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.

Subscribed because I'm interested in a 100A version of this monitor.
Can my existing voltage sense wires for my solar charge controller be multi-purposed somehow for use with this meter?
I was thinking to take the meter's power (+-V terminals) off the heavy cables at my solar controller. They go direct to the batteries.
And V sense (Vin,GND) from the solar controller's V sense wires.
All these connections are close as the meter and controller will be right next to each other.
That only leaves a single twisted pair to the shunt from the Meter's isns & agnd
