Looking back a lot of years I remember running 24 vdc 150' with [4] 4/0 THHN cu for an array feeders for about 1.5K of 75 watt PV modules. Just the lay out could have crippled you before lunch.
Perspective and forward progress is a wonderful thing. #6 ain't diddely we would have begged for the opportunity for pulling #6. Opps the grey hair is sticking out here......

I looking at a job and thinking about replacing an MX-60 with a 700 foot pipe run to the array wired with #6 thhn!!!! My understanding is that the further away you get from the battery voltage, the greater the efficiency loss is within the unit. Outback gives the curve to show the loss of output at higher voltages, but searching Schneider's site I can't find anything close. It's either going to be this, or tying a grid-tied inverter through the Outback output, but doing that would only get me single stage charging. Has anyone watched these controllers over time? Monitored its output?
