DIY Portable Generator Enclosure

Power outage is heavy on your life and your pocket because life stops without electricity; no one can do anything in case of a power outage.

On top of that, the unreliable electricity outage can also be annoying, leading to purchasing flashlights, generators, and other equipment that can help during the power crisis.

Power crises can happen due to natural disasters or due to any reason.

If your business solely depends on power, you must figure out a way to keep the power backup available to keep the company running, bringing in portable generators.

DIY Portable Generator Enclosure

The issue isn’t just getting a portable generator housing; the added cost of gasoline, parts, and the biggest one, the generator shed plans, can also be annoying, but that’s the reality you will have to face and handle at any cost.

Before going into the details, let’s discuss the types of DIY portable generator enclosures.

Types DIY Portable Generator Enclosure

There are different types of generator enclosures, and we will discuss the most common types one by one to help you choose the right one that you need.

Soundproof Baffle Box:

As the name suggests, this enclosure is designed to eliminate the noise produced by the generator.

The generator will make noise, but this generator quiet box will reduce that noise, thanks to the materials used in the generator sound box like mass-loaded vinyl, dense fiberboard, and acoustics.

The soundproof generator box is great for keeping the noise low produced by the generator.

This can be extremely helpful if your neighbors are pissed off by the generator noise you use because they can call the cops for this, as you are allowed to disturb your neighbors for any reason.

Another thing is that it is super difficult to build a generator baffle box, as it’s a complex box compared with other simple boxes.

DIY Wooden Shed Generator:

This is a relatively cheaper option to store a generator, but it isn’t as soundproof as a baffle box.

The wooden shed is one of the easiest to build, and depending on the size of the box you make, you may have to spend around $200 to $300 on a wooden DIY shed to keep your generator safe.

Other than that, the smoke that comes from the generator will make the entire box greasy, so be prepared for that.

Plus, there will be a lot of dirt inside the parcel, so frequent cleaning might also be required.

And the biggest flaw with wooden boxes is that the wood can become warped due to exposure to hazardous elements.

Galvanized Steel Enclosure:

The enclosure made with steel is super durable and has hinged doors to ensure proper ventilation to prevent the generator from overheating.

The galvanized steel enclosure will be the most suitable option because it’s cheaper, secure, and durable, so you will get the best ROI for your money if you invest in a steel shed for your generator.

The best part is that it will be easy to clean the box and the generator, but the dirt will also accumulate in the h.

The only thing that is not good with this is that the edges of the steel box can be sharp, and not being careful can get you injured quickly.

Supplies That You Need For Building A DIY Enclosure:

  • 2×4 lumber
  • Plywood sheets
  • T1-11 plywood siding
  • Aluminum sheets
  • 1/2-inch hardwood railing bars
  • Brad’s nails
  • 1-inch machine screws
  • Deck screws
  • Galvanized screws
  • L-Brackets
  • Roofing shingles
  • Wood filler
  • Wood glue
  • Stain/paint
  • Sealant caulk
  • Bungee cords
  • Louvered vents
  • Measuring tape
  • Table saw or circular saw

Why Is There A Need For Generator Enclosure?

Well, with a generator, it’s obvious why you would need an enclosure but still, if you are a beginner and have never had any interaction with a generator, then keep reading as I am going to drill down into the details about why is there a need for an enclosure for a generator.

So, let’s discuss one by one why there is a need for a Generator Enclosure.


An enclosure will enclose the generator entirely, reducing the sound or noise, and making it peaceful around your home because noise can be pretty annoying.

Imagine turning on the generator at night due to power loss, and you are trying to sleep, then you will realize how important it is to shut down the noise.

An enclosure allows you to put the generator away from a working place so that it can stay protected from the rain, and ventilation can keep it cool because a continuously running generator can get extremely hot, and lack of ventilation can lead to damage to internal parts.


Keeping the generator near your workspace will make the workers annoyed by the hazardous gases or the smoke that the generator will release when running.

No one would be able to focus on work in such an environment.

Therefore, an enclosure allows you to store the generator at a distance safely, so the smoke gets blown away by the wind.

Safety From Water:

The biggest and most important advantage of an enclosure is to protect the generator from natural waterfalls due to rain because mostly the power goes when it’s raining.

Then you will be using the generator, which means, when it’s turned off, you can store it inside.

But when you need to turn it on, you need to put the generator outside due to the smoke.

Still, if it’s raining outside, the enclosure will protect the generator from water, and you will be able to get a consistent and uninterrupted power supply produced by the generator.


So that was all about DIY generator enclosures, and you will be able to make your own shed for your generator after reading this article.
