New investigations reveal undisclosed communication devices within Chinese-made solar inverters, raising alarms over potential energy grid vulnerabilities and prompting
U.S. energy officials have launched an investigation after discovering unauthorized communication equipment embedded within Chinese-manufactured solar power inverters connected to critical infrastructure grids across the country.
These inverters, which are essential components that convert direct current from solar panels into alternating current usable by the electrical grid, were found to contain undocumented cellular radio devices not disclosed in product specifications or technical documentation.
Leading renewable energy operators worldwide are confronting a disturbing supply-chain vulnerability: undocumented communication modules found in Chinese-made solar inverters and batteries.
“Ten years ago, if you switched off the Chinese inverters, it would not have caused a dramatic thing to happen to European grids,” said Philipp Schroeder, CEO of German solar developer 1Komma5. “But now the critical mass is much larger.” By some estimates, more than 200 gigawatts of solar capacity in Europe is linked to Chinese-made inverters.
