50FT cable run from 80w kyocera panel, bad?
Hey all,

I am assembling a little off grid system for my cabin and was wondering if a 50+/- foot run of 10awg from my Kyocera KC85 will result in too much voltage loss/drop.  Reason being that the panel is to mount on the storage shed roof in the sun and I am placing the batteries/charge controller/inverter/etc in another out building where the main panel is.  Thanks for the help!

110 watt 9.17 amps of 10 gauge should be able to go around 65 feet according to my chart so It looks pretty good

Thanks Rene, I found another chart that stated I should use 8ga for my run, but we'll see how much voltage drop I get with 10 first I think...

10awg will do 24 feet at 2% voltage drop.  8awg will do 38 feet at 2% voltage drop.  6awg will do 60ft at 2% voltage drop.

at 5% voltage drop,

10awg will do 60ft, 8awg will do 79ft.

hope that helps,
