storage, microgrids and distribution-area storage, supporting up to 30 cabinets in a ring network.
Connect PCS, BMS, meters, PV, charging piles and auxiliary devices with core strategies at the edge.
One controller per cabinet enables plug-and-play ring-network expansion.
Core Modules
Access, control and O&M in one loop
Connect field devices, execute strategies and protection at the edge, then synchronize reports, alarms, configuration and resources with the platform and app.
01 Device Monitoring
PCS/BMS and Auxiliary Access
Connect PCS, BMS, meters, PV, charging piles and auxiliary devices in one edge controller.
- PCS/BMS access
- Auxiliary control
02 Load Tracking
Local Strategy and Safety
Track load power and execute reverse-power, demand-overrun and protection strategies locally.

- 04FeiStorage App
Storage Device Access
Connect PCS, BMS, meters and cabinet auxiliary devices.
Local Storage Control
Run charge/discharge, safety and revenue strategies at the edge.
Cloud O&M Coordination
Synchronize operating data, alarms and reports with FeiCloud and the app.
Core Capabilities
Capability
Edge execution, cloud coordination, remote O&M, data retention and safety support delivery.
Capability 01
Device Access
Built-in time-of-use tariffs, seasonal tariffs, charge/discharge schedules and revenue accounting models; the edge executes according to strategy while the cloud reviews revenue deviations daily, weekly and monthly.
Capability 02
Strategy Execution
It collects gateway meter, PCS, BMS and load power in real time, dynamically adjusts energy storage charging and discharging, and triggers relay protection when necessary to prevent reverse feed-in and transformer limit violations.
Capability 03
Safety Protection
For standard outdoor cabinets, it provides ring-network dual-network backup and multi-cabinet parallel capability, reducing the number of switches, network cables and commissioning points, and making C&I projects easier to replicate.
Capability 04
Remote Operations
The edge EMU executes protection and strategies, while the FeiCloud platform handles remote diagnostics, alarm work orders, version consultation and multi-site operations dashboards.
