Rogue undocumented communication devices have been found inside some Chinese-made solar power inverters since mid-2024, raising security concerns globally. The discovery follows ongoing U.S.-China tensions and concerns about vulnerabilities in critical renewable energy infrastructure, with exact device numbers and intent remaining unclear.
Experts warn that these hidden cellular radios could bypass firewalls, remotely switch off inverters, alter settings, destabilize grids and cause widespread blackouts affecting power stability. Huawei leads inverter production with 29% global market share in 2022, while U.S. and European authorities respond with legislation and supply chain efforts to limit Chinese influence over energy grids.
These events have prompted U.S. energy officials and NATO allies to reassess strategic dependencies and accelerate domestic manufacturing to reduce risks to critical infrastructure.
