[RE-wrenches] Trimetric with Outback

[Jay]

Hi Bill

Because OB has all their shunts in parallel, no one shunt carries all of the current. 
Which assumes you are using 2 or 3 shunts for the monitoring. 

Therefore to use a trimetric you have to add a 4th shunt that carries full current.

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.

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 NET 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.
