Calling on Solar Techies
I have been thinking of going solar for some time and decided to pull the plug. My wants are a 400 to 500 watt system. I have four 12 volt batteries with 340ah. I am not planning on changing b...

Ok, what specifically do you mean by 'uses PWM when in Float and Absorb'?
As I have explained numerous times now - it is clearly not doing the same thing as a PWM controller when in float and absorb. When necessary it has the ability to boost the current in float and absorb, which a PWM controller by definition cannot do.
I just walked out and turned the fans on in my camper (5A load), it is afternoon, the Victron MPPT 20/100 is in float mode, solar panel is producing 18.5V at 4.0A, charge controller is outputing 13.4V (float for my LiFePO4) at 5.4A (0.5A to the battery, 4.9A to the fans). Right now my MPPT controller is producing ~30% more power in float than a PWM controller could.
I don't know how else to explain this to you.
