Solar Security Concerns: Undocumented Chinese Communication
Despite typical safeguards, including firewalls against direct communication, rogue communication devices have been uncovered in several Chinese solar inverters, raising
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.
These inverters link solar panels, wind turbines, and batteries to electric grids and are primarily manufactured in China. While they are designed for remote updates, U.S. utilities typically install firewalls to prevent unauthorized access.
