Technical FAQs 4

What are hidden communication devices in solar energy equipment?

U.S. energy officials have discovered hidden communication devices in solar energy equipment supplied from China. These are primarily inverters used to connect solar panels and wind turbines to power grids, as well as batteries, heat pumps, and chargers for electric vehicles.

How do solar inverters work?

The inverters are part of the hardware package connecting solar arrays to the power grid. The package includes communication devices so technicians can monitor performance and have remote access for maintenance. These devices are disclosed in what’s called a software bill of materials – a listing of the components that comprise the package.

Are Chinese solar inverters connected to the power grid?

U.S. officials have discovered undisclosed communication devices on the power inverters of some Chinese-manufactured solar panels, Reuters reported today based on anonymous sources within the federal government. The inverters are part of the hardware package connecting solar arrays to the power grid.

How many rogue communication devices were found in Chinese solar inverters?

The number of devices investigated was also not disclosed. This follows discovery of rogue communication devices not listed in product documents in some Chinese solar inverters, according to Reuters. The devices were reportedly found over a period of nine months and include communication devices such as cellular radios.
