Is any type of 4/0 al easier to work with than another?

[GetLitSolar]

Connecting a solar inverter to a 200 amp disconnect, my electrician installed, in the near future and quickly realizing I'm in for a wrestling match.

Unfortunately, the setup is going to require an LB to get around a corner. The conduit box at the base of the inverter has 2.5" knockouts. Total run length 10-15' but it has that 90°.

If I max the size to 2.5" on the LB, can I make this turn? Or should I size up to 3" on the LB and use reducer bushings on each end?

Is there a specific type of 4/0 wire I should be sourcing to make life easier?

Lastly, why does 4/0 ser come with a 2/0 ground? Could I omit that and just run #6 cu to the ground?

I appreciate all the help and advice. I really want to learn so please throw anything you have at me.

4/0 XHHW should not be a problem in 2". Are you trying to run 4/0 ser? IF so why?

Also why 4/0 to the inverter? What size inverter is this?

Initially I was but I selected it out of ignorance (it was cheaper and had everything I needed, right?). Since then, I've put in more research and realized I was dumb.
