If you planning to get full 12KW output from 48V batteries, it can draw as much as 250A so if you using 100Ah rack batteries you need 3 batteries per inverter (via a bus bar). I am connecting mine to Eco-Worthy's 48V 280Ah batteries which in theory I just need 1 battery per inverter via a 4/0 wire that can carry 250A, but it will drain quickly, and E-W handicaps this 280Ah battery with 200A connectors, 2 AWG wires and 200 Amp BMS (no way I can connect a 4/0 wire to it). So I will need to connect 2 of these 280Ah batteries per inverter also via a bus bar.
Only other notable issue is tightness of connecting 6 AWG wires to the AC OUT. I am using high quality flexible SOOW copper wires but Romex might be too stiff and unyielding to fit into terminal block and tight spaces.
If all these sounds overwhelming, it is, and each connection need to be torque'd to spec, every wire and connection part needs to be high quality, and you still need high quality and not cheap breakers/fuses to protect wires and components.
So if I did not need 24KW (I am doing 2 of these inverters) and just need 12KW, I would look hard at 2x Anker F3800 with Smart Home Panel which can do 12KW and 240V, or the new Delta Pro Ultra X which can do 12/24/36KW but gets pricey.
