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.

setting the current amount of amp hrs .. is slow
i haven't timed it, but i think the number count increases about 1amp hr every 2 seconds, so setting 400 or 500 amp hrs, as present charge/amphr count is a long time holding the button
...
No kidding. Luckily I had something to read close by.
Finally got this thing installed and working. Like the Wiz I installed it to measure net current; the shunt sits on the negative post of my battery bank.
Calibrated V and charge Amps against my Rogue mppt readings.
Checked some higher discharge Amps with my clamp-on ammeter, and they were close enough (inverter load wasn't very steady). This 100A unit might be good to +-1 amp? Very roughly comparing it to the Rogue ...
At one point I decided to reset to factory defaults and start the calibration over. But when I did, all the readings just went to 0 and stayed there. Then I temporarily removed power, and it reset and I could start over.
What a really nice unit. Love watching the current flow.
