6 FAQs about [Photovoltaic inverter fraud case sharing]
Are PV inverters a cybersecurity threat?
A company spokesperson told pv magazine that the problem has since been resolved. The state-run Dutch Radiocommunications Agency has launched an investigation into whether PV inverters pose a threat to the cybersecurity of the electricity system in the Netherlands, according to Dutch Minister for Climate and Energy Rob Jetten.
Are PV inverters a threat to the electricity grid?
In a document published on the Dutch parliament's website, Jetten said that Internet of Things devices such as PV inverters can pose a risk to the electricity grid. “To mitigate the risks of these devices, we focus on prevention, awareness, and additional legislation that makes products more resilient to digital attacks,” he said.
Are photovoltaic systems vulnerable to cyber-attacks?
Photovoltaic (PV) systems, as critical components of the power grid, have become increasingly reliant on standard Information Technology (IT) computing and network infrastructure for their operation and maintenance. However, this dependency exposes PV systems to heightened vulnerabilities and the risk of cyber-attacks.
Are photovoltaic systems guaranteed or endorsed by the publisher?
Any product that may be evaluated in this article or claim that may be made by its manufacturer is not guaranteed or endorsed by the publisher. Photovoltaic (PV) systems, as critical components of the power grid, have become increasingly reliant on standard Information Technology (IT) computing and n
Are solar inverters a cyber risk?
Historically, cyber risk for solar was relatively minor, given how few systems were deployed and because most solar inverters did not communicate for monitoring or control. However, as more solar is installed and inverters become more advanced, this risk grows. Inverters are the interface between solar panels and the grid.
Is SolarEdge suing Huawei over patent infringement?
The Chinese company informed last week that the Mannheim regional court had dismissed SolarEdge's lawsuit against Huawei over infringement on the patent regarding optimiser and inverter architecture.
