What you could do: (naming Batteries b1-b6): one wire: b1-b2-b3-b4-b5-b6-inverter, and the other inverter-1-2-3-4-5-6 .

could make a huge difference as far as getting the most cycles out of my new battery bank.  check this out-

I mean I think I know how I would do it... just getting other input from y'all.  thanks!

I would probably also run a wire from each battery pole to the inverter to keep the cable size manageable. (AWG 10 instead of 000)

yeah but im also going to the load on my charge controller to a fuse box for 12v applications + the inverter (straight off batteries)

12 volt, 2000w continuous, 4000w peak pure sine inverter

i know how to wire in parallel.  i want the batteries balanced, as in this diagram, but with 6 batteries

well, like the title says, I have 6 new 12v AGM lead sealed batteries.  75aH each.  Going to wire in parallel.  

I have seen many wiring schematics but they usually show 2 or 4.  If they have more than that, it's usually a series parallel hybrid.

I understand that the + and - mains coming off the ends of the parallel battery bank need to be the same length, but what about the parallel wiring to balance 6 in parallel?

I get the concept, just not sure how to do with 6.

And also, what would be the biggest 0/0 and what would be the smallest gauge I would want to use for the parallel bank?  

Does the overall length of + and - between the batteries need to be the same exact amount of length too, or just the ones going to the inverter and load?

If I was guessing, I'd say I should use 2/0 gauge welding/automotive wire among the battery bank and maybe 8 gauge going to inverter and load on charge controller?

pv goes to 40a mppt renogy
battery bank as described
2000w pure sine inverter peak 4000w

I get the concept of the fuses and where to place them and what size, just need help with the 6, group 24 battery balancing configuration.  

any help is greatly appreciated!  cheers!

the wires that come with the inverter are generally garbage and too small
and what he said earlier about connecting the inverter straight to batteries.... with a fuse between.  load/breaker box goes to charger load.  and like he said earlier, those battery cables look too small.  2/0 gauge welding wire between them and maybe a 8 gauge going to inverter and fuse .... fuse maybe 30a?  also, fuse between panels and charger... 20amp.  and yeah, like he said earlier, you shoulda got maybe like a 40a mppt.  i just got a great deal on a renogy 40a advanced rover with bluetooth for $141 mppt from amazon.
