Another question on Converter sizes
There is another active thread regarding converter sizes, but I get lost in the wealth of detail offered here. I have a simple question: I have a PD 9200 , 45 amp converter, two Trojan T105 batteries ...

I dont recall seeing my voltage over 13.6 volts. I have a charge pendant on order so Ii will be able to force it into boost mode.
Is that measured at the batteries? If so, it may be well worth your time to check the connections between the converter and the batteries (and maybe upgrade the wire size). A not great connection can cause a noticeable voltage drop at high currents.
The PD converters do have a tendency to not quite give full voltage at high charge currents; they are a little power limited. Indeed, the specifications list the "full load output voltage" simply as >12.6V. (I would guess that is the worst-case with the minimum specified line input voltage of 105V, and they may be able to do a little better with a better supply.) As the current tapers down, the voltage rises up to the setpoint voltage.
If you actually have a PD 9100 series converter without the (optional for that model) charge wizard, the output voltage setpoint will be fixed at 13.6V all the time.
