Nexus in depth

Control, architecture, security, markets

Every technical layer of the Nexus platform, from closed-loop grid control to aggregator connectivity.

Security Framework

Zero-trust Architecture

No implicit trust: every connection is authenticated and verified before access is granted to any system resource.

Enterprise Authentication

Role-based access control (RBAC) with enterprise identity providers. Separate access levels for operators, aggregators, and administrators.

Encrypted Communications

End-to-end encryption for all data in transit. Secure channels between field controller, cloud, and user dashboards.

Audit Logs

Full immutable audit trail for all control actions, setpoint changes, and access events. Required for HEDNO compliance.

Certifications

ISO 9001

Quality management system certification for software development and project delivery processes.

ISO 27001

Information security management system. Covers data handling, access control, and incident response.

NIS v2.0

National Technical Specification compliance for grid-connected systems in Greece.

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.

Why Nexus

Built for BESS and Solar PV

Six reasons operators and aggregators choose Nexus over generic SCADA platforms.

Scalable

Cloud-native fleet management

From one site to a national portfolio — the same platform, the same dashboard, zero reconfiguration.

<600ms

7,000+ signals, 1-second loops

High-speed parallel data acquisition with sub-second response for real-time grid services.

Zero-trust

Enterprise authentication & encryption

Role-based access, encrypted channels, and immutable audit logs across all user and system interactions.

Redundant

Clustered PPC & dual storage

Redundant on-site hardware with automatic failover and dual cloud backup — no single point of failure.

Compliant

Full grid-code & DSO/TSO support

Pre-deployment validation, HEDNO certification, and continuous compliance monitoring built in.

AI/ML

Predictive analytics & fleet insights

Machine learning tools for anomaly detection, performance forecasting, and fleet-wide optimization.

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.
