I read it as a problem with solar panel voltage going over declared threshold of 37v in certain meteo conditions.
That is the issue is with the wrong labeling of things that are being plugged into this vendor's device, not the vendor's own labeling.

I agree the labeling is an issue here, but the solution must come from the wider industry or regulatory bodies; the alternative is for vendors to switch to their own pseudo-units to internalize the math, which would not be good for customers either - think "ACME Generator2000 accepts up to 4 Power Units of input; each ACME SuperEco Panel supplies 1 Power Unit, or 1.5 Power Units if you're in Canada...".
Saving users from having to do a little thinking to not brick their device is a tried-and-true excuse for vendor lock-in in our industry :).
Completely unhelpful to those that need the info.
Nobody seems to remember a bunch of companies receiving rather large fines for pulling known bull-crap "may contain sesame."
The label on the modules themselves tend to also provide these ratings at STC, e.g. this label from Jinko specifies the Open circuit voltage and also summarizes the conditions assumed for STC:

While I agree that the label could also add the temperature coefficient, I'm not sure if it's reasonable to expect that specialist electrical equipment details all of its operating parameters on an attached label without the expectation of consulting a datasheet or manual. For specific products that primarily target non-specialised consumers however, a different labelling approach may be warranted.
