Frequently Asked Questions

Have questions about our EMS? Some of these might help.

What equipment can the EMS integrate with?

The EMS communicates with PCS/inverters, BMS/battery racks, AC metering, site sensors, and optional PV/load signals. It uses Modbus (TCP/RTU) as a standard interface and supports extensible integration layers for other industrial protocols.

How does the EMS optimize energy costs?

The EMS performs constraint-aware dispatch using real-time data and operator-defined limits. It supports peak shaving, tariff/TOU scheduling, PV self-consumption optimization, and dispatch following—helping reduce energy costs while protecting battery health.

What happens if communication is lost?

The EMS includes built-in fallback behavior. In case of degraded communications or missing inputs, it can hold the last safe setpoint, revert to a predefined safe mode, and generate alarms to ensure continued safe operation.

Does the EMS provide alarm notifications and diagnostics?

Yes. The system includes alarm classification by severity, acknowledgement workflows, root-cause correlation, communication health monitoring, and configurable notifications via email, webhooks, or third-party integrations. It also maintains audit-ready logs of operator actions.

What reporting and export capabilities are available?

The EMS provides daily and monthly performance summaries (energy throughput, availability, uptime, utilization, peak reduction), alarm/event reports, CSV exports, and API access for integration with external systems. Compliance or contractual KPIs can also be supported when applicable.
