Aside from vendor performance...
One of the great differences between made in China and made in the USA electrical and electronics is that products made in the USA get tested before they are wrapped in cellophane. Even John Marles, of Megawatt who uses far east parts in his products, but circuit boards made in Texas, tests his products before shipping. So does Meanwell, from Taiwan.
I mention this, not to criticize but to try and educate. I know of no company that sells converter products that have been operationally tested before shipping. Big companies use circuit testing that probe individual switching and control circuits. Be prepared to be the "Finished Product Guinea Pig". It is the hood ornament of our times and we have to live with it. But live with it as wisely as possible.
The whole RV is like that. They don't want to interrupt the line at the factory even if they find an "issue", so they find it is cheaper to send the Rvs out to the dealers and then solve any issues later under warranty. This keeps the line rolling, and some folks might not even notice the issue, so no warranty claims from them.
The 5er wee got brand new had a couple of foggy double pane windows, so the dealer tried to get replacements from the RV factory for us. Turned out the factory was behind in getting windows from their window vendor, so any new windows went straight into new trailers on the line, so we couldn't get any. Eventually after much pushing and shoving, our dealer managed to get the windows for us under warranty.
It is all about the production line and don't ever slow it down.
