Note that the research is centered on Germany, where there is a bit more of a default-deny approach to electrical safety.
Here in the US, some of the pictures I've seen of sample finished installations that the installer is proud of have been downright scary. Like giant wall of 2V batteries with terminals coming out horizontally, open bus bars tying them all in series to make 48V, and then the leads going to the inverter just draped over the entrance to a wiring trough with a rough edge! There was probably a fuse as part of the inverter itself, but no protection for the batteries themselves.
I'm guessing it has to be a case of code inspectors not particularly caring or knowing about the DC side? Although with that kind of current capacity, perhaps the wiring itself is considered a fuse...
