Battery configuration

With 20' between the Sol-Arks and the batteries, would I be better off with individual cables to the batteries (A) or a heavier gage wire between and a junction box near the Sol-Arks (B)?

It really comes down to cost.

Since I don't know what Sol-ark, I used 5kW for each inverter.

For A:

2awg x2 for 20' @ 200A/51.2 = 1.22% losses

For B:
