So you must have a combiner box between the panels and the conduit, confirm?
I was going to put switches for each string at the panels in case I need to work on them and a combiner box at the inverter in case I need to shut down a string in case of over voltage if that make sense, it’s Alabama, The temperature swings a lot here, unless you have other thoughts

You will need a junction box to go from pv wire to conduit.
