I have a 10kw generator that I have wired to an inverter. I am curious about how important it is to keep consistent on wire size and type. I know the two leads need to be the same but how important is it to keep the neutral the same size. Also what if the two leads were copper and the neutral and ground were aluminum.

Relatively important. A neutral is the return path of power, so yes it’s important. Copper and aluminum have different characteristics. So if your inverter is sensitive to that, it will be a issue. I would just use all copper. Not cheap I know..
