What I got from Schneider electric Solar systems (sister company to Xantrex) the 10 gauge will support 30 Amps of DC voltage @ 95% efficiency vs. 6 gauge at 98% the 4 gauge was not on Schneider's list but I cannot imagine anything more than the last 2 % that's missing from the numbers if my math is right?
If this is reference then the problem of say a cloudy day could amount to 10 to 20 times (50%+) the issue of that of wire gauge so I was wondering if I am missing another reason that I should not use the 10 gauge wire other then this loss?
Thanks for your time and knowledge with this!
Wish I could give a great fantastic answer, but I can't. I am gong on the information that John and several other folks with knowledge on solar re: the 10 gauge being to light. A great one to ask (on this site) is Rodeworthy he's probably up on this as much as anyone..Wish I could be more help.
