Building the next generation of PV inverters
For a more flexible, secure and resilient European energy system.
About SUNVIBE
SUNVIBE (Smart Upgraded iNverter architectures for Versatile and flexible Integration of PV-Based systEm) aims to develop a new generation of smart PV inverters to help solar and energy storage systems connect to and support Europe’s electricity grids more effectively.
The project brings together advanced inverter designs, built-in monitoring and diagnostics, secure data exchange and new grid-support controls. These solutions help solar systems operate more efficiently, communicate securely with other energy assets and respond better to changing grid conditions.
SUNVIBE tests its technologies through three pilot demonstrations in Finland, France and Spain, covering different types of solar and energy systems. The demonstrations show how smarter inverters can improve reliability, flexibility and power quality, helping Europe integrate more renewable energy into its electricity system.
Why smart inverters are needed
Growing pressure on grid stability
As renewable generation grows, electricity grids face more variable and decentralised power flows, increasing the need for reliable voltage and frequency control.
Limited secure digital integration
Many inverter-based assets lack integrated monitoring, data exchange and cybersecurity, limiting intelligent and secure operation.
Fragmented interoperability
PV systems, batteries and grid operators often use different technologies and data structures, making coordination and flexibility more difficult.
SUNVIBE’s response
Strengthening grid stability
Advanced controls will support voltage and frequency regulation, synthetic inertia and other grid services.
Enabling secure digital integration
Built-in monitoring, diagnostics, data management and cybersecurity will support smarter and more secure operation.
Improving interoperability
A harmonised data ecosystem will enable smoother interaction between PV systems, batteries, grid operators and other energy assets.
Built for secure, reliable
and responsible deployment.

The SUNVIBE logo reflects connection and energy flow between solar technologies and the electricity grid. Its connected forms evoke energy movement and conversion through smart inverter systems, and the visual identity reflects the project’s focus on flexible, secure, and coordinated energy integration.
Expected impact
SUNVIBE aims to turn PV inverters into active grid assets that support a more resilient renewable-based energy system. The solutions will help increase energy yield and system availability, reduce conversion losses and curtailment, strengthen flexibility services, and support the wider use of smart solar-grid solutions across Europe.
