US investigation finds no evidence of spyware on Chinese power inverters

U.S. officials have found no evidence that malicious communication equipment is embedded in Chinese inverters used in the nation's power grid, according to an Energy Department?report.

Inverters are devices that convert the electricity produced by solar panels and batteries into electrical power for use in appliances. The inverters are designed to be remotely accessible for maintenance and updates.

The majority of power inverters in the world are manufactured in China. In part, this is due to the tense relationship between Beijing and Washington and concerns about national security. The DOE analysis was done in response to media reports stating that unexplained communications equipment was found in some inverters manufactured in China. Last year, we reported the existence of these devices.

The report, dated January 20, stated that "DOE assessments did not find any definitive evidence of malicious wireless functionality being intentionally introduced in the inverters tested."

DOE officials didn't immediately respond to a comment request on the report.

According to the analysis, the agency examined about?30 of inverters. It found two that were different from official documentation. The differences were "non-malicious" and "non-intentional."

Inverters, as well as any device with communication capabilities, are at risk of remote access. The report?added that it was unlikely for a single compromised inverter to have an impact on the grid.

It is recommended that purchasers of components are familiar with all the capabilities of the products. Reporting by Nichola Grroom, Editing by Chizu Nomiayama
