Suite5 in SUNVIBE

In SUNVIBE, Suite5 leads the work packages behind the project's transversal digital layer (WP10–WP11) and develops the SUNVIBE data space for PV–inverter–battery–grid integration. The work delivers a harmonised semantic model covering inverters, batteries, PV modules, EVs and demand-side resources, extending open standards and ontologies — IEC 61850, 61968 and 61970, SAREF4ENER and SAREF4GRID, SunSpec, OpenADR 3.0, Modbus and OCPP — to the flexibility concepts and emerging assets they currently model poorly. Around that model sits the machinery that makes it usable: a standards-based connector for harvesting inverter data over SunSpec Modbus, data governance, sovereignty and quality-enhancement services, an API gateway for sharing curated data with other components and stakeholders, and MQTT/Kafka publish–subscribe channels for raw real-time streams. The data space is deployed across all three pilots, in Finland, France and Spain, giving the project's predictive maintenance, digital twin and coordinated PV–storage tools a common view of the same assets.

Suite5 also develops SUNVIBE's data-driven predictive flexibility services: an application environment for aggregators and flexibility managers, built around a VPP Configuration Engine that groups distributed assets into market-compliant flexibility products. The engine works from AI-driven flexibility profiles and accounts for DER capabilities, location-specific constraints, contractual commitments and market participation thresholds, reconfiguring products as grid conditions, asset availability and market signals change. Both the data space and the flexibility services are Suite5-owned results, carried into the company's commercial portfolio after the project.
