I've done a little research, but haven't pulled the trigger. A few things I've learned.Somebody on the CT mentioned whole home generators. Does anybody have any experience with this? Our house already has a natural gas line.
Natural gas de-rates the power output by about 20% from nameplate rating.
Are there restrictions, legal or practical, on where you can locate it?
Will you need an enclosure for noise, vandalism, theft, zoning, HOA etc?
If you are in hurricane prone areas, a hurricane rated base slab might be a good idea. Proper mounting to it also makes it less likely that your generator "sprouts legs" and walks away.
Calculate your actual electric load properly. Do you need everything on under generator power conditions that you use under normal conditions? The bigger the generator, the more costly. Some stuff is obvious. Refrigerator, freezer, HVAC, well pump, sump pump... Include at least one TV plus your outside signal source. Emergency info will come through TV.
Do you need washer/dryer powered, or can laundry pile up for a while? What do you need for cooking?
Manual or automatic cutover switch?
Make sure the electrician who installs the cutover switch is experienced in doing this.
Autostart or manual? Do you want to be doing manual start at 3 AM during a thunderstorm or heavy snowstorm?
Do you need/want instant on, or is some delay (3 minutes, 5, 30 etc.) OK?
Automatic test or are you willing to turn it on to test manually at the recommended test interval?
If you get it, hope you never have to use it for real.
