No Fleet-Wide View
Plant managers juggle multiple dashboards, spreadsheets, and OEM portals. There is no single place to see the entire portfolio in one view.

THE CHALLENGE
Your Plants Are Generating.
But Are They Performing?
But Are They Performing?
Late Detection of Performance Issues
Faults and performance losses are identified only after energy is impacted, with no proactive alerting system in place.
Reports Built Manually
Performance reports for clients, lenders, or auditors are compiled manually every month, pulling data from disconnected sources with no audit trail.
THE SOLUTION
One Platform to Monitor, Analyse, and Optimise Every Asset Across Your Portfolio
Portfolio-Level Live Monitoring
Track every plant, every inverter, and every string across your entire fleet from a single cloud dashboard. Plant-wise and inverter-wise performance ranking updates continuously so your team always knows which asset needs attention first.
Portfolio-Level Live Monitoring
Monitor every solar plant, wind farm, inverter, and string across your entire renewable portfolio through a unified cloud-based dashboard.
- Fleet PR, CUF, MA, PLF and generation tracking (Day, MTD, YTD, custom range)
- Asset-wise performance benchmarking and ranking across technologies
- System-wide communication health and data reliability monitoring across all sites

AI-Based Inverter Health Intelligence
The Merlin Inverter Health Index (IHI) scores every inverter daily using multi-dimensional performance data. Degrading inverters are flagged before they fail, giving O&M teams time to act rather than react.

Wind Performance Optimization and Loss Intelligence
The platform identifies and categorizes energy losses specific to wind assets—such as wake effects, curtailment, turbine underperformance, and grid constraints. Each loss is quantified and linked to revenue impact, enabling operators to take targeted actions and maximize generation efficiency.

GEO Mapping
Topology-accurate fault localisation with live power flow. GIS layering lets operators drill from portfolio view down to string level without switching tools. Dynamic SLDs reflect real-time status for every asset in the plant.

HOW IT WORKS
Three Steps from Raw Site Data to Portfolio Intelligence
Data Acquisition & Management
Merlin LDMS hardware at each site collects inverter, weather, and meter data at 1 to 15 minute intervals. Multi-protocol support covers Modbus, IEC 61850, IEC-104, OPC-UA, MQTT, and HTTP. Data is validated and compressed before transmission.
Cloud Processing and Visualisation
Aggregated data flows to the Merlin cloud, where plant-wise and portfolio-level dashboards are updated in real time. GIS maps, SLDs, inverter rankings, and fault logs refresh automatically. No manual data entry at any step.
Analytics, Alerts, and Reporting
Loss bucketing, health scoring, anomaly detection, and compliance KPI calculations run continuously. Pre-emptive alerts are dispatched by role. Automated daily, monthly, and annual reports are generated without operator intervention.
Compatible with inverters, meters, and weather stations from all major OEMs
