Most solar inverters in the Netherlands do not meet electromagnetic compatibility (EMC) requirements, which creates interference risks and increases the risk of hacking, says the National Inspectorate for Digital Infrastructure (RDI).
RDI’s research reveals that nine manufacturers’ inverters are non-compliant, posing a risk of interference and hacking. While all inverters meet minimum cybersecurity standards, they can be easily hacked and used for distributed denial-of-service (DDoS) attacks, RDI said.
Inverter manufacturers have a legal obligation to prevent the sale of disruptive products. Electromagnetic compatibility-related faults have increased significantly in recent years, likely due to an increase in solar installations, with 113 reported between 2020 and 2022, RDI said.
The Swedish Electrical Safety Agency conducted a similar study in 2021.
