If your electrical wires (the copper gauge) are not large enough or if the cable is longer than needed, then the resistance is higher resulting in less watts going to either your battery bank or the grid.

I assume you have a 48v inverter. I like to keep the precharge current down to a couple amps so if we assume the max battery voltage is 60v, a 30 ohm resistor is about right.
