The PV system DC disconnect must be identified as such, and it must be suitable for the prevailing environmental conditions [690.14(C)(2)]. Utility-interactive inverters can be mounted on roofs or exterior areas that aren''t readily accessible if: The PV system DC disconnect is within sight of or in the inverter [690.14(D)(1)].
That disconnect does isolate the PV power source from the rest of the system but it does not isolate all of the PV equipment. The DC disconnect will stop the inverter from producing power but the AC side of the inverter will still be connected to the utility.

DC Disconnect: 690.13(b) - This label shall be installed at each PV system disconnect, which is usually integrated with the inverter. There could be a separate DC disconnect not located in the inverter, if so, this label would be installed on the separate DC disconnect. There is no color requirement for this placard.
NEC 690.13(B) Each photovoltaic system disconnecting means shall be permanently marked to identify it as a photovoltaic system disconnect. NEC 690.15, IFC 605.11.3 If the equipment is energized from more than one source, the disconnecting means must be grouped and identified. NEC 690.16(B) Non-load break rated disconnect means shall be marked.
(5) Maximum System Voltage: (NEC Article and Table 690.7, page 512) Maximum system voltage is calculated by multiplying the value of Voc (open circuit voltage) of the PV module by the appropriate value on Table 690.7 in the NEC, and then multiplying that value by the number of modules in a series string.

The DC disconnect will stop the inverter from producing power but the AC side of the inverter will still be connected to the utility. Therefore this wouldn''t be considered the PV system disconnect as not all the PV equipment is disconnected. Of course, it wouldn''t be Code if there weren''t special cases and exceptions.
