Hi #4 wire is not really rated for 80 amps, so I would not fuse it at 80.
70 Amps Rated ampacity of selected conductor
0.2957 Ohms Resistance (Ohms per 1000 feet)
0.048 Ohms Reactance (Ohms per 1000 feet)
0.36 volts maximum allowable voltage drop at 3%
0.9 Power Factor
It's rated for 70A at 60 C, 85A at 75 C, and 95A at 90 C; all in conduit.
In a residential service application it can be rated 100 amps.
Since I would assume this is a "free air" installation it's actually rated at 105A at 60 C, 125A at 75 C, and 140A at 90 C.
I think an 80A fuse sounds like a good fit.
