Have been looking to see if anyone else thought of this problem. Do you have 1 or at least 2 gauge wire between the battery connection and your inverter? And the length of the wire needs to be no more than 4 to 6 feet. If you are over length of 6 feet that can also cause blowing from under gauge wire.
You have to go from the battery with the positive side being fused to the inverter.
Under gauge wire or over length wire can cause of the inverter fuse, if the load is too much.
Just asking...are you trying to run your whole rig off the battery/inverter? If this be the case...only thought was solar power.
