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 not read the whole thread.
I installed two meters about the same as Mr Wizard got. I had a 200A one and a smaller one, 30 or 50A, I can't recall exactly. One for the whole house and one for the solar by itself.
After using them dry camping a few weeks last winter, I feel they are not all that accurate at measuring amps, unless you are in their sweet spot for current draw. I mean, they are "okay", barely. They will give you a rough idea of what you are charging or drawing.
They do net out the current if you are charging and discharging through the same shunt.
The controls are not super friendly. On one hand, it's a great little piece of tech for cheap, and a lot better than nothing. On the other hand, I can't recommend it. I think if you want good data and ease of use, spend more money.
