However, undocumented communication devices have reportedly been found in some Chinese solar power inverters. And over the past nine months, such devices—including cellular radios—have also been found in some batteries from Chinese suppliers.
Every solar panel and battery connected to the U.S. energy grid relies on a device few people ever consider: the power inverter. In May of 2025, U.S. experts found undocumented communication modules and secret radios embedded in some Chinese-manufactured solar inverters and battery systems.
In a discovery that has sent shockwaves through the cybersecurity community, U.S. energy officials have found undocumented "rogue" communication devices hidden inside solar power inverters imported from China.
While such inverters allow remote access for updates and maintenance, utility companies usually install firewalls to block direct communication back to China. However, undocumented communication devices have reportedly been found in some Chinese solar power inverters.
Over the past nine months, undocumented communication devices, including cellular radios, have also been found in some batteries from multiple Chinese suppliers, one of them said.
