US energy officials have found unexplained communication equipment inside some Chinese-made inverter devices.

Reuters reported the presence of undocumented and “rogue” communication devices in a number of Chinese-made solar inverters. These could potentially introduce unregulated and undocumented remote communication channels to the inverters, by which an actor could remotely bypass the cybersecurity firewalls that utility companies use to prevent direct communication back to China.

Not naming the manufacturers is very disappointing
It is. So I looked it up:
According to the info I found, Huawei battery systems, and concerning solar panel electricity invertors they mentioned Sungrow, Growatt, and SMA. Growatt has arranged a patch, they claim.
Many of these Chinese systems have little to none (security) updates.
What makes you believe that those software issues from a month ago are in any way related to the undocumented communication hardware found now?
