Tri-Metric programming help
I just installed a tri-metric 2025 in the outback 230rs last night and now need help with the programing values of P1, P2, and P3. The battery that came with the OB is a Crown MAR-500: MCA 550 20 A...

Just for info, you can get very good value from your Trimetric without ever setting the "three things."
I have an idea of my battery bank's capacity, which is always changing due to temperature, which is always changing. So IMO the Trimetric idea of "percentage charged" is totally bogus.
Nevertheless, right out of the box, it can do accumulated AHs, amps, and volts, which is all I ever need.
For solar, be aware you need to kill the "auto reset" of AH as suggested in the instructions, or it will reset every time it gets dark.
You can kick off with battery full according to its SG, and reset the AH. Then get down to 12.2v for your "morning voltage," and note the minus AH you are at. Call that 50% of capacity, so now you know what the full AH capacity is at that temp. Recharge by whatever means you have and carry on.
If you ever get recharged back to zero AH or more, confirm by SG, and reset the AH to zero and carry on. You will need to reset the AH to zero every so often. Just how it is.
If you think that is all nuts, read the Trimetric instructions of how to under-shoot your actual capacity, so the battery never gets to "true full" before the Tri says it is full after using your phony "three things." :)
I love my Trimetric, but it works for me; I don't work for it!
