Conduit for 60V DC

[JasonG2020]

Hello all, I have to run 4/0 wire through a brick wall from my battery bank to an outdoor inverter. The wire will carry a max of 60V. Can I use Schedule 80 PVC conduit, or is EMT or some other type required? The inverter doesn't have much ingress space for a single two-inch conduit. Can I use two one-inch conduit lines from a junction box on the outside of the brick to run each wire to the inverter, or is a single run required? Photos for context.

Run pvc outside with stub inside for a box. Box to flexable steel conduit or conduit.

PVC is OK.

NEC 300.3(B) would require both conductors to be in the same conduit unless you take some unusual measures, see NEC 300.3(B)(3).
