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.

i have something similar {to Power Analyzer} (same thing different mfg) in my solar charge circuit
i record daily readings for Amphrs, Watt Hrs, peak watts, peak amps
reset everynight
example.. todays readings
28.95 peak amps
404.18 peak watts
1766.8 watt hrs
126.56 ampHrs
thats why i bought the new meter
i wanted power readings for the whole system useage
and total system input, this way i know how much deficit i start the day with, how much i use at night, how much recharge i get from the converter etc..
Any decent solar controller will have this feature. But it only measures input side, not output, so AH meter is needed (sometimes) for battery output side. My situation was simpler, there is no converter usually (no grid), and night draw is minimal and predictable - few AH for propane fridge and very little - milli-AH? - of LP sensor. CO and smoke detectors are on their own AA. The "deficit" is under 20% on most mornings and is filled up before noon. I only look at it next day after a very rainy day, because this is when deficit might grow a little.
