Here is my setup. I am running an 8k Deye. I have two of them but am only using one right now. The battery box is from Midnight solar. Each battery runs with the Pytes 4 AWG long cables to its own 100 AMP DC breaker from Midnite, those then run to a bus bar and from bus bar to 250 AMP DC breaker from Midnite with 4/0 Cable and from 250 Amp breaker with 4/0 to inverter (photo shows smaller cable, but I have changed it). This is an extra 250 Amp breaker for second inverter when I decide to use it. This is similar to what Ray did here:
On another note, take a look at David's video he just released.
I think minute 17 is illustrating some of the issue you are having. I realized you swapped the battery positions, but I still think a bus bar setup is going to fix your issues.
