Technical FAQs 4

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.

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.

Are Chinese solar power inverters Rogue?

Rogue communication devices have been found in some Chinese solar power inverters and batteries, two people familiar with the matter told Reuters, raising concerns of potential security risks in U.S. renewable energy infrastructure. Power inverters are used to connect solar panels and wind turbines to electricity grids.
