Bump.
The Sol-Ark 15k has been installed and the bottom inlet panel is very crowded. Just waiting on the battery build and wiring now.
I have three, 300+ amp-hr battery boxes that I intend to wire in parallel to connect to my Sol-Ark 15k. The Sol-Ark is located on the exterior wall of my garage, and the batteries will be situated on the interior side of the wall. I purchased the HomeGrid busbars to tie each battery input together to achieve the max 275A current transfer using 4/0 cable. My plan is:
Inverter -> 4/0 > T-class fuse -> busbar -> 2/0 -> battery breaker -> battery terminals.
My question revolves around conduit for the 4/0 to Inverter connection. What type of conduit is appropriate for use in this application to traverse the brick and connect to the Sol-Ark? The knockouts on my Sol-Ark are very full. The easiest thing for me to do would be to have separate conduit for the positive and negative cables, but I prefer one penetration for the brick. Can I have each cable feed to a single junction box, then put a single penetration behind that junction box to the interior? Or should each cable feed to a conduit outlet, then traverse the brick siding separately?
I also have a Rasberry Pi and would like to run ethernet and power through the conduit (if permissible), so it needs to be sized to accommodate both 4/0, ethernet, and DC power cable.
Also, what is the best way to terminate the 4/0 on the interior? Cutoff switch? DIN Breaker or something else? My wife is very sensitive to aesthetics so I would prefer for the connections to be organized in appearance.
