 Since the panels make more power at higher voltages((up to Vmp)) cranking up Vabs and Vfloat to higher-but-still-sane levels will result in more power being harvested.
-Using the above panel as an example, Vabs of 14.7v will yield 3.5% more power than a Vabs of 14.1v.  Vfloat of 13.8v will yield 4.5% more power than a Vfloat of 13.2v. \

-Note:  consult the battery manufacturer's recommendations for the actual maximum voltages.  Controller presets often are set low by the factory since they don't know what battery you will use it with.
