Overview
The iGen11000TFc delivers inverter-quality power at home-backup scale on three fuels, with per-fuel running and starting watts published and stored separately: 9,000 W running / 11,000 W peak on gasoline, 8,100/10,000 W on propane, and 7,200/8,800 W on natural gas. Its 457 cc engine feeds a 120/240 V panel — an L14-30R locking outlet, a 14-50R, and two GFCI-protected 120 V duplex outlets — with THD officially ≤3%, so it is inverter-clean despite the size. A CO Sensor automatically shuts the engine down on carbon-monoxide buildup. Electric, recoil, and remote start; parallel capable. There is no TT-30R and Westinghouse lists RV Ready as No, so it is recorded as not RV-outlet equipped despite the 240 V receptacles. Runtime is 19 h at 25% load on gasoline (9.8 h on propane); no 50%-load figure is published. At 86.6 kg dry it is a wheeled cart unit, not a carry generator.
Variant note: Carbureted tri-fuel iGen11000TFc with CO Sensor. Not conflated with the non-CO iGen or WGen conventional families.
Data note: THD '≤3%' normalized to 3 with the qualifier preserved. Noise '64 dBA' stored under unknown_basis (no load basis anywhere official) — noiseClass unknown. No TT-30R; page 'RV Ready: No' — rvOutletPresent=false despite 120/240 V receptacles. CONFLICTS preserved: the manual's boilerplate on p.13 wrongly references a '120V 30 amp RV receptacle' and a '1.11 gallon' tank — both contradicted by the same manual's own spec page (7.92 gal tank, no TT-30R) and treated as copy-paste errors, not the record's values. Grounding text conflicts between the product page ('Bonded Neutral') and the manual ('Bonded to frame') — both noted, neither is a published spec field here. CARB: not compliant per page; EPA certification not stated (null, not a denial).
Specifications
Running and starting watts are never collapsed; every runtime figure carries its fuel and load basis; THD is shown only when officially stated numerically. Core values' original claims and sources are in the provenance table. The final group is computed from the fields above and marked as derived.

Use cases
- High-output home backup via a transfer switch: 120/240 V with L14-30R and 14-50R outlets
- Storm resilience with three fuel paths including natural gas from a house line
- Sensitive-electronics loads at scale (≤3% THD officially stated)
- Long outages: 19 h at 25% load on gasoline, indefinite on natural gas supply
Cross-category fit flags (stored for future battery-vs-generator pages, not yet used for ranking): RV not suitable · camping not suitable · home backup suitable · apartment use: no · sensitive electronics: high · noise class: unknown.
Strengths and weaknesses
Strengths
- Inverter-clean ≤3% THD at 9,000 W running — rare at this output
- Tri-fuel with per-fuel running and starting watts officially published
- CO Sensor auto-shutdown documented in the manual
- GFCI 120 V outlets and covered receptacles; electric + remote start
- 120/240 V with both L14-30R and 14-50R for whole-panel backup
Weaknesses
- No TT-30R and Westinghouse lists RV Ready: No — not recorded as RV-outlet equipped
- Noise figure (64 dBA) has no load basis — excluded from noise ranking here
- No 50%-load runtime published; propane cylinder size unstated
- Not CARB compliant; EPA certification not stated (null)
- 86.6 kg — a wheeled cart, two-person maneuvering
Comparisons featuring this generator
High-Output Dual & Tri-Fuel Home-Backup Generators: DuroMax XP13000EH vs Westinghouse iGen11000TFc vs WGen9500DF vs Champion 201412 vs DuroMax XP9000iH vs Firman WT05571
Six high-output 120/240 V multi-fuel generators for whole-house backup through a transfer switch — 5,500–10,500 W running, dual- and tri-fuel, conventional and inverter. They separate on output, fuel flexibility, power quality (only the inverters offer clean THD), and one critical safety point: five have CO-shutdown, one documents that it does not.
