Main trade-off
WEN 8750-Watt Open Frame Inverter Generator
It runs on gasoline only.
Head-to-head
WEN GN875i vs Westinghouse iGen8200TFc: WEN suits gasoline-only plans, Westinghouse adds two more fuel options
The short answer
Choose the gasoline-only open frame or enclosed tri-fuel flexibility.
Before you choose
The reasoning and the trade-offs
A 6,200W running load on gasoline
GN875i has 800W of nominal margin and iGen8200TFc has 400W. A negative number means the continuous rating is exceeded.
What this is based on
Assume a measured total running load of 6200W on gasoline. Margin = fuel-specific running watts minus 6200. Starting transients, altitude, temperature, power factor and per-leg limits are not included.
Main trade-off
Westinghouse iGen8200TFc
A 50A-shaped outlet does not mean the generator delivers 50A continuously at 240V.
WEN 8750-Watt Open Frame Inverter Generator
- Choose it for
- You need the GN875i 7000W gasoline rating and L14-30R
- You want Gasoline only for factory fuel choices
- Main trade-off
- It runs on gasoline only.
Westinghouse iGen8200TFc
- Choose it for
- You need propane or natural gas with remote start
- You want Gasoline, propane and natural gas for factory fuel choices
- Main trade-off
- A 50A-shaped outlet does not mean the generator delivers 50A continuously at 240V.

Winner by situation
Start with what you need it to do
A 6,200W continuous gasoline load
The WEN supplies 7000W continuously on gasoline versus 6600W from the Westinghouse. That is a modest 400W advantage on the one fuel the WEN supports.

Moving the generator and starting it during an outage
Westinghouse adds propane and natural gas, an enclosure and remote start. Those are practical outage-fuel and ownership differences, with lower running output on the gaseous fuels.

Connecting the specified appliances or home inlet
The WEN product page gives half-load runtime on its 4.2-gallon tank. Westinghouse highlights quarter-load runtime, so headline hours are not an equal-load fuel economy comparison.

Switching Westinghouse to natural gas removes 1320W
The iGen8200TFc falls from 6600W gasoline running output to 5280W on natural gas. A 6200W plan therefore needs load shedding after the fuel switch.

What matters in practice
The differences that matter
A 6,200W running load on gasoline
GN875i has 800W of nominal margin and iGen8200TFc has 400W. A negative number means the continuous rating is exceeded.
How we reached this conclusion
Assume a measured total running load of 6200W on gasoline. Margin = fuel-specific running watts minus 6200. Starting transients, altitude, temperature, power factor and per-leg limits are not included.
A 8,000W total starting event
Against this separately specified total starting demand, GN875i has 750W and iGen8200TFc has 200W of published peak margin.
How we reached this conclusion
Assume the combined load during one motor start is 8000W, including the already-running appliances. Subtract 8000 from the gasoline starting rating. This does not establish surge duration or successful motor starting.
Switching Westinghouse to natural gas removes 1320W
The iGen8200TFc falls from 6600W gasoline running output to 5280W on natural gas. A 6200W plan therefore needs load shedding after the fuel switch.
How we reached this conclusion
6600 minus 5280 = 1320W, a 20% reduction. 6200 minus 5280 = 920W above the natural-gas rating. GN875i does not support natural gas.

Will either generator cover the load?
The result checks hard limits only. Preferences stay out of the calculation.
WEN 8750-Watt Open Frame Inverter Generator
Fits these inputs7,000 running watts and 8,750 starting watts on gasoline. This load plan calls for 1,200 running and 2,900 starting watts with reserve.
Westinghouse iGen8200TFc
Fits these inputs6,600 running watts and 8,200 starting watts on gasoline. This load plan calls for 1,200 running and 2,900 starting watts with reserve.
The estimate adds simultaneous running watts, the largest single startup surge and 15% headroom. Confirm every appliance label before relying on it. Never run a fuel-burning generator indoors, in a garage or near doors, windows or vents.

Meaningful differences
What changes the fit
| What changes | WEN 8750-Watt Open Frame Inverter Generator | Westinghouse iGen8200TFc | Why it matters |
|---|---|---|---|
| Running and starting output on gasoline | 7,000W running / 8,750W starting | 6,600W running / 8,200W starting | Continuous load and brief starting demand have separate limits. |
| Factory fuel choices | Gasoline only | Gasoline, propane and natural gas | Match the available fuel and use its own output rating. |
| Starting system | Electric with recoil backup | Remote and electric with recoil backup | Starting convenience is separate from how the generator is carried. |
| Handling layout | Wheeled open frame | 134.5lb wheeled enclosure | Check the route from storage and how it will enter a vehicle. |
| Connection panel | 120/240V L14-30R plus 120V TT-30R and household outlets | 120/240V 14-50R plus 120V TT-30R and duplex 5-20R | The exact receptacle, breaker and cord must match the intended system. |
| Gasoline tank | 4.2 gallons | 3.9 gallons | Tank size alone does not establish runtime at your load. |
| Power regulation | Inverter, Under 1.5% at full load | Inverter, Under 3% | Check load-specific waveform requirements. |
What you give up
Every choice has a cost
If you choose WEN 8750-Watt Open Frame Inverter Generator
- The open frame is louder than an enclosed inverter despite producing clean power.
If you choose Westinghouse iGen8200TFc
- Fuel ratings fall on propane or natural gas. Check running load and motor starting demand separately.
Recommendation switch
The decision flips if...
You need the GN875i 7000W gasoline rating and L14-30R
Choose WEN 8750-Watt Open Frame Inverter Generator. The WEN supplies 7000W continuously on gasoline versus 6600W from the Westinghouse. That is a modest 400W advantage on the one fuel the WEN supports.
You need propane or natural gas with remote start
Choose Westinghouse iGen8200TFc. Westinghouse adds propane and natural gas, an enclosure and remote start. Those are practical outage-fuel and ownership differences, with lower running output on the gaseous fuels.
What matters in practice
How to make the call
Build the load list on the chosen fuel
The WEN supplies 7000W continuously on gasoline versus 6600W from the Westinghouse. That is a modest 400W advantage on the one fuel the WEN supports.
Check the practical ownership difference
Westinghouse adds propane and natural gas, an enclosure and remote start. Those are practical outage-fuel and ownership differences, with lower running output on the gaseous fuels.
Confirm the connection and installation
The WEN product page gives half-load runtime on its 4.2-gallon tank. Westinghouse highlights quarter-load runtime, so headline hours are not an equal-load fuel economy comparison.
What this comparison cannot tell you
- These are specification-based calculations, not measured generator or motor-start tests.
- Altitude, temperature, fuel supply and individual 120V leg limits can reduce usable output.
- CO shutoff does not make a generator safe indoors, in a garage or under an enclosed shelter.
