CaTraveler,

I thought you use Voc when talking series and mppt?

Voc is used to make sure that the controller hardware can tolerate that much voltage should it occur in some low light or other situation. Voc means "open circuit" and that means no amps or power.

Otherwise it's Imp and Vmp (maximum power) for MPPT for either series or parallel panels.
