<div dir="ltr">Bill -- I have "cooperatively attached" 2 different shunt monitoring devices to the same main (DC net -) shunt with no issues, for similar reasons (kitchen where client wanted a simple display is too far from shunts and Mate). The phrase is from the Midnite Whizbang Jr. manual, they supply a couple aluminum spacers for the other company's shunt sense wires so they don't short the WBJ board (the WBJ electronics mount on the shunt). <div><br></div><div>As long as the ring terminals for the Trimetric sense wires can still lay flat while stacked on the FNDC sense ring terminals, you should be fine. I don't see why you couldn't use conductive spacers if the ring terminal barrels interfere with each other and won't lay flat. In my client's case, a second Mate for the kitchen was over twice the cost of a Trimetric without shunt, AND he can read the Trimetric from across the room because of the good ol' LEDs, not so with a Mate 3s.</div><div><br><div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div style="margin:0px;padding:0px;border:0px;font-stretch:inherit;font-size:12pt;line-height:inherit;font-family:Calibri,Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(0,0,0)"><span style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)">Dan Fink</span></div><div style="margin:0px;padding:0px;border:0px;font-stretch:inherit;font-size:12pt;line-height:inherit;font-family:Calibri,Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(0,0,0)"><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)"><span style="font-size:12.8px">Owner, Buckville Energy Consulting LLC</span></div><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)"><span style="font-size:12.8px">NABCEP Certified PV System Inspector</span></div><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)">NABCEP PV Associate</div><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)"><span style="font-size:12.8px;font-style:inherit;font-weight:inherit">NABCEP Registered Continuing Education Providers</span><br></div><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)"><a href="mailto:dan.fink@greendustrialtraining.com" target="_blank">d</a><a href="mailto:anbob88@gmail.com" target="_blank">anbob88@gmail.com</a></div><div style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:12.8px;line-height:inherit;font-family:Arial,Helvetica,sans-serif,serif,EmojiFont;vertical-align:baseline;color:rgb(34,34,34)">970-672-4342</div></div><br> </div></div></div></div></div></div></div></div></div></div></div><br></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Nov 22, 2020 at 10:05 PM frenergy <<a href="mailto:frenergy@psln.com">frenergy@psln.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p>Wrenchers,</p>
<p> I tried asking OB about this, no response. New
FlexPwer2 installed in customer's basement, I like to keep the
Mate with the system because the basement is my access point for
future programming, troubleshooting, etc (rather than entering the
house which many times is unoccupied)...no internet or cell
service onsite. <br>
</p>
<p> To have some system status info in the house for the
customer I would like to install a Trimetric 2030 upstairs. This
looks a bit tricky with three shunts in the DC enclosure to
monitor various in/outputs for the FNDC to function and display
info properly for the Mate. Where-o-where might the sense wire be
connected to properly measure <b>NET </b>amps flowing hither and
fro to supply the correct info for the Trimetric? The picture
should help, the two cables coming off the bottom (right side) of
shunt "B" are inverter negs.<br>
