For my array power & grounding drop, array to pole combiner, I use #6 or #8-SOWA cord with [Chinese fingers] strain relief.

The cyclical motion will slowly work away at coarse cables. I've even seen solid #6 break off on just a tilt adjustable array. I now use a braided ground strap at least for the rack to pole ground connection. This is the same strap that is used to ground generators and other moving electrical equipment. https://www.delcity.net/store/Ground-Straps/p_818655.h_818654 I isolate it at the connection to the aluminum with a sandwich of Stainless fender washers and a 1/4" bolt with toothed lock washer to bite into the AL, or it also works well folded in ground Lugs and buss bars. You can open up the weave of the braided copper in the middle to get the 1/4" bolt through. I've checked these years later: no corrosion, wire not broken off at the connector.
