Reporting back on the topic. I ordered my generator and received it this past Friday. Today, the electrician came over and installed the 50 amp inlet to my breaker box along with the interlock. We tested it out before he left and everything worked great! AC came right on (woo hoo!) and fridges and lights in the house were on. It is a duel fuel generator, propane and gas. For the install, I just bought a 20lb propane tank to test it out. The electrician told me to break in the generator over the next several weeks. He said I probably want to get it up to about 6 hours. He said I could break it out into hour, 2 hour increments so I don't get the neighbors too mad at me.
Now exploring the different fuel options. I like propane, and was able to power up what we wanted in the house with it. Advantage of the propane is that I don't have to deal with storing fuel, putting it in the car if it does not get used in X amount of time, then emptying the fuel out of the generator if it doesn't get used up. But of course the run time and power is not as great as gas. Looking at 5, maybe 6 hours on the 20lb tank. So I would probably need to get a 50lb tank and a couple of other 20lb tanks if I know a weather event is coming. For gas, I have been looking at just putting E0 in it so there is not as much maintenance needed. But there closest E0 pump is about 30 minutes away. So probably would need to fill up several tanks of that. Metal gas cans are not cheap.
All in all I would say I am pretty happy with the purchase and process. For a little over $2k in (generator was $1,250, 25ft 50amp cord was $140, and inlet installation was $770), I now am able to power up the house whenever needed. Since moving to the Houston area, we have had two major power outage instances. One was a few years ago where pretty much everything froze over and we had no heat for several days. Hanging out in a below 50 degree house is no fun. Then this past hurricane where we had no power for several days where it was cooler to hang outside in 90 degree heat than it was to be inside.
If there is anyone in the Houston area that needs a good electrician referral, let me know. The company I used was awesome.
