Well progress is slow... but getting closer to hooking up the first new pole mounted array to the CC. The power has to cross a 15 foot driveway ( entry to exit) before it reaches the combiner & CC.

I had planned on using a conduit for each of 8 arrays but I did not want to place them underground for various reasons at this time so I started thinking about putting the conduit inside a larger pipe ( 3 - 4 ") or plastic culvert (12") for added protection from crushing and ease of adding another conduit later.

What are the issues of multiple conduits inside another 'pipe' ? Are there maximum numbers of multiple conduits?

    DANG !!!
    Nada !!
    I run a 20"' (big pipe for main ) , please lets use the real measurement "ISO" standards . 50 Cm pipe that has insulated pipes & solar & micro cables plus all in one large pipe.
    OWB to house , plus all around .. You make your own "pipes / conduits" and section them . Please the NEC/codes are NOT red or even knowing of anything thats not GRID.
    Build your own , pipes sealed within pipes and there sizes, DON'T go small , Large or the shovel / back pain will teach. do it code wise +++ ..

    NADA = great
    Planned on using 1 or 1 1/2" PVC, glued together.
    OWB ???
    'sealed within pipes' = glued?
    Large, concur.
    back pain? > that is why there are backhoes...
