Westinghouse 11000 Peak Watt Dual Fuel Portable Inverter Generator, Remote Electric Start, Transfer Switch Ready, Gas and Propane Powered, Low THD - Safe for Electronics, Parallel Capable, CO Sensor

Why I chose a high‑output inverter

I’ve used plenty of open‑frame generators around jobsites and during outages, but I’ve wanted an inverter that could handle whole‑home essentials without beating up sensitive electronics. The iGen11000DFc promised inverter‑grade power at a scale normally reserved for conventional units, plus dual fuel and a transfer‑switch‑friendly outlet set. After living with it through setup, testing, and a few simulated outage runs, here’s how it stacked up.

Setup and first start

Unboxing is straightforward, but be realistic about the weight: this is a two‑person lift. The wheel kit and rubber feet go on with basic hand tools. The oil fill is tucked low; Westinghouse includes a shaped funnel that makes hitting the fill spout much easier. I appreciated the plug‑and‑play approach—oil, funnel, 12V battery charger, remote fob, and a decent little tool kit are all in the box.

The battery arrived charged. After adding oil, I tried propane first. The LP connection on this model uses a hose‑mounted regulator rather than a regulator fixed to the generator, and the connection point is in a slightly awkward spot on the housing. It works, but plan on a minute of routing to avoid chafing. One pro tip: before the first run, hit all hose connections with a soapy‑water spray and watch for bubbles. On my unit, the hose‑to‑regulator fitting needed an extra snug.

Remote start with the key fob worked on the first try. The push‑button start on the control panel is quick too, and the recoil backup is reasonable to pull for an engine this size. The rotating digital display is clear, showing fuel level, output, remaining runtime, voltage, and total hours—handy for maintenance intervals.

Power quality and capacity

This is the reason to buy an inverter. The iGen11000DFc delivered clean, steady power in all my tests. On gasoline, it’s rated 11,000 peak/9,000 running watts; on propane, 10,000 peak/8,100 running. I fed a mix of 120V and 240V loads—refrigeration, a well pump, gas furnace blower, lights, a few receptacle circuits, and a 240V pool pump. Voltage and frequency stayed locked at 120/240V and 60 Hz, and the sine wave looked textbook on the scope. That matches the sub‑3% THD spec and is the main reason I’m comfortable plugging in networking gear and home office electronics without a separate UPS.

Compared to a traditional AVR‑regulated open‑frame unit I own, motors ran cooler and drew slightly less current on the iGen. That’s exactly what clean power should do: less wasted heat, less hum, and less stress on appliances.

The 50A 14‑50R and 30A L14‑30R outlets being transfer‑switch ready is a big deal at this wattage. If you’re planning a home connection, work with an electrician to match the generator outlet to your switch or interlock, and confirm neutral‑ground bonding requirements for your setup.

Dual‑fuel behavior

Gasoline gives you the headline wattage and the longest runtime. Propane trades a bit of output for fuel stability and convenience. I ran a full afternoon on a 100‑pound propane cylinder with no hiccups. If your outage plan leans on LP, note the slight output reduction at 240V and plan your load priorities accordingly. For gasoline, I keep treated fuel on hand and rotate it; the onboard fuel gauge and remaining runtime readout help avoid guesswork.

The eco mode correctly idles the engine down with no load, and it ramps up promptly when demand hits. Above a couple of kilowatts, the engine will be at a steady working speed whether eco is on or off, so don’t expect dramatic noise changes under moderate to heavy loads.

Noise, heat, and runtime

This is quieter than comparable open‑frame 9–11kW generators, especially at low load. But it’s still a big 457cc engine—think “neighborhood‑friendly during a storm,” not campsite‑quiet. The sealed housing does a good job of managing sound and heat. After extended runs, surface temperatures were manageable around the panels, with expected hot zones near the exhaust.

