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.

Verdict
For raw output the DuroMax XP13000EH leads at 10,500 W running / 13,000 W peak dual-fuel, with L14-30R and 14-50R outlets and CO Alert shutdown. But if you run sensitive electronics during an outage, the Westinghouse iGen11000TFc is the standout: a tri-fuel INVERTER delivering ≤3% THD at 9,000 W running — inverter-clean power at a wattage where almost everything else is a conventional AVR unit. The Champion 201412 is the fuel-flexibility pick, with per-fuel watts published for gasoline, propane, AND natural gas, so a house gas line means indefinite runtime. The DuroMax XP9000iH is the transfer-switch-native inverter (it ships with an ATS plug) at 7,600 W and clean-ish output, though it publishes no THD number. The Firman WT05571 is the most versatile panel — tri-fuel inverter with a TT-30R plus 240 V outlets and CSA certification — and by far the lightest at 59.6 kg, trading peak wattage for portability. The Westinghouse WGen9500DF offers the most conventional output value (9,500 W running dual-fuel) but is the one unit here that Westinghouse documents as having NO CO sensor — a real consideration for an outdoor-only machine.
Best for each scenario
| Scenario | Pick | Why |
|---|---|---|
| Maximum output | DuroMax XP13000EH | 10,500 W running / 13,000 W peak dual-fuel, 120/240 V with L14-30R and 14-50R, CO Alert shutdown. |
| Cleanest power at high output | Westinghouse iGen11000TFc | Tri-fuel inverter with ≤3% THD at 9,000 W running — inverter-quality power at whole-house scale. |
| Most fuel flexibility | Champion 201412 Tri Fuel | Tri-fuel with per-fuel running and starting watts published for gasoline, propane, and natural gas — indefinite runtime on a house line. |
| Inverter backup wired to a transfer switch | DuroMax XP9000iH | Ships with an ATS plug for automatic transfer switches; 7,600 W running, 120/240 V, and a 20 h quarter-load runtime. |
| Lightest high-output multi-fuel | Firman WT05571 Tri Fuel Inverter | Tri-fuel inverter, TT-30R plus L14-30R and 14-50R, CSA and PGMA certified, at just 59.6 kg. |

- 14-50R delivers only 22.9 A / 5,300 W from a single unit despite the 50 A receptacle form
- 59.6 kg — wheeled, not carried
Sources and evidence
- SAFETY NOTE: the Westinghouse WGen9500DF is the one unit here that its manufacturer documents as having no CO sensor ('Carbon Monoxide (CO) Sensor: No'). It is published because that absence is explicit, not ambiguous — but all fuel generators are outdoor-only, and this one has no automatic CO shutdown as a last line of defense.
- Per-fuel running and starting watts are stored separately in each record; the matrix shows the gasoline headline. Natural-gas runtime is supply-line dependent and unpublished for the tri-fuel units.
- Only the inverter units can offer clean THD; of them, only the iGen11000TFc publishes a number (≤3%). DuroMax markets 'Low THD' on the XP9000iH without a figure, so it is null and its sensitive-electronics suitability is capped at medium.
- None of these is recorded as RV-outlet equipped except the Firman WT05571 (TT-30R); DuroMax's 'RV Ready' marketing on the XP-series lacks a TT-30R and is not treated as receptacle evidence.
- All values come from each generator record's official-source provenance, checked 2026-07-08; recorded conflicts (e.g. DuroMax runtime and weight discrepancies) are on each linked generator page.
