He will never see 20 amps of solar.
Amps will only go one way if the inverter is drawing more than the solar panels are producing.
I think he is using battery voltage sense wires.

If he has the 80amp PD going as well as say 20 amps of solar, he would equal his 100 amp fuse on that path. If he passed the solar along the inverter wires it would only add up to the solar amps on that 80 amp fuse there.
I am not clear on what happens if the amps are opposing direction on the same wire. What would the solar controller think is going on if it is trying to pass 20 amps to the battery along a wire that had 10 amps coming the other way to the inverter?
