The MT 50 is the remote that goes with Tracer solar controllers. (there was an earlier version ) Check out the Tracer info manuals etc for how to operate it all.

It is difficult to measure battery State Of Charge just by voltage. If you want to do it accurately get a good battery charger, disconnect the battery from all load, charge according to directions. Remove the charger and let rest for about 60 minutes. Confirm SOC with hydrometer and then check voltage.

The best SOC monitors continuously monitor all current flowing in or out of a battery via a shunt. They work under the assumption you are starting with a battery at 100% SOC when they are first connected. You should probably re-calibrate every 6 to 12 months.

A Trimetric has an "auto reset" that does not work with solar. You have to turn off the auto reset or else it will reset every day at sundown when the amps go negative.

Yes, you must recharge to full (true full, not a bogus full such as Trimetric itself describes) and reset the AH counter then. This should be quite often if doing 50-90s for a period or else when on solar doing mostly 75-95s.

If you believe the % SOC on your monitor, you probably also believe in the Tooth Fairy.

i have checked out the entire chapter, but have know idea what it all means, sure I can read it, and it may make some sense, but my lack of knowledge of 12v makes me second guess every thing I think I know.

This is what you want. Got me on the right track, and it is still valid from 2002, since they had the "new" (then) electronics that are still current.
