Hello!
I'm about to install a system folks here helped me suss out last year. I'm pretty much all set except for the wiring and connectors. Here are the relevant variables at play:
3 x 265W SunEdison MEMC-P265AMA pannels wired in series, each one contributing:
35A Victron BlueSolar 150/35 MPPT charge controller
2 x 105AH AGM batteries wired in series for 24v
100' distance between panels and charge controller
The big question, of course, is what gauge wire should I use to get from the panels to the controller. If I'm using the voltage drop calculator correctly, it seems that 10AGW or better works. Should I spend the extra money and go with 8AGW or even 6AGW, or are the benefits too marginal to worry about? I'm doing a direct burial and that seems to be tougher to source that in 100' continuous length for 6AGW.
Thanks!
Steve
