Does this mean you have the DC wiring from the batteries to the converter using 12 AWG? If so, your fuse won't protect the wire in case of catastrophe and the inverter is going to see a huge voltage drop. For a Xanterx SW 1000, the recommended DC wiring is #2 AWG.
I have a 200A inline fuse on the DC side which is hooked up to the batteries with #2 AWG welding cables.
The AC side running from the In deter to the panel is #12 AWG
