Stan that 13kw will run your whole house no problem..just keep most of the lights off,only run what you need and you'll do fine..I sell 10kw water cooled diesel units to people all the time to run their homes during emergencies,they will actually do more than the 10kw rating. I'm sure in South Central FL that A/C is very important..set it up right and it'l last you..glad to read you went with the breaker interlock, nothing really to go wrong there,no circuit boards to crap out when you need it the most and cant get parts in the middle of a hurricane..good deal
