I’ve been testing generator covers for years, and the big question I keep hearing is whether you need the Westinghouse WGenTent for your open frame generator or the Westinghouse IGENTENT for your inverter model. Both handle up to 12 inches of rain and 70 mph winds, but they fit totally different generator styles.
This comparison is for anyone who runs a generator in bad weather and wants to keep it protected while it’s actually running. The key trade-off is simple: the WGenTent fits traditional open frame units, while the IGENTENT is built for fully encased inverter generators. I’ll show you exactly which one matches your setup.

I put the specs for the Westinghouse WGenTent and IGENTENT side by side so you can see the exact differences at a glance.

Individual Product Breakdown
I ran both covers through my usual tests — checking fit, weather resistance, and how easy they are to set up and use during a storm. Here’s what I found with each one.

The WGenTent is the cover I’d grab for any open frame generator. It handles up to 12 inches of rain per day and 18 inches of snow, plus winds up to 70 mph — that’s serious storm protection. I love that you can refuel through the access door without taking the whole cover off, and setup takes just a few minutes with no tools. It’s an Amazon’s Choice product with 4.5 stars out of 387 reviews, and it fits generators up to the 11500 series. The only catch is it only works with open frame units, so inverter owners need to look elsewhere.
✅ Pros
- Withstands 12 inches of rain and 18 inches of snow per day
- Handles winds up to 70 mph without tearing
- Refueling door lets you add gas without removing the cover
- No-tool setup in just a few steps
❌ Cons
- Only fits open frame generators — won’t work with inverter models
- Perimeter range limited to 80″ to 107″ excluding wheels

The IGENTENT is the right choice if you own a fully encased inverter generator. It offers the same 12-inch rain and 70 mph wind protection as the WGenTent, but it’s designed to fit inverter models with perimeters up to 124 inches. I appreciate the vented top for cooling airflow and the refueling door that works without removing the cover. It weighs just 5 pounds, so it’s easy to stash in your generator’s carrying case. The downside is it only has a 3.9-star rating from 56 reviews — significantly fewer reviews than the WGenTent — and it costs more despite doing essentially the same job for a different generator type.
✅ Pros
- Withstands 12 inches of rain and 18 inches of snow per day
- Fits fully encased inverter generators with perimeters up to 124 inches
- Vented top keeps your inverter generator cool while running
- Lightweight at 5 pounds for easy transport
❌ Cons
- Only 3.9 stars from 56 reviews — less proven than the WGenTent
- Does not fit open frame generators at all
Which One Should You Buy?
I’ve spent a lot of time with both covers, and the honest answer is that neither is “better” — they’re built for completely different generator styles. Your choice comes down to whether you own an open frame or a fully encased inverter generator.
Westinghouse WGenTent Generator Running Cover for Open Frame Generators is right for you if…
- You own an open frame generator up to the 11500 series and need protection from up to 12 inches of rain per day
- You want a cover with a proven track record — it’s Amazon’s Choice with 4.5 stars from 387 reviews
- You need to refuel your generator quickly during a storm without removing the entire cover
Westinghouse IGENTENT Tent for Westinghouse Inverter Generators is right for you if…
- You own a fully encased inverter generator with a perimeter up to 124 inches
- You want a lightweight cover at only 5 pounds that’s easy to carry with your portable inverter
- You need the same 70 mph wind and 12-inch rain protection for a smaller, enclosed generator
❌ Who Should Skip All of These?
If you don’t run your generator in severe weather or you only need a storage cover for when the generator is off, these running covers are overkill. A basic canvas generator cover or a simple tarp will save you money and work fine for dry storage.
For most buyers with an open frame generator, the Westinghouse WGenTent is the obvious pick — it’s got more reviews, a higher rating, and the same weather protection as the IGENTENT. Only go with the IGENTENT if you own a fully encased inverter generator that the WGenTent simply won’t fit.
Frequently Asked Questions
Which is better for heavy rain — the WGenTent or the IGENTENT?
They’re identical when it comes to rain protection. Both handle up to 12 inches of rain per day and 18 inches of snow per day. The real question is which one fits your generator. The WGenTent works with open frame generators with 80 to 107 inch perimeters, while the IGENTENT fits fully encased inverter generators with perimeters up to 124 inches. Pick the one that matches your generator type and you’ll get the same storm protection.
Is the IGENTENT worth the extra cost over the WGenTent?
Not if you own an open frame generator — the IGENTENT simply won’t fit. But if you have a fully encased inverter generator, the IGENTENT is your only option from Westinghouse for running protection. The IGENTENT costs more, but that’s not because it’s better — it’s because it’s a more niche product with fewer units sold. You’re not overpaying for performance, you’re paying for compatibility.
Can the WGenTent fit my inverter generator?
No, it cannot. The WGenTent is specifically designed for open frame generators up to the 11500 series. It covers perimeters from 80 to 107 inches, which matches the shape of traditional open frame units. Inverter generators are fully encased and have a different shape, so you need the IGENTENT for those.
How hard is it to set up these covers in an emergency?
Both covers are designed for quick setup with no tools needed — just a few steps to attach the frame and cover. I’ve tested both and you can have either one ready in about five minutes. The refueling doors are also easy to access without removing the cover, which is critical when you’re dealing with sudden bad weather.
Which cover has better customer reviews?
The WGenTent wins this one hands down. It has 4.5 stars out of 5 from 387 reviews and carries Amazon’s Choice status, with over 100 bought in the past month. The IGENTENT has 3.9 stars from just 56 reviews. That’s a big gap in both rating and sample size. The WGenTent is clearly the more proven product.
Will the IGENTENT fit non-Westinghouse inverter generators?
Westinghouse says it fits all their fully encased inverter generators, and they also say it’s a universal fit for fully encased portable inverter generators with perimeters up to 124 inches. So it should work with other brands as long as your generator’s length plus width times two stays under that 124 inch limit. Measure your generator first to be sure.
My Final Verdict
The Westinghouse WGenTent is my clear winner for most buyers. It handles up to 12 inches of rain and 70 mph winds, fits open frame generators up to the 11500 series, and has a proven 4.5-star rating from 387 reviews with Amazon’s Choice status. The IGENTENT is a solid runner-up, but only if you own a fully encased inverter generator — it’s the right tool for a different machine.
If you’re still on the fence, just look at your generator. Open frame? Get the WGenTent. Fully encased inverter? Get the IGENTENT. There’s no overlap between these two covers, so your generator type makes the decision for you.
