Finally pulling the trigger on my system expansion. Bought some Boviet 370 bifacial panels. Will use some 4x4 posts to create a shed over my pool equipment on a West facing side of the house.
5 panels.
2 apsmart rsd-d
1 apsmart rsd-s

Panels in series output goes to a
DC disconnect INSIDE the house.

(using 10awg copper wire)

From disconnect the wiring passes through the apsmart transmitter. The apsmart transmitter is connected to the sol-ark-15k pins 15 and 16. The power to the apsmart will come from a wall wart. The RSD button will be mounted EXTERNALLY right next to my existing solar disconnect switch. (connected to the sol-ark B B pins)

The 10awg wiring will feed into the MPPT1 of the sol-ark.

Thought process-
This covers- panel level shutdown. External disconnect. appropriate wire gauge.
Distances from panel to sol-ark- apprx 15 feet.

does the DC disconnect also need to be EXTERNALLY mounted? or will the RSD button serve the purpose?
Any other ideas?
 
DC disconnect is fine inside in most jurisdictions. Technically you don't need the RSD though since the panels are not on the roof of your home, at least as I understand it.
