If I have a system ..

4 strings of 12.5kw panels>IQ7+ inverters>Enphase Combiner w/ Envoy>AC Disconnect>Load Side connection to main panel

Do the hot legs of the dedicated Envoy circuit need to go through the AC Disconnect?

Envoy hot and ground legs going through AC disconnect is how the line diagram on my engineering plan is at present (which is not finalized). But if rapid shutdown happens at the microinverter level, is there a reason why it have to go through the AC Disconnect?

Based on location/distance factors running wire directly from main to Envoy gives me a ton of benefits. It would make 90 foot attic and wall run from [9 #10AWG wires] down to [3 #8 AWG wires], allow me decrease conduit size from 3/4" down to 1/2", and also it would eliminate the need for a 5 thhn ground wire irreversible splice in an attic junction box. Also reduces calculated total resistance of the system.
