What part of FL are you in? I just finished installing a 15Kw system on my home just about the same equipment. If you're close by I can show you how the connections are made.

This leaves the breakers in the attic where they can be more easily reset if needed, instead of under a PV module.
Run conduit down to a disconnect and paint it to match the siding
OP should check as a locking disconnect is commonly required.

Seems like I have see so many installs where the branches are just simply brought to a j box and combined with wire nuts to the circuit running to the inverter / a/c disconnect.
You can add fuses to combine or just use it to get into the attic.OutBack FP1 w/ CS6P-250P http://bit.ly/1Sg5VNHComment

Ok. So I like the idea of using A Soladeck under each array. Is there a certain type of box that I would use to combine the three branches into to make a single homer in? Is there actually any advantage to running a single Or is it just as well to run all three branch circuits and their individual grounding wires in 3/4 EMT?
thanks for all the help guys.Last edited by Tooncinator; 03-12-2019, 07:25 PM.Comment

Another thing to keep in mind, from that picture you posted. IF you're using conduit metallic all the way down to your disconnect means, that green ground wire isn't needed since the conduit body acts as the EGC then you just ground your conduit to your ground bar. IF you're using romex inside the attic to skip the need for conduit, then you WILL need that EGC.Comment
