I've just come across this statement in a user manual for a small inverter product:
"Do not use aluminum. It has about 1/3 more resistance than copper cable of the same size, and it is difficult to make good, low-resistance connections to aluminum wire" I think both statements are wrong. Science Data Book by Oliver&Boyd, lists resistivity of aluminum at about 1.5X that of copper. And, I don't see why electrical connections would be less reliable using aluminum, although, I do remember household wiring in the USA was done with Al some years ago with questionable success.
