I like a gas portable 30A unit. Something like this:
https://www.samsclub.com/ip/10-000-...rt-GP8000E/13572122433?classType=VARIANTThats rated at 30A... all your plugs and wire and breaker needs rated at 30A.
Get you an interlok kit.
https://interlockkit.com/Put the interlock kit on your panel, its specific to your panel, it keeps your main off and gen breaker on or main on and gen breaker off... cant' be both and this keeps you from doing that.
Add a 220V 30A breaker to your panel. Put a 30A gen outlet somewhere. Run 30A wire white black bare and red between breaker and outlet. Your cord will have two male ends or some such configuration. I have a short male to male to covert things.
Anyway thats that.
I realized my power feed out to the barn could also be my gen feed to the house. So my gen resides in my barn and I hook it up and get it going indoors (separate building) and when its raining snowing and dark easy easy.
I added emergency lighting to light my panel and gen area while power was out so its not dark when I am hooking it up.
Good luck.
People will complain about this but this is the cheap and effective way of doing it that the people on this site are interested in.
Doing it this way that gen can die and you can go buy another and plug it in. Easy Easy.
They make dual propane and gas gens. You could go that route. If it was me I'd have multiple gens with multiple ways to run them. i.e. gas, propane, pto, deisel.
