To answer the original question, yes you definitely need a fuse in the battery connection. NEVER connect a wire to the battery without a fuse in the positive lead. If there is ever a short in the wire a fire will likely result.
A 400 watt inverter will pull nearly 40 amps at full load. This will require #8 wire at minimum. Larger would be even better. A 50 amp fuse should be enough. If you run larger wire you can increase the fuse size appropriately.
