Not a TriMetric, but for $20 might be worth trying out...
Bayite DC 6.5V-100V Digital ammeter voltmeter Amazon suggested this for me and I'm thinking for $20 I might just give it a try. Has very good reviews too.

It is possible to do All kinds of wiring contortions
That does not mean you are going to get correct readings
If you attach to the controller output, you will read controller voltage not battery voltage at the shunt
What ever the voltage drop between controller and battery shunt is , Will alter the Watts display and voltage value displayed
But if the wire is short and thick, the differences could be small enough to not mean much
