Can a Portable Generator Be Used in the Rain?

Can a portable generator be used in the rain? Can my portable generator get wet? These are both common questions year-round campers ask. If you love camping out in the winter months or early spring, then this answer is crucial, especially if you camp in parts of the country that experience more rain than average, or you’re braving freezing temperatures.

Can a portable generator be used in the rain? No. When not in use, the generator should be covered with a generator-specific cover. For permanent setups, you can use a steel or plastic enclosure to protect the generator from the elements. Even the slightest amount of moisture can do serious damage to the outlets on a generator, which is why you should always keep it covered. Aside from doing some serious damage to your generator, a generator that gets wet during operation can electrocute you.

Read on to learn how to stay safe and what you can do to protect your generator, and yourself in the event you find yourself stuck outdoors in the middle of a downpour or another type of inclement weather situation.

Camping Out During the Rainy Season

Manufacturers stress how unsafe it is to use an inverter generator indoors or too close to an open door or window, but they usually don’t mention whether or not these generators can handle getting wet.

Unfortunately, they can’t. If an inverter generator is left out in the rain, the water can easily make its way into the generator’s outlets. If the generator’s electrical panel gets wet, you risk electrocution and significant damage to the generator.

Some models come equipped with ground fault circuit interrupt outlets, which automatically switch off when they become wet. But even if the outlets shut down, the generator is still considered dangerous.

If used incorrectly, an inverter generator can electrocute you or cause a serious shock, considering the amount of electricity they can produce. Using one in wet conditions, or when your hands are wet, will inevitably lead to electrocution.

Camping Out During the Rainy Season

If you store your generator outdoors, in a place that’s not well-protected from the weather, make sure you check the GFCI receptacle, in addition to the other control panel electrical components, before you fire it up. Ice, snow, and moisture of any kind can damage the generator and cause a short.

The Generac 7117 GP2200i Portable Inverter Generator is one of the top camp generators on the market, but despite its innovative design, it still requires a shelter, enclosure, or tent of some sort, to protect it from the elements. This goes for any generator on the market, even those that are specifically designed for camping.

How to Protect Your Generator

The inverter generator is able to produce powerful voltage, but when you add rain to the mix, this can permanently damage the generator, or seriously harm someone. Even a small amount of moisture, such as morning dew, can lead to disaster.

Because of this, it’s important to protect the generator from exposure to rain, snow, and moisture.

Fortunately, there are options you can choose from, each of which can provide the type of protection you need to run your generator safely.

Options include:

  • Canopies
  • Sheds
  • Special generator covers

Generator canopies can easily protect a generator from the elements, allowing you to operate it safely. Obviously, these canopies are waterproof and double sealed and can provide ultimate protection in the event of a downpour. However, they may not offer enough protection if you’re dealing with high winds in addition to rain or snow.

In the right conditions, the canopy can be a great, effective option, and one that won’t interfere with the generator’s portability or installation. Keep in mind, you can’t use any type of cover or canopy to protect the generator because it can easily cause the generator to run too hot and overheat.

Covers and canopies are specially designed to protect a generator from the elements while also promoting airflow, allowing the generator to run smoothly, without overheating.

Generator Covers

A top of the line generator cover can be used in rain and snow, and like the canopy, is designed to keep the generator nice, cool, and dry. Some brands of covers, such as Gentent, even claim that their covers can be used even in intense temperatures or during a hurricane. While these covers tend to be a little pricey, considering they’ll prevent electrocution and serious damage to your generator, the higher price tag is definitely worth it.

Canopies

Canopies are an affordable option, however, they’re designed for temporary use only. You can easily construct your own canopy using a tarp, some bungees, and some rope, and poles. The tarp should not make any contact with the generator. You can even make do with a collapsible canopy designed for a day at the beach, just as long as the material is waterproof. The big downside here is wind. If it’s pouring rain and windy, the generator is going to get wet.

Tent Covers

A tent cover can also work and will help to maintain the generator’s portability. Tent covers can be purchased at any sporting goods store and may be one of the best options if you can’t find a generator cover. However, you won’t be able to really rely on these covers to protect your generator, in high wind conditions.

Permanent and Portable Generator Rain Shelters

An enclosure made out of steel is another popular option. These enclosures provide a much safer way to operate your generator and are usually on the pricey side. Of course, if you don’t have the right setup and you need a place to permanently house your generator, for emergency power, then you may also need to pour a pad of cement to support the enclosure, which can also be costly. This type of setup is perfect for the home, but if you’re looking for a portable option, this definitely isn’t it.

While a steel enclosure is the best option, if you’re looking for a more affordable enclosure, retrofitted plastic is also a good choice. However, there have been some reports that this type of enclosure can be potentially dangerous and can lead to overheating.

Make Your Own Generator Enclosure or Cover

Another option is to simply make your own generator enclosure. Most online tutorials that focus on DIY generator enclosures will teach you how to correctly vent the generator in order to avoid overheating or a possible fire.

You can also find tutorials that will teach you how to make your own generator cover, for half the price that a premade cover costs. These covers are usually made out of a thick tarp, combined with PVC pipes. For this type of setup, you’ll need to place the generator on top of a dry surface, such as a cement pad or a large piece of plywood. The key here will be to make sure that whatever type of enclosure you make, moisture and water is not able to find its way inside.

Remember:

  • The control panel and the outlets on a generator must be completely protected from moisture
  • Air circulation is crucial in order to prevent a fire or the generator from overheating.
  • If you plan on taking your generator with you on your next camping trip, make sure the enclosure you have is portable, or buy or make a generator cover.
  • Make sure the cover or enclosure can protect the generator in the event of both high wind and rain

What Type of Generator Should I Use During the Rainy Season?

Each type of generator is going to be susceptible to serious damage if you don’t take the proper precautions and keep the machine nice and dry during wet weather. However, a more compact, smaller inverter generator will be much easier to haul, transport, and protect from the elements.

Can You Put Gas in a Generator While it’s Running?

Always make sure you allow the generator to cool off before you refuel it. Otherwise, this can be very dangerous. If you pour gas into the tank while the generator is hot or running, the fumes can ignite. We recommend giving it twenty minutes of cooldown time before you add more gas to the tank.

Can I Run a Generator in a Shed?

A generator should never be used indoors, inside a traditional shed, or in a garage. Proper generator enclosures are carefully ventilated in order to circulate the air and prevent CO from building up. If you’re not sure the enclosure you’ve created is safe, purchase a CO detector, which will alert you immediately if dangerous levels of CO are detected.

Is it Okay to Run a Generator Without a Load

Running a generator without a load means the generator is operating without a building load. This can be done for a short period of time to ensure that the machine is in good working order. However, if done for an extended period of time, running the generator without a load can lead to wet stacking. When it’s run for a long time without a load, you will also waste a lot of fuel. Any unburnt fuel that accumulates on the exhaust stack can result in permanent damage.

As we mentioned, running a generator without a load should only be done to test the generator’s performance. If you don’t use your generator often, then this type of test should be performed at least once a year.
