Inverter integration

Direct Modbus TCP / IEC 61850 / SunSpec polling from string inverters and central inverters. Real-time power, voltage, frequency and fault codes per device.

Alert & alarm system

Rule-based alerting over inverter telemetry, grid events and weather-corrected production targets. Configurable severity tiers, escalation and notification delivery.

SCADA integration

OPC-UA and Modbus SCADA bridges for control-room integration. Live topology diagram with energy flow and per-string health visible at a glance.

Yield & revenue reporting

Automated daily, monthly and annual yield reports. PR trend charts, loss waterfall analysis and export for energy settlement systems.

Engagement deliverables

Protocol-native inverter integration

Direct Modbus TCP, SunSpec or OPC-UA polling from string and central inverters as installed on site. No vendor middleware required.

Portfolio and per-string dashboard

Multi-plant overview with per-string performance, irradiance-corrected PR, soiling flags and yield against budget — configured to the site layout.

Alarm rules tuned with O&M team

Alert thresholds defined with the site's O&M team during commissioning. Escalation tiers and notification delivery configured before go-live.

Yield and performance-ratio reporting

Automated daily, monthly and annual yield reports with PR trend charts and loss waterfall. Export-ready for energy settlement and O&M contracts.

Historical data retention and export

Time-series data retained in TimescaleDB with a configurable retention horizon. CSV and REST export for finance, compliance and third-party analytics.

Runbooks and handover documentation

Operator runbooks, protocol configuration files and system documentation delivered at project close. No proprietary lock-in.

FAQ

Questions operators ask first

Production integrations over Modbus TCP, SunSpec, IEC 61850, OPC-UA and MQTT. We poll string and central inverters for live power, voltage, frequency and fault codes, and add adapters for new models without rewriting the core.
Yes. The usual pattern is an operator layer on top of the SCADA you already run, not a replacement. OPC-UA and Modbus bridges keep the control-room view and add portfolio analytics, weather-corrected PR and alerting.
