What gauge wire?
I'm going to be adding a second solar panel and need to know what gauge wire I need for 2/140w panels on a 35' run. Thanks Keith

Salvo, I can't see how that post shows the unit is MPPT. He says he was getting 8.9amps from 3-95w panels. If Isc is 6a then max expected amps in PWM would be 18a in parallel.
With those three in series amps would be 6a and 8.9a would show bucking 24-12, but are they in series? Total Voc would be about 3 x22=66 which is under the 75v limit so they could be. Did he change his panels from parallel to series or just change controllers from PWM to this unit?
Windynation also has one of these Solar30 looking things and there, it explains in the blurb somewhere it is not really MPPT IIRC. This came up when that lady (sorry, can't remember her name) was posting about her ISTR flexible panel ?? vague about it all now, and she bought one of these controllers.
