U.S. authorities find no definitive evidence of hidden devices in Chinese solar inverters

U.S. government analysis of Chinese-made inverters has found “no definitive evidence” of malicious wireless functions, according to a report seen by pv magazine examining the scope of wireless communications in inverters and the risks they pose.
The US Department of Energy (DOE) has shared its analysis with energy sector partners following media reports that indicated the presence of undocumented wireless communications in Chinese-made inverters, first broken by Reuters in May 2025.
The DOE’s National Laboratories inspected “approximately 30 inverters” and found two cases where observed communications differed from official documentation, but these were deemed “non-malicious” and “non-intentional”.
In its analysis, the DOE noted “as built” documentation often reflects only activated communications features, meaning owners and operators of inverters should verify the communication protocols on their device and disable those that are not needed. The analysis notes manufacturers could maintain access for warranty or safety purposes, but this is often specified in contract terms “as required.”
The DOE did warn that supply chain threats persist, and the “complexity of inverter supply chains” could create opportunities for cybersecurity breaches and malicious components. The department noted that undocumented or implanted communications in a single inverter would be “unlikely” to have grid-wide impacts, but coordinated manipulation across multiple sites could have larger effects, although such an attack would be more difficult to execute.
Managing supply chain risk was described by the DOE as a responsibility shared among engineers, manufacturers, integrators, service providers and system operators. The department highlighted its Supply Chain Cybersecurity Principles for suppliers and suggested operators adopt these for security and resilience activities.

Korean companies strongly argue that they have found no signs of security concerns so far.
"There have been no confirmed cases of suspicious equipment being found in inverters," a spokesperson for Hanwha Qcells told the Korea JoongAng Daily. "China-made inverters are cost-effective with reliable quality, while domestic capabilities in inverter manufacturing remain limited, with few local companies involved in production."
