Running 24v and 12v Solar in parallel???
Just curious what would happen if one was to run two systems, side by side (i.e; in parallel)... 12v/pwm and 24v/mppt? In particular, how would the two charge controllers handle things? Would t...

I'll be traveling past Markham twice, this Friday, and am considering picking up a pair of those 24v panels, on the way back.
I originally went with 12v panels, planning on a portable pwm set-up, but changed my mind, given the circumstances in which I boondock ~ 6 months a year... it's one thing to overnight at a walmart or casino, come weekends, but another to "hide" in say downtown Toronto, 4 nights a week, where there's a city wide ban on overnight parking in any plaza; including walmarts. :(
But I'm continually adding to my nightly "hiding" places... many of which are all about hiding in plain sight. :) Being stealth-like in a not-so-rv-friendly society has its challenges. In fact, I recently discovered I may have a (so-called) family member taking it upon themself to get me kicked out of parking spots that I had property-manager-level permission to park in. Nice, eh?
Anyhoo, I have just enough room for 4 panels, flat... so working out a tilt/twirl system for at least two of them is a little more challenging than it was when going with only 2 panels... but, then again, may not be needed if going from 280w to 780w, anyway. (maybe a tilt only set-up???)
Either way, as you point out, the 30a tracer would not handle the amps, on its own, so its either a bigger mppt, or a parallel system. All I need for a paralleled set-up is the 24v panels and some more cabling.
