Optimum Manual Charging Scheme?
I'm looking for a general description of an "optimum" charging cycle for a 100ah - 160ah AGM battery bank. Let's say that I'm using my Meanwell power supply, adjustable 15v 13.4A. Let's imagine ...

IMHO 14.8 is a little "ripe" for an AGM. Myself I would first see how 14.4 volts does. The PSU cannot reach absorbsion voltage right off the bat. Not with a 100 ampere hour battery discharged to 50%. Remember this is a 33 amp potential (smaller unit).
This is where an AMP HOUR METER is very handy. And this is where a kWh meter would make figuring this out a snap. Total up minus amp hours. Recharge with 115% of that figure. Print a chart in 5 amp hour increments and post it next to the meter.
The final 5% recharging gets balky. You can tweak voltage up incrementally and see through live example (time) if this -dramatically- reduces generator run time.
Verify the validity of your selected CHARGE EFFICIENCY FACTOR value of (115%) by doing a 24 hours at rest voltage check. Be sure to compensate for temperature. CEF is slightly different manufacturer to manufacturer.
Once you have this tweaked it's a done deal until the battery ages or a glacier comes through your back door.
