Guys just a couple of questions, I'm looking at setting up my first system here's what I'm looking at, three 250W panels = 32 amps? Six 6v gulf cart batterys = 12v 585A probably a morningstar MPPT controller, now first question, if I'm reading the wire chart right to get the 750w 32A 50 feet to batterys I'll need #1 wire for 12v #4 wire for 24v is that right? Next question, if I go 24v can I knock it down to 12v for appliances that don't take 24v?
