SCADA for Photovoltaic (PV) Plants

Rener Energy’s SCADA solution for PV plants provides complete visibility and control across the entire installation — from string level to grid connection point. Built to maximize performance and uptime, the system enables operators to monitor production, detect inefficiencies, and respond instantly to any event.

The platform integrates seamlessly with all major equipment vendors and communication protocols, ensuring reliable data acquisition and centralized control of the plant.

Key capabilities

  • Real-time monitoring of energy production and plant performance
  • String, inverter, and substation-level data visibility
  • Fault detection and alarm classification in real time
  • Power quality monitoring (voltage, frequency, harmonics)
  • Remote control and curtailment capabilities
  • Integration with weather stations and forecasting tools
  • Historical data analysis for performance optimization
  • Full compliance with grid operator requirements

Integration process

How your plant goes live in Nexus

We start from your real equipment, not a generic template.

1

Technical Site Mapping

We document capacity, BMS, PCS, meters, MV/LV, communications, and project obligations on-site.

2

Redundant Controller

We install the clustered PPC Advantech MIC-770 V3 with automatic failover and all field accessories.

3

Protocols & Network

Modbus, IEC 61850, IEC 104/101, MMS & GOOSE in the field and IEC 104 toward HEDNO, with supervision UI.

4

Live Operations & Market

Closed-loop control, live monitoring, alarms, setpoints, and data ready for aggregator workflows from day one.

Battery storage (BESS) and photovoltaics, with or without a data logger — multi-vendor inverters, BMS, PCS, MV/LV, and cooling and fire-suppression subsystems are all supported.

Closed-loop PID for active and reactive power, ramp rate control, power factor (cos φ), frequency support (FSM ±200 mHz, LFSM-O/U), voltage droop, SoC band management, and grid-forming for black-start. All algorithms are configurable per grid code.

Modbus TCP and RTU, IEC 61850, IEC 104, IEC 101, MMS & GOOSE in the field. IEC 104 toward HEDNO for grid operator communication. HEnEx/IPTO data interfaces for market connectivity.

7,000+ signals delivered in under 600ms via parallel connections. 1-second monitoring loops. Redundant on-site PPC with automatic failover and dual cloud storage ensure high availability. All proven in production across 5 commissioned plants.

Nexus is designed to work with every aggregator platform. Setpoints from the aggregator are executed in real-time via the closed-loop EMS. Full HEDNO compliance for DSO/TSO telemetry, and live HEnEx/IPTO data feeds for market operations.

Yes. Nexus is built on a zero-trust architecture with enterprise authentication, end-to-end encryption, role-based access control, and full audit logs.
