Can You Run A Generator Overnight? – Precautions For CO And Noise

In this article, we have answered the question “Can you run a Generator Overnight” in detail by mentioning safety measures as well. Being campers and generator experts, our insights on the topic is valuable and authentic.

Yes. You can run your generator overnight, you have purchased it to provide continuous power. I have used my inverter generator overnight many times, but only during power outages, not regularly.

However, it is not a good idea to keep your generator running throughout the night until there is an emergency. There are safety reasons as well that we have to look at.

Different generators have different runtimes, a 12000-watt generator like Westinghouse wgen1200DF can last for 10 to 11 hours on a full tank at 50 to 60% load, whereas other wouldn’t last for that long.

Ultimately, it depends on the fuel efficiency and power output of the generator you are running.

Consider the following things, before you run your generator overnight

Can You Run Your Generator Overnight?

Can You Run A Generator Overnight

It depends on the model you are using. Most generators can run overnight under 50% load, and others can’t.

We don’t want to push a machine beyond its capacity. It will not only lessen the lifespan but can malfunction the machine as well.

So before purchasing any unit, check its runtime at 50% load to get an idea. Check our website for your desired generator, we have tested and written the runtime of most of the modern generators on the market.

Use CO Detectors

Carbon monoxide is an odorless, colorless, and poisonous gas that can cause multiple health issues including fatigue, headache, and nausea. It can even be fatal.

According to product Consumer Product Safety Commission, more than 900 people died of carbon monoxide poisoning emitted by portable generators “between 2005 to 20017”.

Modern inverter generators nowadays have built-in CO sensors to sense carbon monoxide concentration and automatically shut off the generator in case of danger.

If you are generator doesn’t have a CO detector, install one in your home or living area. CO is produced by many household items including portable generators.

Run Your Generator Properly:

Run your portable generator at least 20 feet away from the living area. I normally keep it 40 to 50 feet away, because I have a remote start model so I don’t have to get up and manually start it.

Federal agencies like CDC and CPSC offer guidance regarding portable generator use. You may check them too.

Always take the proper ventilation. An enclosed place can not only accumulate carbon monoxide, but it can overheat the generator and lead explosion.

Noise problem:

Apart from the above-mentioned risk problems, noise pollution is one of the biggest issues that can cause disturbance to you and your neighbors.

I always use a portable inverter generator that is rated at below 55dB while camping or tailgating, but not everyone has a quieter model.

So you would need either need a muffler or a soundproof box to suppress as much noise as possible. Fortunately, we have written a very good article explaining how to make a soundproof box using DIY techniques. Check that out.

Do Campgrounds Allow Portable Generators At Night?

Tent camping campgrounds don’t allow RV generators during night hours (from 10 pm to 6 am).

Can I leave A Generator Running Overnight In My RV?

If the generator is located at least 20 to 30 feet away from the RV, it is perfectly safe to sleep in an RV with all windows and doors closed.

But, you should install a CO sensor in the RV. We never know when carbon monoxide can sneak in.

How Long Can You Run A Generator Continuously?

Though most large whole house standby generators are designed to run for up to 3000 hours powering a medium-sized home, I would never recommend running it for more than 500 hours continuously.

It is ultimately a machine and it can overheat or malfunction due to continuous friction and vibration.

How Long Can You Run A Diesel Generator Without Stopping?

Many portable diesel generators can last for 48 hours to 72 hours before refueling. Depending on the choice of a standby generator, they can last for 500 hours before giving it a break if the fuel supply is continuous.

I am a passionate environment engineer, who has been in the solar, and inverter generator industry for years. I have been a part of multiple safety and environment-related courses such as IOSH, Fire Safety, Solid Waste Management, etc. I have been installing solar plants for residential purposes since 2018.
