Next-Generation Intelligent Solar Inverters for Industrial and Utility-Scale Power Systems

energyPilotedTRL 7

Imagine the solar inverter as the brain of a power plant that decides how electricity flows between panels, batteries, and the grid. This project makes that brain smarter and more powerful, allowing it to handle much larger amounts of energy without wasting space or heat. It also adds a digital safety shield to prevent crashes and cyber-attacks.

The business problem

What needed solving

Current solar inverters often lack the flexibility to manage combined PV and storage efficiently at scale, leading to higher system costs and vulnerability to grid instability or cyber-attacks.

The solution

What was built

Two modular inverter platforms (low and medium voltage) featuring a 3 kV DC link, grid-forming firmware, and real-time health monitoring sensors.

Frequently asked

Quick answers

How does this affect the total cost of solar installations?

The medium-voltage design utilizes a 3 kV DC link and wide-bandgap semiconductors specifically to reduce balance-of-system costs.

Can this be scaled to large power plants?

Yes, the project develops two platforms covering commercial, industrial, and utility-scale needs, including a medium-voltage version for high-capacity use.

What is the IP and licensing status of the technology?

Based on available project data, the project focuses on creating interoperable communication frameworks and cybersecurity measures ready for standardisation.

Does the system comply with current energy laws?

The project includes grid-forming firmware designed to align with emerging European codes.

How is the system protected from hacking?

It implements cyber-physical safety through reflex functions that protect hardware and grid stability during remote command execution.
