How we picked
This guide compares 10 standby generator listings from the catalogue, all with a title that says standby, whole home, whole house or home generator. The listings are compared on the details each title states and on live prices. The ranking rule is the number of stated details (type, fuel, watts group, electric start, RV ready, CO sensor), then dual fuel before gasoline before not stated, then pool order. The two dual fuel listings lead with 3 stated details each, and the other 8 have 2. Runtime, noise, cold starting, and installation are left to the maker's manual and the source pages.
How to choose
Whole house or the essentials
Standby listings are the whole house side of the Texas backup decision. Their titles say standby, whole home, whole house or home generator, and none of them is portable or an inverter. If you only want to back up a few essentials, the separate guide, Best Home Backup Power Station for Texas Homes, covers portable power stations, while this one stays with standby units.
What the title says about starting
None of these standby listings states electric start in the title. If an electric start matters to you, check the maker's page for each model, since the catalogue only records what the listing states.
Starting watts and running watts in a title
The watt figure in each title is the first power figure the seller states, placed here in the over 9,000 watt group. The title often separates a starting figure from a running figure, but the catalogue records only the first figure. Check the maker's page for the running watts before you decide.
Which fuels the title names
Two listings state dual fuel: the Champion 22,000W and the Generac 26kW cellular unit, both naming liquid propane and natural gas. The other 8 listings do not state a fuel in the title, so the fuel source is not stated by the seller. A Texas home on a propane tank may want a dual fuel listing.
Who connects backup power to a house
Connecting a standby generator to a home is for a licensed electrician, the maker and the local permit office. This guide never covers wiring or installation steps.
What this guide leaves out (and why)
The catalogue has no data on runtime, fuel use, noise, cold starting, measured output, warranty or emissions approval. The guide compares only what each listing title states and the live prices.
Questions
Does this guide cover runtime, noise, cold starting or where to run a generator?
No. The catalogue has no data on runtime, noise, cold starting or measured output, and this guide never gives placement advice. Read the maker's manual for each unit, and the CPSC, CDC and EPA carbon monoxide pages in SOURCE PAGES, without treating this guide as a substitute for them.
Do any of these listings state electric start?
No. None of the 10 standby titles states electric start. If that detail matters, check the maker's page for the model, because the catalogue records only what the listing states.
Which listings state dual fuel?
Two listings state dual fuel: the Champion 22,000W (liquid propane and natural gas) and the Generac 26kW cellular unit. The other 8 listings do not state a fuel.
How are these picks ranked?
Picks are ranked by the number of details each title states: type, fuel, watts group, electric start, RV ready and CO sensor. The two dual fuel listings rank first with 3 stated details, and the rest follow in pool order with 2 details each.
