    Joining RV and Trailer Systems

    i have a trailer with a dual battery, 400W 12v system and an RV with a dual battery 12v unknown W system (3 panels). They both have their own controllers.

    They both have inverters, the RV at 400W and the trailer at 2000W. I plan to swap the RVs 400w to the

    When I am parked I would like to join the systems at the DC battery level. So technically the inverters are a moot point.

    Primarily it would be to take the RV as master. I would expect both systems to be equally healthy and balanced at roughly the same battery levels.

    I realize there could be issues having dual controllers, but that is the configuration I have as each is to be standalone systems.

    Please advise any technical issues I may have and suggest the proper mechanical connection apparatus I should use.

    thank you,

    Mike

    Lonestarrpm,
    This is happening a lot lately. Try again or wait for the Moderators help. Why it cuts off where it does makes no sense but there's something about certain text that is causing the problem.
    I see this is your first post. Hang in there. It'll get fixed.

      If it matters -- I entered it twice from my iPhone -- the last edit was via laptop.

        I found this which suggest (despite not having this controller -- or the same controller for each setup, I should be ok -- or at least tolerable)

        So now I'm just looking for mechanical/electrical hook up suggestions...

        I'm also in search of a pair of system meters

          You will need some sort of DC connector for both - & + cables, something like a Anderson Connector ( used on cop cars & tow trucks on the grill for jumper cables )
          The wire gauge will need to be large enough to reduce voltage drop, something like 4ga , maybe 6ga if you are lucky.
