The southwire voltage drop calculator is different from the Alte store chart
For a 6000w inverter that is 48v = 125 amps.
Southwire says 2/0 awg for 4 ft at 125 amps -

Also says 2/0 https://baymarinesupply.com/bosns_corner_wire_sized
Alte says 4/0 for a lower wattage of 5500

Why the difference?
If you scroll down to the "input parameters" section on the southwire link it tells you a recommended wire size and the voltage drop
Also, I'm assuming use the same wire from the controller to the batteries since the voltage will be "48" volts and not my panel voltage
