Best Generator Enclosure Buying Guide:

If you need the best generator enclosure for your generator, you have to buy the right unit. It’s necessary to match a product with your needs, preference, and functionality before you can add it to your cart. Here are some considerations you have to go through when making your selection.

Generator enclosure type

Generator enclosures come in various types depending on the design, functionality, and installation. Here are the few generator enclosure options to consider.

Rigid Generator Enclosure

If you’re looking for a generator enclosure to use at home and you’re planning to use it frequently, you can decide to go with one of the rigid generator enclosures. An inflexible generator enclosure comes as a structure designed to be mounted outdoors to provide the much-needed shelter or storage space. The best part is, these models are multipurpose. Most of the rigid enclosures are used as fixed storage spaces in the backyard. Their sizing varies from large and room to compact and to confine. Very few of the rigid generator enclosures are portable.

Flexible generator shelters

If you need a generator enclosure to use while you camp, tailgate, or while on the road with your RV, a flexible generator enclosure is your perfect choice. They come as small shelters or tents with a canopy. They are available in various sizes and styles; they are completely portable and lightweight, in most cases. Most of them look like a small tent that fits over the top of the generator.

Most of these flexible generator enclosures use a framing system that keeps them spread well on the generator. Some come with ventilated tops to allow airflow, while others feature open-able sides. The fabric used here is waterproof or water-resistant to keep your generator dry and safe during inclement weather.


Of course, it comes without saying that you need to invest in a durable generator enclosure. But that isn’t easy if you don’t consider how the generator is built. You need to consider the materials used and the structure overall. Since you’re buying a generator enclosure to keep your generator safe while it’s running during inclement weather, you must understand its construction needs to be heavy-duty and weather resistant. It needs to be highly weather resistant to protect your generator from moisture, rain, snow, and UV rays.

Assembly and Installation Ease

A generator enclosure will mostly arrive in pieces that you will need to put together. Most of these units feature an easy assembly and installation but not all the time. That is why you need to check the installation and assembly easiness before you purchase. Check the product reviews to understand how it faired for other uses.


I don’t know if you noticed there is compatibility mentioned in the above reviews. The generator enclosures come with particular sizes meaning they only fit specific models. What’s more, other models are built to suit particular generator capacity depending on the generator size, fumes produced, and the cooling needed. You must understand if the generator enclosure you’re about to buy is compatible with your generator.

Best Generator Enclosures (FAQs)

Q: Why should I buy a generator enclosure?

A: There are a couple of reasons why you should buy a generator enclosure. The list is long, but I will list for you some of the primary reasons. Here we go:

Q: Protects your generator from weather elements

A: As I mentioned earlier, a generator enclosure is mostly used to shelter a generator while it runs during inclement weather. And as you well know, power loss comes when we least expect and mostly during extreme weather.

Heavy rains, snowstorms, wind, and other weather conditions can affect your generator performance or even cause damage. And since it’s never safe to use a generator indoors, you need to have a better way to protect it from the bad weather. That’s one reason for buying a generator enclosure.

Helps with noise reduction

If you’re using your generator in an urban residential area, a generator enclosure can be a sure way to keep your neighbors happy. In those remote or rural areas, noise might not be an issue, but for the kids and your peace of mind, a generator enclosure can be a handy structure. If you get the best noise-reducing enclosure, it will get easier to keep your outdoors silent, especially when camping.

Mobility and Portability

Suppose you have a large generator with no wheels and you need it moved. In that case, you can get a cart-like generator enclosure to help protect the generator and also improve its mobility and portability. Some generator enclosures feature wheels that provide the needed mobility convenience, especially for the campers.

Protection from dirt, debris, and intruders

A generator enclosure, especially a tent or cover, offers ideal storage equipment to protect your generator from dust, dirt, and debris. It’s also a better way to protect your investment from intruders that can cause damage to your equipment.

Can I build a DIY generator enclosure?

Of course, you can! However, there is much that you need to consider. While building your generator enclosure, you have to make sure the materials you use are heavy-duty and weather resistant. What’s more, the unit has to be well ventilated while also keeping all the moisture out. It needs to be sturdy enough if you live in an area that received heavy snowstorms. Instead of all these hassles, it’d be best to invest in an already built unit.


The best generator enclosure will offer you a lot from the peace of mind to protecting your investment. This post is here to help you move forward with an easy mind while searching for the best generator enclosure. Use the buying guide I have included here to smoothen the process. Good Luck!
