Power & priorities
Start with output on your fuel, then check AC starting and how large appliances are controlled. A larger headline rating does not settle either question.

What could it power?
Start with what you want to keep running. Compare generators for your home, understand the tradeoffs, and look beyond the headline kW rating.

01 / START WITH YOUR HOME
What could it power in your home?
Choose your equipment. See what can run together, what needs to take turns, and how generators compare. This is a running-load screen, not a final generator size.
YOUR HOME / RUNNING-LOAD SCENARIOS
Together, or taking turns?
All selected equipment running
Sum of every selected running load. No diversity factor or added percentage.
One flexible load at a time
Motor starting is a separate check
No model below is certified to start your AC or pumps. An installer must check starting performance, voltage dip, fuel supply, and load controls.
What you selected
How the catalog compares for your home
All eight records are grouped by running-load fit. These are capacity checks, not reliability rankings or buying recommendations. Unknown fuel uses the lower of the two fuel ratings.
Budget and quote checklist
$8,000–$16,000 is a broad national Generac installed-system reference, not a quote for your loads or a model. Larger systems, new fuel infrastructure, and complex sites can cost more.
- Verify actual loads, motor starts, and any automatic load management.
- Itemize generator, switch, pad, battery, permits, electrical and fuel work, commissioning, and recurring service.
- Check gas-meter capacity, trenching, panel upgrades, and local siting requirements.
Show the math and assumptions
Taking turns = all loads marked Together plus the largest running load marked Flexible. Flexible equipment is not discarded. Only one flexible load runs at a time; this requires a practical manual plan or properly designed automatic controls. This is not a code demand calculation, a predicted typical demand, or a recommended generator rating.
Startup shows the largest selected additional allowance separately, not added to the continuous capacity filter. Overlapping starts, power factor, phase balance, and generator transient response are not modeled.
Manufacturer sizing guidance ↗02 / LOOK BEYOND THE kW LABEL
Same size. Different ownership experience.
Compare exact models and packages. Features are manufacturer claims; they do not prove reliability. Feature sources checked October 27, 2026.
Package & ongoing costs
A switch included in one package can be an extra in another. Compare monitoring subscriptions, battery, load-control accessories, maintenance, and warranty coverage.
Compare model features ↗Service & owner experience
Find authorized support before choosing a brand. Review counts and complaints need context: installation, service, and generator failures are different issues.
Check local support ↗Who will support it near you?
Enter your ZIP on the manufacturer's authorized dealer finder. Ask who performs warranty repairs, whether they service equipment they did not install, and how emergency calls are handled. A listing does not establish availability or response time.

Reviews without a made-up score
We have not collected a verified owner-review dataset for these exact models. Model pages link to the manufacturer so you can check available feedback. We do not blend unrelated models, invent a reliability score, or treat brand prominence as evidence of quality.

No models match these filters. Try a lower output or another manufacturer.
*Limited warranties have exclusions and separate coverage terms. Champion transfer-switch coverage differs from generator coverage. Model prices are not verified. The planner uses a broad national installed-cost reference, not model-specific quotes.

Your shortlist, without the noise.
Select up to three models above. Output, package contents, and fuel use belong in the same conversation.
Choose at least two models to compare.
PLAN FOR THE OUTAGE
What would the
fuel actually cost?
Explore propane costs at two published load points. A bigger generator’s 50% load is a different electrical demand; these estimates are not an equal-load efficiency ranking.
Estimated fuel expense
Fuel only. Excludes installation, maintenance, exercise cycles, and other costs. Actual consumption varies. Models with conflicting fuel data are excluded.
