Setting up your house to run off your RV generator?

I will start by saying I am a retired power lineman my house is setup with the proper hookup for a generator a break before make connection so it doesn't back feed the power company.

My MH has a 7 KW generator. Has anyone setup their RV to feed their house legally. My house panel is setup and has been inspected. I just need to figure out the MH end.

To be honest I haven't looked at the MH to see what I need to do yet. With today's world I think I want to get this setup.

    My Onan 4000 was rated at about half a gallon per hour at 1/2 load, and the RV had a 45 gallon tank (only usable to 1/4 tank, so around 30 gallons usable, so I'd get around 60 hours if I ran it 24/7, or about 2.5 days.

    Though in a power failure, I'd really only need to run it around 6 hours a day or less (enough to run the `fridge and furnace once every 4 hours), so I'd get around 10 days of use before I had to refuel.

    The Onan 7000 is rated at 0.7 gph at half load, or 0.4 gph at no load. I don't know what RV he has, but the Tiffin Allegro Open Road comes with the Onan 7000 and has an 80 gallon fuel tank, so he'd get somewhere between 80 - 150 hours of runtime.

    I've only had one extended power failure so far and it only lasted about a day and it was in warm weather, so I only had to power the 'fridge.

  • All you need is a cord to connect the generator output to the house inlet.
  • Considering your gen likely doesn't have 120/240V output a house transfer switch for individual 120V circuits is a good option. 7KW limits what you can power in the house.
  • :) Hi, I have a manual 6 circuit transfer switch in my garage. I have an RV inlet box outside of my garage, by my trailer. And I use my Yamaha 2400 portable generator to power my house. This is enough to power two refrigerators, my garage door opener, wall sockets for my TV and computer, gas fireplace, and all ceiling lights.

    Works great for me; We get too many power outages in my neighborhood.
