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.

NOT a display light switch
if power is shut OFF
the meter shuts down and looses all data
and Resets-default back to OEM condition
12ampHr capacity with 6ampHrs charge
NO it does not track anything if power is shut off
its a leave it on OR start all over again situation with this meter
having Solar its a NO brainer, leave it on
i think the idea ? of external power is so you can power it from low voltage DC, while monitoring a high voltage DC system
