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 ...

My fool-proof way of getting expected AH or amps based on some measurements I made last year, is that 460w should get you 460/130 x 8.2 = 29amps pointed with PWM. If you believe the MPPT guys, add 10% = 3 plus the 29 = 32a
Just when or how long you get those max expected amps "depends" on your set-up, etc.
In cases where you are far enough north of 23N that flat is less than tilted, by "enough" then that could get you below 30 from that 32 I figured.
490w would be 490/130 x 8.2 = 31 with just PWM. Add 10% for MPPT= 34a.
