How large is your battery bank?
Unless you are over 220 amps it will be harder to hit bulk mode until batteries are depleted somewhat. For two 6 volt batteries or less the 45 amp charger would be the correct model. My 12 year old WFCO has always hit bulk mode at about 85%soc. The first pair of T 105's lasted over 10 years.
It should be noted that the charger can output 45 amps (or more dependent on model) at 13.7 volt charging. Using a clamp -on meter would confirm this. Not seeing 14.4 volts does not always mean "bulk " charging is needed for a longer time. Don 't panic from some posts here unless you have actually seen problems with your current batteries.
