There is a skin effect at high voltages and high frequencies. But we are talking low voltage DC, so it is all about cross sectional surface area. And the more surface area then the less resistance. To get the same surface area as the bus bar, the stranded wire would have to be larger due to all the space between each round strand.
I have a battery bank using a copper bar (electrical spec from mcmaster) threaded thru my battery posts on an AGM battery bank. Responders tell me to use cables instead. They say stranded wire conducts electricity better than solid copper? What do you think? The specs say larger AWG sizes are lower in ohms resistance.

Your sugestions would be appreciated.
