Solar edge - hd wave inverter monitoring question and misc.

Hello,
First time here. I just installed ( yet to be inspected) a grid tied solar system on a detached building. 33 420 watt panels with solar edge optimizers and solar edge had-wave inverter. In order to monitor our system do I need wifi in the shop? I bought the wireless gateway + antenna with the system, however, it needs to plug into a router with an Ethernet cable. If I need wi fi in the shop, I’m thinking a p2p system as running a ethernet cable is not an option.
2nd question - what pv labels are required on equipment under the international building code?
3rd question - my system has solar edge optimizers and a dc disconnect between the inverter and sub panel. This is all inside my shop. Does the dc disconnect need to be outside?
Thank you in advance

The solar edge inverters without a display have wifi built in, and should be able to connect to wifi router during commissioning. There is also a cell modem that comes with 5 years of service that is available if wifi isn't an option.

This documents many of the common label requirements: https://commerceri.com/wp-content/uploads/2023/08/PV-Labeling-2023-NEC-RI-REF-1.pdf

The DC disconnect doesn't need to be outside, but a disconnect needs to be outside and in an accessible location, and labeled as the PV rapid shutdown switch, this could be a DC disconnect, but can also be any disconnect new or existing that shutdowns AC power to the inverter.

Thank you for the information. One additional question will a breaker work as a rapid shutdown switch? Or will I need to add another disconnect. The breaker is on an exterior meter panel.

In the cities I’ve seen friends’ systems and done my own, a labeled exterior breaker is fine, and in some cities even shutting down the whole house is fine in mine. (Microinverter systems). But it varies by AHJ. For the plans I hired out for they initially put an annoying PV only separate physical disconnect. I didn’t want to pull that extra 60 foot loop so I told them my AHJ does not need that.
