Aluminum wire got its bad name during the era when it was use in 15 and
20 amp circuits, with #12 and #10 wire. That stuff is a
nightmare. As an electrician that has cleaned up some of the
messes, I can supply ample horror stories. <br><br>
#2 and larger sizes of AL work fine. It is important to use
antioxidant on the connections. Separate copper wire from aluminum
using a listed splicing device. <br><br>
Aluminum wire will turn to white powder in an underground cable where the
insulation has been breached. This is true for DC or AC. <br><br>

<blockquote type=cite class=cite cite="">I have used AL wire in DC
circuits for 30 years and have never had a problem. If you carefully
follow the protocols for working with AL you should have the same
experience. As pointed out the cost difference can be staggering. I'm
designing an o-t-g 3kW PV system now that has this array 1300' from the
batteries, AL is the only reasonable answer.<br><br>
