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...

If I simply added an additional 12v/100w panel, in parallel, the solar30 would be pushed to it's 80% limit, at 380w/12v... as that could potentially yield 24a (2x 9a/140w + 6a/100w).. and that would only add about 36% more power, (100w/280w). The tracer 30a mppt would see less than 8a in, but over 27a out, potentially, so again, pushing the controller's limit, all for only a 36% increase.
Two systems, paralleled would net me a 178% increase in power, (500w/280w), for the cost of two 24v panels and some 10awg cabling.
All said and done, less than $1100 u.s. for 780w... so say $1.40/watt u.s., for the two systems... (one system would be less, of course). As it is, I'm into about $1.80/watt u.s. for the 12v/pwm system, alone. ($500/280w)
So I'm actually saving money, not spending it! (I wish... :))
