so it looks like a shielded 5 conductor control bundle might work?

August,
I am not answering your question but SMA tech support folk have
specifically told me that putting our 600V jacketed control wire in the
same EMT as the DC strings is leading to false arc fault trips.

Hi Wrenches,
I’m preparing for 2014 NEC 690.12 Rapid Shutdown to hit in California
January 2017. Specifically, I’m trying to determine what to do for new
string inverter based installations. I’m assuming that microinverter, AC
modules, and systems with power-level electronics (SolarEdge etc) are
innately compliant.
I spent a while researching SMA’s rapid shutdown system. It appears that
we need five 16 or 18 AWG conductors for the control circuit. Any
recommendations on what type of wire to use assuming we run it in our EMT
run down from the roof to inverter? Tray Cable might work?
Best,
August
