Planning out my install for the above two components. The Manual for the Orion calls for 10mm2 wire (<2m) and the MPPT calls for 6mm2 10AWG. When I look at Ancor's site for marine wire, 10AWG appears to be 5.26mm2 with a max amps of 60A. There is no 10mm2 wire so my choices are 6AWG (13.3mm2; 120A) or 8AWG (8.37mm2 and 80A) the 8AWG seems to be more than what the Orion could possibly output; though on the input battery side, the alternator could in theory output 120A.
1. Can the orion even accept 6AWG wire as into the input?
2. Would it be acceptable to use 8AWG on the Output side (with appropriate fusing)?
Am I misunderstanding the recommended cabling?
