I referred a friend to this package just the other day, I thought it was a good buy---
Renogy 200w Solar kit on AmazonComes with a Renogy MPPT controller that can handle 100v VOC
2 Renogy 100w panels
All cables and mounts
$449
Or, if you think you may want to add more panels later, the same listing has an option to upgrade to a 400w MPPT controller for $70 more.
Given what you're describing about your solar pre-wiring, I would wire the panels in series. I have 4 panels on my trailer wired in both series and parallel because I had to. The controller is limited to 150voc, and each panel I have is 48voc, so I'm running 96voc per pair of panels
