What size bus

[71naes]

I have 2 EG4 cabinets with a total of 10 @ 5.12V100Ah LiFePOWER batteries. I am connecting them to my dual inverter off-grid system.
What size bus bar is recommended?

Total charge amps or total discharge amps will determine the busbar size.
Usually its determined by the inverter/charger or all in one you have selected.
What will you use?

I have 2 out back 8048 inverters with a total of 3 100 amp charge controllers

8000 ac watts / .85 conversion factor / 48 volts low cutoff = 196.078431373 inverter amps
196.078431373 inverter amps / .8 fuse headroom = 245.098039216 fuse amps
245.098039216 fuse amps * 2 inverters = 490.196078431 busbar amps minimum.

Thanks, I am planning on a 1,000 amp bus bar. That should be sufficient.
