Chinese control of our grid connected solar inverters
They will hardly close a hole in their exposure by removing Chinese kit when many of the most popular brands of solar inverter being installed in the UK operate by connecting to Chinese manufacturers cloud systems. They can still mess with our grid by adjusting power settings on the edges of the grid.
Thousands of inverters all adjusting frequency or voltage at the same time will have a big impact on the whole grid. To top that off these cloud systems have details of location, and I am sure the national grid layout is available so taking down a section is as easy as adjusting systems in specific locations and hey presto overloaded critical interchange, bye bye power in targeted area.
