Does an integrated DC disconnect count as a PV system disconnect?

It’s important to note that the integrated DC disconnect on the inverter does not count as a PV system disconnect, since it does not isolate all of the equipment as per the NEC definition – the AC side of the inverter is still connected to the utility load even the DC side of the inverter and the solar panels are disconnected.
