OK so "don't sweat the small stuff" is what I'm hearing. Now what about the load, if I series the two 100 watt panels and get 24+ volts, will the MPPT then convert the excess voltage to amperage (supposed to) and will any "load" voltage be 12 ish volts? That's the main question, so that I can take advantage of any load option...

I don't power anything off the load terminals. I think those were there for unattended lighted signage. All my loads are connected to the battery through a fused distribution center.
Yes, MPPT controllers do convert excess voltage into amperage unlike a PWM that just throws excess voltage away as heat. My system is 400 watts of panels in a series/parallel configuration. 200 hundred watts in series and 200 watts in series that are then paralleled and fed to the MPPT controller. 200 watts affixed to the roof and 200 watts as portable for when I park in the shade or as it now in the desert with a low sun angle.
