hi mr. jacobson,
congratulations on getting your system ready for first light! this is that cabin system in maine?
i'm sure you have seen the battle cry of "keep the parallel strings to two or three max" and good advice it is.
when we start to get into many parallel strings balance issues become a huge factor* and can doom a system to failure if we try to set it up in a conventional way.
your system with "only" four strings and that exeltech 24v 1100w inverter should do just fine with the traditional series/parallel connections at the bank then up through a breaker** to the inverter. we will only be pulling about 50amps full throttle. i question the recommendation by exeltech on that 6awg wire. you won't regret going oversize with all the battery connections and inverter wiring here.
also, i would shuffle the batteries in the bank once a year or so with this setup.
if this is to be our final system size with no other loads, all grouped together in the same area and i had to pick a wire size i might go with 2awg for all battery and inverter wiring.
*some info about problems running parallel strings and what we can do to correct for it.

a nice setup and writeup here.

kind regards, dave
edit: method 4 on that smartgauge link looks like a winner here. this is a new addition since last i looked.
