Naz, not pitching, but check out Generac. Our's is 10+ yrs old, old/lower tech, (the new ones are titz), and runs better than my Rolex. Only 12 kW, but runs 85% of our house, comes on ~20 seconds after a power out, and turns off seamlessly when power comes back on.

And, no one needs the top kW to run a 'whole house' since when was the last time anyone had 'everything on' in their house?!

They also make diesels, (a neighbor has one), that will run 24/7 for as long as one has diesel fuel to pour in, but it's overkill in 'burbs, imo.

If you have piped Nat Gas, it is a no brainer, imo, and even if you don't. a small tank of propane buried in the yard will run the sumbitch for as long as you might need. But be sure the install is careful, and the electrician knows what he/she is doing. Not for a 'first time install' by any electrician, imo.
