Gonna be mighty expensive. I had to buy a lot of copper wire for my solar gear. It's a lot just for a single 500ft roll of #4 stranded copper... and that's not a very large size wire.

This all needs a LOT of sober reflection... but that is something that will not happen.. fools rush in...

I have this type of 4 AWG .. it's great for making the short interconnect cables for the battery banks... imagine wiring the world even with this wire that is probably cheap compared to the larger wire that would be needed.

That is actually pretty cheap considering number 8-2 romex is over $5.00 a foot.
