It seems you are correct. I don't see why there is so much resistance to the idea of a separate loads panel. They are easy to buy, install, etc. But the bigger issue is that this industry (like many others) is relying on influencers to promote their product, and sell them. Those people are being paid in many ways, such as free samples, discounts, affiliate fees based on links, etc.
No one has any means to verify what the background is of the person contributing. Many just follow online advice blindly, and the results may or may not be positive. It may not even be remotely legal. There are a lot of very intelligent, well-meaning people who contribute comments too. How does an average person decide how to proceed?
To my way of thinking, this is on the manufacturers. Why doesn't (for example) Victron get their equipment UL certified. Or Growatt, who sells huge numbers of this equipment here in the US. The excuse that it tedious and expensive is crap. I spent my career going around the world installing equipment that had to be certified for use at its point of installation. Canada, Asia, US, wherever. It requires employees, training, expenses.
But instead, we are discussing modifying a non-certified Growatt, to install and use in the US, with an auto-transformer that might not be certified.
I guess you get what you pay for. Right? I'm still upset that the company who told me my Victron inverter was UL certified were wrong, and I can't send it back and apply the money towards an Outback, SMA, or some other unit that is certified for installation according to US codes. So I won't be buying a Growatt, or anything similar.
All that being said, the last post by Hedges where he comes up with the bath tub scenario...I can actually envision that happening.
