I have 4 wall mount batteries and 2 FB21 inverters. Page 25 of the battery manuals show this in a symmetric configuration, battery-battery& inverter-battery&inverter - battery. I want to know if it matters if I have the inverters over the left two batteries connecting to the batteries directly under them making the left most set the main battery and inverter? So battery&inverter-battery& inverter-battery-battery. Will it cause problems with the far battery or with the first/ inverter?
