This situation with SolArk /Deye has been going on so long (several decades) that it boggles my mind that people still find it surprising. It just shows you how little people pay attention to what is going on around them. I get the fact that it upsets people when they "learn" about this, because it bothers me too. Anyone old enough to remember the early TV days when Curtis-Mathes was a big deal might remember the shock and outrage when people began to discover that their super expensive "American made TV" was actually Japanese components brought in and stuffed into a wooden box here in the States. Intel and others have been doing kind of thing that for what, 40-50 years now?
It is a natural progression of economics that as various countries develop their manufacturing capabilities, they trade with each other, and contribute what they have to that scenario. It could be cheap labor, capital, technology, raw materials, etc. And that has been going on forever.
What is more disturbing (IMHO) is that especially in the US, we are so focused on acquiring goods and services that everything comes down to making a profit. Money. Money Money. Don't worry about homelessness, drug addiction, lack of critical life and job skills, retirement funds, staying healthy, etc...just Make America Great Again. How? Meanwhile, instead of making inverters here in the US, SolArk went to a Chinese company (Deye) and worked with them. Why? Because people here want lots of crap, and they want it cheap. In spite of the massive amount of information floating around the world on the internet, we really are not very well informed as a society. Who are the sources of information? How do you vet that information? Or, do you just believe what you choose to believe, or what your friends say? That is what most people do.
Meanwhile, the gap between the haves, and the have-nots is growing incredibly fast. No one in Washington is doing squat about the real issues, because we just keep buying into the same old line of crap, and we throw things away when they fail to work. And as long as that continues, other countries will continue to supply us with what we truly want...cheap goods. When Japanese-made products became so good that people clamored for them, I recall being surprised that my employer (Japanese) was sub-contracting our work to Korea, Thailand, Vietnam, etc. And no one in the US knew it. I worked in the same industry with a company that made most of its products here in the US, but they started doing the same thing, and having them made in Korea. They just didn't tell people. One of my best friends nearly had a heart attack when he discovered that his $10,000 "US Made" amplifiers were made in China. And so it goes on......
So back to the topic of EMP: if you are worried that it will hit your solar equipment, how well are you prepared for foodstuffs, water, hygiene, weapons, water filtration, medications, decontamination supplies, etc? Do you have spare circuits boards in a Faraday cage to repair your car, radios, phones, or what-ever devices? Do you actually know how to repair any of those things?
It bothers the crap out of me that we continue to rail against isolated issues like the SolArk/Deye scenario while blindly ignoring the behavioral issues that are the root cause. One of the greatest minds of our time (Noam Chomsky) contends that it is one of the greatest misconceptions of our "democracy" that we are free to express ourselves and our opinions. But it is simply window dressing to keep us placated while the reality is that it is getting much, much worse. My apologies to Noam if I have garbled his message.
So what can you do about it? Learn. Get out and make a diffrence. Demand action. Boycott companies who don't pay taxes here, and ship all our jobs overseas while making billions and billions in profits. Or just go watch TV.
