Learn all the tips and tricks on how to buy the best generator enclosure for your portable generator….
Running a generator in the rain without the use of a generator enclosure can be a difficult task. Therefore, most generator manufacturers do not recommend using their products in wet environments. However, the question remains, when you need a generator as your backup power, mostly during inclement weather, how can you go about using it?
A generator enclosure could be the solution. Today we’ll discuss the best generator enclosure for sale, their pros and cons, the different type of generator enclosures, and DIY generator enclosure options.
Reasons to Have a Generator Enclosure
Weather: Generator enclosures protect generators from harsh weather by keeping water, dust, and debris out of the generator compartment.
Wildlife: They protect generators from animals such as rodents by serving as a physical barrier to prevent contact with the critical components of the generator, such as the engine, electrical parts, and the fuel lines.
Noise: Portable generators generally run off of gasoline and can emit loud and unhealthy levels of noise. Generator enclosures typically reduce noise by trapping sound in a box. The sound will bounce around inside the box, and the box’s walls will dampen the sound.
Security: The generator enclosure also protects from theft and vandalism by making them more challenging to access and moving them away from the site.
Types of Generator Enclosures
Generator enclosures can be grouped into three types, which are often categorized according to their primary function:
Weatherproof generator enclosures – This is a portable generator enclosure that protects the generator from the weather. They are typically rated IP55 or IP56. The generator enclosure is completely protected from splashing water and is also sealed against dust.
Sound-absorbing generator enclosures – These are designed specially to keep areas quiet. Sound-absorbing generator enclosures are needed by individuals who are looking to install a portable generator enclosure to protect the noise it produces from being heard by their neighbors.
Walk-in generators enclosures – provide more space and room for management and maintenance of the system than is possible indoors.
There’re no blackouts at convenient times. And they usually occur in bad weather, such as heavy rain or windstorms, which can damage power lines.
Everyone needs portable generator enclosure plans for their generators. It does not matter if the generators have to stand outside. During the power outage, portable generators are suitable for offices and homes.
There’re numerous options for a generator shed. Standard options are metal enclosures, but they often lack some important advantages of weatherproof enclosures. For example, a traditional metal shed may protect against rain and wind, but it doesn’t protect against temperature change. In addition, they provide airflow and ventilation, but not enough to give complete protection to some diesel generators. Weatherproof generator enclosures can give this due to their sealed construction.
Although a steel-reinforced concrete pad or aluminum may work in some situations, they should always be weatherproof to ensure the complete protection of the generator. A good design should reduce all risks to the generator set.
When it comes down to it, giving the enclosure that protects the engines are a worthwhile investment. Therefore, engine protection is the main objective of the portable generator housing.
To ensure good protection from the elements, you must choose a stable and durable generator enclosure.

How to Build a Generator Shed Enclosure
Noise protection generator enclosures are almost always necessary. In addition, you would require a quiet generator in areas where the use of generators outdoors is limited unless the sound insulation is built into the housing. This generator enclosure is slightly larger and may cost a little more than a simple weatherproof system, but they allow for overall noise reduction.
This type of generator shed, such as a soundproof baffle box, leads to a considerable reduction in noise, even if not all of them reduce the noise ultimately. Achieving this requires the generator shed to be higher and more extended in overall size to allow for additional insulation within the housing walls. In addition, they often have a silencer on the inside of the shed. Finally, many constructions also extend beyond the cooler and have silencers to help further reduce the system’s noise.

The best practice for each unit is to follow the manufacturer’s recommendations. A portable generator enclosure that offers complete protection for the unit, including noise and weather protection, while being fireproof, requires the creation of a custom option. A walk-in generator shed may be best suited for these applications.
Walk-in housing is often designed to offer all of these benefits – they are weatherproof, soundproof, fireproof, and completely insulated to be quiet. Because they are customized, they can be constructed to meet the specifications of all make and models of generators, including all backup generator models and routinely used systems. At least the housing of the generator set should be built for the specific class and type of system.
What to Know
The properties of the generator determine the generator shed plan for your engine. Generators are an essential part of human life, especially if there is a persistent power failure or simply during an outdoor activity.
If the generator is left outside, it’s exposed to many types of hazards, such as adverse weather conditions, so building or choosing generator shed plans should not be a problem for your portable generator. The first thing to consider when looking for a portable generator enclosure should be the dimension of your generator.
There are several factors to consider when choosing a portable generator enclosure; aside from airflow, protection, and noise, there’re others that depend on personal preferences.
These can include the price, generator usage, type of outdoor activity, ease of installation, portability, and other features. Generator enclosure accessories like the transfer switch and fans, electrical systems can also add significantly to the cost, so keep that in mind when comparing prices.
In addition, the formation of the portable generator enclosure must be able to upgrade the arrangement of the airflow. Therefore, the interior of the housing should be able to both a motor and an alternator.
The airflow of the generator shed should draw in ambient air through the entire inlet flow path of the eaves section of the roof structure and then move inward to cool the motor. In contrast, the generator pushes air from inside the enclosure through the outlet flow path in the attic section and out of the generator shelter.
The airflow from the generator shed should suck the environment through the entire air intake path of the eaves part of the roof structure. Then it moves inward to cool the engine. At the same time, the generator draws air from inside the housing through the outlet flow path in the attic part and out of the generator guard presses. proper ventilation on the generator’s air intake can be improved by installing fresh air louvers on the shed’s walls.
The portable generator housing should effectively protect the engine from the effects of adverse weather conditions such as rain, floods, and subdued environments.
In most cases, portable generators are God-sent materials in devastating weather. Therefore rain can seep into the engine, causing corrosion or, in worse situations, electric shock. Thus, the portable generator enclosure design should include weather, maintenance, storage, and engine operation functions.
The generator shed should have a large ventilation opening to allow heat to dissipate, ventilation openings with automatic blinds to keep out rain, rodents, birds, and insects, and a high-performance fan to cool the engine in warm weather. The fan cover should be wired per OSHA requirements, which will help reduce the likelihood of personal injury.
Above all, the housing of the portable generator should be provided with arrangements to lock all the sheds, which will help prevent the portable generator from being stolen. In addition, the generator shed should allow electrical connections to be kept dry to reduce the risk of electric shock in bad weather.
Therefore, the shelter of the portable generator should be based on other external parameters, such as affordability, durability, longevity, and above all, effective and efficient performance based on high-quality airflow, protection from rainwater, and contribution to sound insulation.
Potential Disadvantages for All Generator Housings
The disadvantages of buying generator housing are obvious.
- They are bigger than the generator and take up a lot of space.
- The type of structure dictates proper installation, often with the assistance of a professional.
- Most importantly, they are not portable.
When you purchased your portable generator, you wanted to use it at home and out at the campground or work. You can move the generator, but the steel construction stays in place, so if it rains around this campfire, you need another solution to run your generator in the rain.
By buying or building a roof or generator enclosure, you can operate your generator when you need it in heavy rain or wind. Not only that but keeping your generator outside in a safe enclosure can help protect you from potential carbon monoxide buildup.
The proper use of any shelter will ensure that your power connections are clean and dry and that they remain clean and dry during operation so that you can safely restore power during the storms that approach you.
I’ve always been a lover of Mechanics and the engineering that goes on behind it. Naturally had a knack for fixing things and i’ve had lots of adventures that generators are second nature to me.
