I thought you could use 230.82(1) instead of (6) when installing without the last part, "if provided with a disconnecting means listed as suitable for use as service equipment, and overcurrent protection as specified in Part VII of Article 230."
But I don't think it would be compliant anymore. I went back to 705.11 and realized it specifies 230.82(6).
I have seen them spec-ed out on solar plans before, but now I don't know why. (P.S. They had SUSE for the solar install). I thought they did it to limit available fault current or something. The install was based on the NEC 2017. This was a couple of years ago. Maybe it was required by the UL inspector.
The 2017 NEC had distance limits between where the service conductors were tapped and the PV disconnecting means. Cable limiters allowed one to increase the distance.
This was before NFPA finally went in the direction of treating a PV supply side connection as basically just another service disconnect.
