Frequently Asked Questions

What’s the main difference between the GenTent XL and the GenTent Standard cover?

The biggest difference is size. The XL fits generators with a perimeter between 104 and 140 inches, while the Standard fits perimeters from 40 to 120 inches. The XL also uses the “Extreme” material with enhanced UV treatment and better cold-weather ratings, whereas the Standard uses the regular vinyl canopy. If your generator’s perimeter is under 104 inches, the Standard will work fine and is the more popular choice.

Is the GenTent XL worth the extra money over the Standard?

Only if you actually need the extra size or the Extreme material. If your generator’s perimeter is over 120 inches, you have no choice — the Standard simply won’t fit. If you’re in a milder climate with a generator that falls within the Standard’s range, I’d stick with the Standard. It’s been tested by thousands of users with 398 reviews and a 4.4-star rating, so you’re getting a proven product.

Will the GenTent Standard cover fit my large inverter generator?

It depends on your generator’s perimeter measurement. The Standard cover fits perimeters from 40 to 120 inches. Measure around the outside of your generator’s casing — if that number is over 120 inches, you need the XL. For reference, the XL starts at 104 inches and goes up to 140 inches, so there’s a small overlap where either cover could work, but I’d go with the XL if you’re near the top of the Standard’s range.

Can I run my generator while using either cover?

Yes, absolutely. Both covers are specifically designed for running operation — that’s the whole point. They use NFPA 701 dual-coated vinyl and UL V-0 flame-retardant rated components, so they’re fire-safe during use. The patented design also maintains proper cooling and airflow, so your generator won’t overheat. Just make sure you follow the setup instructions for exhaust clearance.

Which cover is better for extreme cold or intense sun?

The GenTent XL with the Extreme Edition material is the better choice here. It has enhanced UV treatment for increased sun exposure resistance and extended extreme cold weather ratings for harsher climates. The Standard cover is still rated for sub-zero temperatures and won’t crack or stiffen, but the XL’s Extreme material gives you an extra layer of protection if you live somewhere brutal like northern Canada or the desert Southwest.

How do I measure my generator to know which cover to buy?

You need the perimeter measurement of your generator’s casing. Take a measuring tape and measure the width and depth of the generator’s outer shell, then use this formula: (Width + Depth) x 2. For example, if your generator is 30 inches wide and 20 inches deep, the perimeter is (30 + 20) x 2 = 100 inches. If you get between 40 and 120 inches, buy the Standard. Between 104 and 140 inches, buy the XL.
