If you want to service the inverters, you just open the AC disconnect which is the backfeed breaker.
If you want to work on one microinverter but not disable the rest, unplug it from the AC wiring harness.
To service a panel, unlike with a string inverter, you just disconnect that panel from its microinverter, with or without disconnecting the AC side of the inverter. The only thing you need to take care with is that you shut down the inverter or cover the panel before disconnecting the PV at an MC connector. Those connectors are not designed to be unplugged under load.[
