You might need to run a portable generator in critical climatic situations like heavy rainfall, snowfall and storm.

Portable generators are designed for such worst conditions that back up the power supply.

You can run the generator, but you will need to operate it with full safety precautions.

Especially, you need to prevent the generator from moisture because there is a significant chance of electrocution.

An investigation from NIOSH surveillance shows that out of 100000 workers- 411 workers were electrocuted each year. And it is the fifth leading cause of death, accounting for 7% of all workplace fatalities.

Thus, you need to cover your portable generator.

Besides these, you need to cover a portable generator to prevent irreparable damage.

Operating the generator by concealing it up with temporary or permanent covers make it run for years.

I suggest you use the permanent cover for the portable generator which we will discuss later.

Once you cover the generator, you can let it run in severe weather situations.

Whether is it rainy or snowy, you will receive sufficient electric supply.

Running Portable Generator in Rain Or Snow

For operating a portable generator in wet conditions, you need to cover the generator.

You can buy a cover for a portable generator. Or you can make it on your own.

  • Tips Before Making DIY Cover


Make sure that the cover you made is waterproof. You can see a demo in the video on how it makes the cover waterproof.

The whole enclosure is made of wood. Meanwhile, the upmost part of the enclosure is covered by plastic. This plastic works as a barrier and prevents water leakage.

You can follow any video but make sure that the cover prevents the wet conditions.


A generator produces heat. To release that heat, you need to make a cover with sufficient airflow passage.

With that vent, the exhaust goes out, and the natural air goes in. It maintains the temperature of the generator.

If enough vent isn’t provided for cover, the generator gets heated to its maximum level, which might be the cause of the fire.

It might permanently damage your generator.

The cover of the portable generator must be windproof. It must have the capability to sustain the normal wind flow.

It is difficult to make a DIY cover to resist high wind pressure. But it must resist normal wind flow.

You can make a DIY cover with the same idea.


You need to make a portable cover if you need to transport the generator from time to time.

With that being said, the DIY portable cover must be lightweight and foldable.

For it to be lightweight, you need to use stuff like fabric, vinyl. This stuff makes it lightweight as well as long-lasting.

  • Pricing

With such outstanding features that can cover up to 3000 to the 10000-watt generators, the price is optimal.

I must say you can go for it to run your portable generator with full safety precautions.

Steel Case Enclosure

You can also use a steel case enclosure. However, there are some downsides to it.

  • Expensive

The steel case enclosure is quite costly because the material is made of steel. But it has long durability.

  • Difficult Installation Process

It’s difficult to install, which requires professional work.

  • Not Portable

The major downside of this enclosure is its portability. It’s heavy, and on top of that, you need to lay a pad of cement to patch this enclosure on which aids additional weight to it.

As a result, it won’t be possible to transport your generator to a different location with this enclosure on. But you can use it at your home.

This enclosure will be a permanent cover.
