Generator Storage Cover

Sharing is caring!

You have likely spent a small fortune on your generator so it only makes sense to have a generator storage box or some other type of generator storage for your investment. Storing or operating your generator indoors is not a good idea. As well letting it sit outside exposed to the elements is equally a bad idea.

In this article I’m going to go over “how to safety store your generator outside” I’m also going to look at “4 generator storage options”, “preparing a generator for storage” and “keeping your generator in top working condition” so it’s always ready to serve you when you need it. I’m also going to look at “is it a good idea to operate a generator in a storage Shed?”

How to Safety Store Your Generator Outside

Generator storage ideas can range from a homemade enclosure constructed out of wood which can also be locked to secure your generator from unauthorized use and theft. Other options can be a heavy duty canopy designed to withstand the elements. There are also various types of generator covers that allow the generator to be operating while covered.

The Importance of Safe Generator Storage

Having a generator during a power outage can provide basic power for lighting and keeping your appliances running so any food in your fridge and freezer doesn’t go to waste. The generator storage you choose needs to protect your generator from rain, snow and moisture build-up that can cause engine failure and damage.

Buy a Shed or Build

You may need to run your generator during an extreme weather event and it must be somewhere that’s not going to put your home at risk from exhaust fumes. As well most larger generators are quite loud, so having a secure place that will muffle some of the noise is ideal.

What Types of Options Are There?

Fortunately there are quite a few good options and will work for most any type of generator. If you have a generator that’s odd sized there are many universal storage options to look at. That may not be necessary as there’s lots of brand specific generator storage options you can get.

Generator storage options can be a small watertight shed that you buy or something that you can build yourself. I like the canopy styles as they offer various materials and many designs so I’m sure you’ll find something that will work for your generator.

Is a Generator Storage Option Right For Your Generator?

With the many options you’re going to want to be sure that it’s compatible with your generator. Even with the universal types make sure that it’s going to be a good fit with yours. Also make sure it’s made from good quality materials that will give you years of good service.

How to Prepare Your Generator For Storage

Having a generator is really handy and most of the time it will just sit, however when its needed you’ll want it to fire up and provide that needed power during an outage. Storing you generator correctly will mean it’s there to serve you. When a mayor storm takes out power lines you don’t want to start playing around with your generator then, that’s why proper storage is necessary.

Short-Term Generator Storage

Not much is needed if it’s only short-term and you know you’re going to be using it a few times, you’ll need to check the oil and keep the fuel tank full. Keep it clean and store it where it’s going to be fast access, that’s pretty well all you need to do for short-term storage.

Long-Term Generator Storage

You’re done using your generator and it’s time to put it away for long term, there are two things you’ll need to do before putting it away.

– Maintenance… Begin by cleaning the outside and then get out the owner’s manual for instructions for maintenance. You keep your car maintained so you should keep your generator maintained so it will be ready in the event of an emergency situation.

– Fuel Treatment… There’s always the option to run the generator dry so there’s no fuel in it, I don’t like this option for two reasons. One… If you need to use the generator in an emergency situation you have to get the gas and try and start it, which is usually must harder. Second… All the lines and gaskets tend to dry out making it harder to start as well.

Ryans Sheds Plans

My recommended choice is to treat the fuel with a stabilizer, this allows the fuel system to be full and prevents any moisture from getting into the system and keeps the lines and gaskets lubricated keeping the system full means you’re ready to start when you need it, no looking for fuel, just start and run.

If you’re going to treat the fuel, fill the tank and add the stabilizer and then start the generator and let it run for a few minutes. This will ensure the stabilizer has distributed throughout the entire fuel system. I recommend you get some “STA-BIL Fuel Stabilizer” for your generator and add some to your gas can too. You can check it out on Amazon here.

Keeping Your Generator in Top Working Condition

The bigger more commercial generators are diesel powered, while the generators most home owners will be using are gasoline powered. There are some generators that run on propane and natural gas, but the majority use gas. Just like any other gas powered device there is upkeep to ensure it will always be ready to supply you with power when needed.

Most people who buy generators are not mechanics, and most purchases take place after a major event and folks want to be ready for the next power outage. Here are a few reasons that can cause your generator to fail you:

– Not Running Generator… When you buy a generator or have it shipped to your home you need to unpack it and add or check oil and fuel and start it up.

– Not Broken In… Generators require a break-in time before they will give peak performance; some require the oil changed after the first few hours. Take the time to read the owner’s manual and follow the instructions for breaking-in your new generator. This will ensure it will give you many years of trouble free service.

– Bad Gas… Using old gas that’s been sitting around for months is the biggest cause of generator failures. Make sure you use fuel stabilizers to keep the fuel fresh when you’re going to be storing your generator for long periods of time. If you simple just use it and when the power comes back on and then store it without treating the fuel you may find that it will not start when you need it again.

Insuring Generator Reliability

Once you receive the generator carefully unpack it and do an inspection to make sure nothing is damaged. Follow the break-in instructions. If you find any issues with the generator now’s the time to contact the manufacturer for instructions to get warranty work done.

It’s a good idea to get into the habit of running your generator every month or two to keep it well lubricated and ready for use. Remember to use a good quality fuel stabilizer in the fuel.

Is it a Good Idea to Operate a Generator in a Storage Shed?

The short answer is NO. Generators produce carbon monoxide when there running which is poisonous; as well there is a high risk of a fire starting when used in closed quarters not to mention the noise level.

Storage sheds are excellent for storage and working in, however they have very poor air circulation because of their lack of windows that open and are not constructed to the same standards as your home.

So, Why Not Use a Generator in Your Shed?

The main reason is “carbon monoxide” also known as the silent killer, a generator gives of heat and the fuel it uses is highly explosive and in a closed space especially with dust if your using the shed for a shop, not to mention are highly noisy.

If you’re working in your shed you know the air quality is not the best and using a dust mask can help with the poor air quality. In the summer and early fall you can leave the door open, but in the winter you’re not going to want to leave the door open. The dust and gasses emitted by the generator will remain in the shed creating a very dangerous mixture.

The Risks of Using a Generator in Storage Shed

– Carbon Monoxide… Being odorless it can give you headaches, cause dizziness and eventually death. Most homes are required to have a carbon monoxide detector in them for that reason.

– Fire… Your generator provides fuel, oxygen and the means to ignite these. Manufacturers have stringent guidelines to follow and many warnings on their devices, but they can’t control what the user will do once they take the generator home.

If you’re using the shed for woodworking there’s going to be a lot of sawdust and small pieces of debris around and if you’re storing your generator in the shed without a cover it’s going to be covered in this dust as well. If your generator has a small leak of oil than that can also contribute to the fire risk.

Heat that your generator creates can also be a fire risk, some generators have sparks that come out of the exhaust and if you’re using it in a dry area outside you may want to consider adding a spark arrestor to the exhaust. The generator will have hot surfaces that can a burn injury if you accidentally come into contact with them.

– Noise… The noise that a generator emits is quite loud and the larger generators are louder. If you’re using a smaller inverter generator then the noise levels would be less. These inverter generators are good for camping or running a small appliance, they don’t have the wattage that the larger generators have for powering several appliances.

While there are things you can do to quiet down the generator it adds cost, one option would be to add a muffler to the generator which will help. In general using a generator inside a storage shed or garage is NOT a good idea. You can check out the full line of generator muffler kits here on Amazon.

I found this video that will drop the decibels of your generator by 10 points for next to nothing.
