[RE-wrenches] Megawatt System - Combiner Output Wiring

We're in the process of designing our first >1MW system. It will include
inverter output combiner panels (potential aggregate current >700A) located
approx 100' from the system disconnects.

Since we have never previously dealt with wires this big (2 sets of
paralleled 500 mcm?) we are thinking that direct burial (aluminum)
conductors might be a good option - any suggestions? What wiring method do
others use for this type of *large ampacity* AC circuit? UF? USE? USE-2?
Other?..
