460 watt solar setup: wire sizes?
I want to change out my old 50 watt panel and 10 amp controller with at least one and hopefully two 230 watt 24 volt panels and whatever controller would be best. Right now the roof on my fifth wheel ...

I would guess there are several of us with over 500 watts of solar PV power. Also many using #10 awg wire. Done properly it works great.
My system consists of a 550 watt array (Voc about 45 volts) with about a 15ft run of flexible #10 wire (30ft total length) to a 60amp controller and 6ft of #4 wire to the battery bank. I regularly see a bit more than 40 amps being supplied to the loads (the battery bank itself hardly ever needs that amount of current) from the array.
