What we are taking away from Brussels: inverters are becoming a security issue
REFU took part in the industry exchange in Brussels on cybersecurity, high-risk inverters and EU funding. What this means for operators, EPCs and investors.
On 19 June 2026, REFU attended the “Inverters Roundtable” at the European Commission’s Albert Borschette Conference Centre in Brussels. The exchange covered cybersecurity, inverters from high-risk countries and EU funding for energy projects.
The discussion showed that this is no longer just about PV inverters, but also about battery storage, power conversion systems and the bankability of future energy projects.
What this means for operators, EPCs and investors
- Anyone planning a PV plant or a battery storage system should clarify early on who can access the controls and where the data is processed.
- The origin and security architecture of components may become more important for funding and financing.
- For existing plants, it is worth reviewing communication paths and access rights. Many can be retrofitted.
