Technical FAQs 4

Are hidden communication devices in Chinese-manufactured solar panels a threat?

Recent findings have uncovered hidden communication devices within Chinese-manufactured solar panels, sparking serious concerns over the security of national power grids.

Do Chinese solar power inverters have undocumented communication devices?

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.

Do Chinese solar power inverters have a firewall?

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.

Could Chinese solar power inverters destabilise power grids?

Solar panels are seen with a view of the neighbourhood and lower Manhattan in New York in this August 2022 file pic by Reuters. Western nations have raised a security alert after US experts found “rogue communication devices” in Chinese solar power inverters, amid concern they could be used to destabilise power grids.
