China sabotaging U.S. solar arrays

I have always been concerned about the quality and security of products imported from China. Their quality control is abysmal, and over the decades, there have been many instances of poor-quality imports from China, including lead paint in toys, contaminated pet food and toothpaste, faulty mass transit vehicles, radioactive dry wall, carcinogenic fish, and contaminated candy. Another major concern is the possibility of China intentionally building in failure of their products, which could compromise the proper functioning of U.S. systems.  

It was recently reported that Chinese “kill switches” have been found in solar arrays at U.S. solar facilities. They were found inside power inverters manufactured by Chinese companies. The power inverters link solar or wind farms with the overall power system. The kill switches can be remotely activated, and this occurred at a location in the United States in November. 

Chinese companies provide about half of the solar power inverters in the world, and any widespread control of power grids could compromise operations, cause widespread blackouts and endanger national security. Communist China is an adversary who could sabotage products and systems shipped to the United States. People, companies and government agencies should be wary of Chinese products and conduct in-depth testing of the products before accepting them.
