Technical FAQs 4

Are Chinese solar power inverters connected to critical infrastructure grids?

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.

Do solar inverters contain undocumented cellular radio devices?

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.

Are Chinese inverters a threat to solar power?

This vulnerability is especially dangerous given the growing penetration of solar power on Western grids, where in some regions, Chinese-manufactured inverters control upwards of 200 gigawatts of generating capacity – equivalent to more than 200 nuclear power plants.

Are there undocumented communication devices in solar panels?

Over the past 9 months, undocumented communication devices (including cellular radios) have also been found in solar panels from several Chinese suppliers. The exact number of inverters and batteries tested, as well as the names of the suppliers, were not provided by the source.
