Thanks, I copied this layout from a couple of the installations I referenced earlier in this thread. If you go to those, one of them really lays out what everything is needed for.
Basically the two lugs in the upper right are there to have the solar wires terminated from where they come from the roof. You can follow the red feed from there into the left side of the fused disconnect box I used. That will fuse the solar hot from the roof going into the Solar controller red in. The red out from the solar control goes back through the other side of the fused disconnect box to protect the controller from the battery feed. The blacks just go into the controller and are fed right back out to the shunt. That is there to hook the meter up to. There is one other photo earlier in the thread where you can probably make out the rest of the cables in place. The fuses are actually in a holder that just goes into the fused disconnect.
