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?
Sure. There's no appreciable load on the voltage sense lines (by design), so wiring multiple meters in parallel to them is no problem. You have a very low impedance source feeding a very high impedance load. What you want to avoid is powering anything from the voltage sense lines; they're for measurement, not power. The main goal is to avoid voltage drop in the sense wires, which is accomplished by having no appreciable current flowing through them.
Current shunt connections have similar properties, too; you can put many ammeters on a single shunt without problems.
