U.S. Engineers Find ‘Rogue Communication Devices’ in Chinese Solar Panels

"U.S. engineers have discovered mysterious, undocumented communication devices lurking in some Chinese-made solar power inverters and batteries.

“The rogue components provide additional, undocumented communication channels that could allow firewalls to be circumvented remotely, with potentially catastrophic consequences,” said Reuters’ sources.
In the case of the suspicious Chinese power inverters, the devices were designed to connect solar panel arrays and windmills to power grids. They have Internet capability, so their performance can be monitored and their software can be updated easily."
