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...

The Trimetric uses 96% (allows 4% for losses) on recharges. This is mainly till you get up to gassing voltage, then it does not try to stay even with heat losses. However, the amps are low at high SOC so the "percentage of what?" is low too, so it doesn't get far off until you do a number of cycles, then it needs a reset.
You have some idea of your bank's capacity, so when it gets to, eg, est 50% SOC by "morning voltage" being 12.1 (with 6s) you can see if you are close to half the AH as a cross-check. Anytime, if your "no load" (parasites only) voltage and AH figures don't match, you know the AHs need a reset or you have a load running you didn't know about.
(Outside lights left on, converter on inverter, tank heaters, etc, etc :( )
It is all "close enough" for camping- not meant to be a science lab. The situation would be much better if it had its volts to two decimal places, but you need a shunt that can go with high amps so that means one decimal place on the volts. You can use a voltmeter if you need more accuracy on voltage.
