Question on battery monitor for my solar setup.

Hey all, have a quick question. I bought this battery monitor on Amazon. The display panel is wireless and just powered by USB so I went for it since it gives me a lot of options for mounting.

DROK Multimeter Displayhttps://www.amazon.com/dp/B01M5CWR2P/ref=sr_ph_1?ie=UTF8&qid=1490893574&sr=sr-1&keywords=drok

I'm not really sure how I should wire this up. Right now I have 2x160w panels going to my controller in the front storage bay, then the controller going directly to my batteries in the front A-frame.

I believe this is the proper wiring diagram, but unsure of how I should actually go about this. Is my battery the power supply and the load the charge controller? I usually have no issues with this stuff but for some reason this is stumping me. Any insight is greatly appreciated!

  • I looks to me like it installs like any other meter, just before the final ground connection to the battery bank.

    -top left large bolt to the battery negative terminal
    -top right large bolt to to negative of all other loads, you may need a bus bar instead of putting all grounds on that 1 terminal
    -small top left screw terminal to battery positive, it requires a small amount of power to operate.
    - no idea on the jumper wire though

    you have to run everything through the shunt or it won't be able to measure everything and won't be accurate.

    maybe someone that has one will come along to verify
  • Is that picture the only installation instruction?

    I just installed the Victron unit (which is amazing since it's bluetooth to your smartphone) and it also required installation of a shunt as you pictured above.

    You simply need the negative from the battery going thru the shunt (your picture) to the coach. And yes, "power supply" is your battery. The "load" is not your charge controller.. it's the entire coach. I'm not sure what the extra + connection is for.

    The meter will then communicate with the shunt to know exactly what's going in and out of the battery.
