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.

okay
i got mine connected today
the mounting is only temporary, need to tidy up the inside wiring
and i need to finish the calibration
input values for the battery ampHr capacity, and present 'amphrs charge' which sets the percent of charge
temporarily i input 300amphrs charge, just so i could let it count down from there and show me my overnight useage
the good
Shows .. battery volts, amp flow, watts being used/charged, percent of charge,
ampHRS count up and down, and percent of charge number is amphrs count versus battery capacity number
the bad
does not differentiate between plus/minus amps charge/discharge (No minus sign indicator)
it only shows a positive number, even when discharging
really not a problem, because there is a charge LED/light that is on when its positive flow aka charging, and NOT on when discharging,
So.. Instead of a minute sign indicator it has a plus light indicator
tomorrow i want to do ampflow check using my clamp on meter and the new power meter and calibrate it , IF the difference is not close
the 100amp model would have been closer to my avg use model
BUT several time a month i use the BIG MW and its a Whopper, 1150 cooking Watts, 1685 input Watts approximately 140 amps into the inverter
and i didn't want to risk damaging shunt with over amps
so i got the 200amp model
