Solar Requirements - Confirmation
I'm taking a 3 month mountain biking trip through British Columbia this summer. Most of the time will be spent camping at National/Provincial parks without access to electric. When I really break it d...

I wonder if that is an "extra" circuit that would account for the somewhat lower efficiency of the converter as mentioned earlier. (which is trivial compared with the big gain from PF correction)
Seems just one factor combining efficiency and the PF could simplify things. I mean why split up not handling what's coming in well with what's going out is less than what's coming in. Bottom line could be one line. Two in...one out...or whatever.
You are allowed to think of it any way you like! :)
That Xantrex white paper also uses "efficiency" for how much of the supplied power gets used, so a higher PF means it is more "efficient" that way. Converter efficiency is after that-- watts out/watts in.
Solar controller efficiency is the same thing when you do the buck converter 12-12 vs 24-12 etc., where 12-12 is more efficient. Watts out/watts in.
With solar controllers instead of PF happening before the watts in part, you have how much of the panel's rated power arrives at the controller. There is power loss due to heat, and line loss from panel to controller. Even before that there is "panel efficiency" for its output vs area.
