Reading this thread makes me wonder what "floating" batteries means. I thought it meant maintaining some particualar voltage on the batteries at all times after they have been fully charged using whatever method.
I believe you have it correct. To float means to hold at a static SOC. A float-charge would invoke a slightly higher Voltage.

It is 2:39PM CDST in OKC and I just checked and my 48F temperature AGM is being floated at 14.24V by the MS TS 45 PWM solar controller.
That it is floating means that the solar controller has completed its daily Bulk and Abs stages. Generally Abs Voltage is ~1V higher than float. My bank gets goosed daily.
In this situation your 13.8V float would be too low for me.
Do you have temp coefficient specs for your batteries?
