PD or Iota for my upgrade?

You had to be down to more like 60% SOC.

Seeing from my graphs of this that at 80a tapering would start at about 80% (ie at 368AH) going back an hour (80AH) start would have been at 288AH which is 288/460 = 63% SOC.

Hmmm.... The TriMetric never indicated anything in the 60's. My recollection was that it was 80A for about an hour, but it may have been 80A for less than an hour.

Your "morning voltage" (light load before making coffee etc--and before "solar wake-up" jacks up the voltage) would have been 12.2/12.3 which would have been another indicator that true SOC before the recharge was near 60%.

I do recall checking voltage each morning. It was closer to 12.7 than 12.2.

I like to compare my "morning voltage" every day with the AH used up as shown on the Trimetric to see if they are both telling the same story for estimated SOC.

I wasn't focusing on battery charging while on vacation, but my old system was to monitor voltage, so I did watch voltage reasonably closely.

If you were indeed running 60-90s, then now is the time to do some equalizing /overcharging to get the batteries back to "baseline, as new SG" or they will never recover to 460AH ready for the next trip.

Good idea. I'll check the current SG and compare to the numbers I had when I bought the batteries and after I'd equalized them.

I do wonder about the difference between daily charging them to 14.8 as I'm doing with the modified system versus daily charging to only 14.4. It certainly seems like 14.4 is quite low in view of the significant increase in charge current when I switch in the 14.8 setting.
