I can't help you with a specific location, but I can give you some criteria.
An 1,100 watt inverter will draw as much as 100 amps DC. That is much more than your DC fuse panel can handle, so you need to wire it directly to the batteries with a 100A fuse or breaker near the battery. You also need to minimize the distance to the batteries. A location 10' away will require #4 wire to keep the voltage drop down to about 1/2 volt.
