I have a 2000 watt Renogy inverter.( bought bigger to allow to grow system)
What size wire should i use to go from batteries to inverter? The cables supplied will not be long enough. Total length will be about 8 feet. Also what size fuse is recommended for this?

I used 4awg on my system. I'm sure someone will post a chart of what is recommended..... Bigger is always better....

DC current REALLY doesn't like to travel, especially not 2000 watts worth. The inverter should be within a few feet of the battery even if that means you need to rethink your configuration. Otherwise the inverter will never be able to deliver the rated power and you'll suffer voltage losses as you don't get there. If that is not possible, you'll be spending some money for thick copper cables. #0 cables might not even be thick enough without doubling them up.
That being said, AC voltage doesn't mind a longer travel. That's why Edison had to admit defeat and use Nikola's AC solution.