With a 9.8‑gallon tank, Westinghouse cites up to 17 hours at 25% load. My gasoline runtime at a light to moderate household load lined up with that ballpark. The fuel gauge and “remaining time” readout were useful and reasonably accurate as load stabilized.

Controls and outlets

The front panel is laid out logically. You get:
- Two GFCI 120V 20A household outlets (5‑20R), covered
- One 120V 30A L14‑30R (transfer‑switch ready)
- One 120/240V 50A 14‑50R (transfer‑switch ready)
- 12V charging port and the included charging cable
- Eco mode switch and master breaker

Outlet covers are a nice touch for weather protection when not in use. The data center rotates through status points automatically, and pressing the button cycles quickly if you don’t want to wait.

Portability and storage

The enclosed frame gives you a smaller footprint for the power than most open‑frame units, and the collapsible handle helps. That said, the wheels are on the small side for curbs and thresholds—plan your path. If you move generators over rough surfaces frequently, you’ll notice the difference versus larger wheels on open‑frame models.

Because the tank sits under a molded top, you can’t just throw a board across the frame for a makeshift rain roof like you might with an open‑frame. Use a purpose‑made generator tent or canopy that preserves clear exhaust flow, and never enclose the unit. The built‑in CO sensor is there for a reason; give it plenty of fresh air.

Maintenance and reliability notes

The 457cc OHV engine has a cast‑iron sleeve and automatic low‑oil shutdown. Oil access is fine once you know where it is; the included funnel is essential. After the initial oil change, I set reminders based on the hour meter.

A couple of small nitpicks from the first look inside: cable management is tidy, but a few zip‑tie tails were left long and sharp from the factory. Snip them flush during your first oil service to save your knuckles.

The 12V battery charger port is great for keeping the starting battery topped off between seasons. I test‑start monthly on propane and quarterly on gasoline and let it run under load for 10–15 minutes.

What it’s best at

• Whole‑home essentials through a transfer switch, with headroom for a 240V pump or similar load
• Backup power where clean output for electronics is non‑negotiable
• Users who want dual‑fuel flexibility without stepping up to a permanent standby system

Where it comes up short

• It’s heavy. The wheel kit helps, but plan on two people for loading/unloading.
• The LP hose/regulator setup works, but the hose‑mounted regulator is bulkier and easier to bump than an onboard regulator. Double‑check those connections.
• Noise is improved over open‑frame peers but still substantial at higher loads.
• The smaller wheels and enclosed top make it less convenient to move over obstacles and harder to “improvise” weather protection than an open‑frame design.
• Price. You’re paying for inverter power at high wattage; if you only need raw watts, a conventional generator will be cheaper.

Safety and compliance

It’s EPA compliant, includes a CO sensor, and ships function‑tested. Treat the CO sensor as a last line of defense, not a license to run in marginal locations. Keep it outdoors, 20+ feet from openings, exhaust pointed away from the house, and use long‑duration outdoor‑rated cords or a proper transfer setup.

The bottom line

The iGen11000DFc hits a sweet spot that didn’t really exist a few years ago: inverter‑grade output with real 240V capacity for household circuits and larger motors. In my testing it started reliably, produced clean, stable power, and offered the flexibility of gasoline or propane without drama. The control layout, digital display, and included accessories reduce friction during both setup and actual outages.

It’s not perfect. The LP connection design is a little clumsy, it’s not a featherweight, and while quieter than open‑frame brutes, it’s still a big generator. But those are manageable trade‑offs for the power quality and features on offer.

Recommendation: I recommend the iGen11000DFc to anyone who needs clean, high‑capacity backup power for a home or small business and wants dual‑fuel flexibility without committing to a fixed standby installation. If your priority is the lowest possible cost per watt and you don’t care about THD or electronics, a conventional open‑frame unit will save money. If you value safe power for sensitive loads, transfer‑switch‑ready outlets, and a well‑thought‑out user experience, this inverter earns its keep.
