 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. ​ 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 too low by the factory since they don't know what battery you will use it with. Better safe than sorry, say their lawyers. ​
