Under gauge wire or over length wire can cause of the inverter fuse, if the load is too much.

I'm not so sure about that. A wire under rated should not blow a fuse, it will burn the wire, not blow the fuse. A blown fuse is caused from excess amperage. If, let's say, the wire is smaller than the fuse, the wire will fail first causing melting of the insulation and burning. Think of what a fuse is. It's a link that is smaller that the circuit it occupies. Also the longer the wire is changes it's resistance. This will also heat up the wire and not blow a fuse. This is a big problem in homes, where a person adds a larger breaker to the fuse panel. Of corse the breaker won't go off. But the wiring will be heated up and acts as the weak link.
