A growing wave of concern has emerged in the United States after American cybersecurity experts discovered hidden cellular communication components embedded in Chinese-made solar inverters installed across solar farms in the country.
In May of 2025, U.S. experts found undocumented communication modules and secret radios embedded in some Chinese-manufactured solar inverters and battery systems. Not listed in product documentation, these shadow components create hidden backdoors that can circumvent utility firewalls and allow remote access to the devices.
If not, China will continue to evade state-specific bans, with new vulnerabilities capable of emerging from wherever inverters are produced next. Undocumented radios found in Chinese-made solar inverters pose a threat to U.S. energy infrastructure and security, enabling disruption of critical systems.
Over 200 gigawatts of European solar capacity (equivalent to more than 200 nuclear power plants) are tied to Chinese-made inverters.
