Well,
After some testing it turns out that one of my new panels are defective. I was doing some testing in full sun today and maxing out around 15 amps. Doing some testing on the roof I determined that one panel, although it registered 19 volts, is not putting out any amps. I tested all the panels with a test of test cables straight from the panel connection to the combiner box.
It would have been more convenient to discover this before mounting them to the roof. Due to nature of how the Renogy brackets attached (bottom of the panel frame) I think I'll have to pry the VHB tape up to remove it.
