Yes, you can run an inverter generator in the rain if you protect it from getting wet and use waterproof extension cords.

Your inverter generator cover still needs to be strong enough. You should not run your inverter generator in the rain if the weather conditions are so bad that they can blow away the cover.

Additionally, you can not run inverter generators in the rain without any covers. These machines can not get wet.

This would risk your own safety and can damage your inverter generator and any electrical devices that are connected.

Can an inverter generator get wet?

No, an inverter generator should not get wet. Even closed frame inverter generators are not able to withstand rainy weather conditions on their own.

Getting your inverter generator wet leads to risks of harming the people around the machine and damaging the inverter generator and the connected appliances.

Can you still leave an inverter generator in the rain?

Yes, you can often still leave an inverter generator in the rain if you use the right protection and the weather conditions are not too bad.

More specifically, there are a variety of ways to cover your inverter generator in the rain.

In combination with weatherproof power cords, you could still make things work safely.

At least if the weather conditions are not so windy that the inverter generator cover gets blown away during use.

How to cover your inverter generator in the rain

To cover your inverter generator in the rain you should cover it with protection, move it to a suitable location to run, start it with dry hands, and plug in a waterproof extension cord in a safe way.

There are different ways to cover your running inverter generator in the rain. Each has its advantages and disadvantages.

If you decide to go the DIY route, you want to keep in mind that just solid rain protection is not enough. The inverter generator needs enough ventilation too.

1. Inverter generator tent shelter

Inverter generator tent shelters are as the name implies, basically a small tent you attach on top of your generator.

Two positive points are that these inverter generator tents tend to offer good ventilation and are generally easy to install.

On the flip side, this rain cover option is likely not the safest choice for windy weather conditions.

Partly because the rain could still reach the inverter generator when going sideways.

Additionally, if you have an inverter generator tent without any tent pickets, the wind could potentially blow off the cover.

2. Inverter generator cover

You can easily find inverter generator covers that come down to a protective layer you put on top of your machine.

Some positive points of these are that they are often budget-friendly and easy to install.

At the same time, it is worth mentioning that these look a bit more “fragile” in the sense that the covers tend to be connected to the inverter generator with only a few straps.

This could be suboptimal for windy weather conditions.

Additionally, these do not always look the most ventilated compared to something like a canopy tent shelter.

3. Inverter generator enclosures or sheds

If you plan to use your inverter generator for home backup power, it could make sense to build a separate protective enclosure or shed.

When designed well, these tend to deal better with windy conditions.

On the other hand, you do need to make sure these inverter generator enclosures are still ventilated and sturdy enough.

And even if you like the idea of these sheds, the extra effort or cost of installing one may sound less great.

What should you do if your inverter generator gets wet anyway?

There are a few steps you want to take in case you notice your inverter generator got wet for any reason.

  1. Shut off the inverter generator. Potentially with safety precautions like rubber gloves if necessary.
  2. Move the inverter generator to a dry location while again keeping safety the priority. You might need to let the machine cool down for a few minutes before covering it with something.
  3. Dry the inverter generator. Something like a heater or waiting out the rain storm tend to be the main options.
  4. Check for damage. While this is somewhat standard practice when starting your generator, this step is especially relevant after your inverter generator got wet.

As you can expect, you only want to consider these steps after guaranteeing your own safety first.


Do I need to cover my inverter generator in the rain?

Yes, you need to cover your inverter generator in the rain. Letting the machine get wet involves a variety of risks.

Is it OK to run an inverter generator in the rain?

Yes, it is OK to run an inverter generator in the rain if you protect it from getting wet.

However, you should not run an inverter generator in the rain without a cover or in weather conditions that can blow your cover away.
