How Long Do Standby Generators Last?

how long do standby generators last

Whether you have a diesel or propane burning portable generator, it is important to know how long it will last. There are some steps you can take to ensure that your unit is properly maintained, but it is also a good idea to invest in a few things that will help it last longer.


Using a standby generator to keep your home powered up when the power goes out can be a relief. These units are hardwired to your home, which means they’ll automatically kick on and run until the power comes back on.

Depending on the unit you choose, you can expect to have power for up to four days. However, with proper maintenance, your Generac generator can last even longer.

Most portable generators only provide a short amount of power before they stop running. Because of this, you need to maintain them to keep them running for a long time.

If you have a permanent standby generator, you can use natural gas instead of diesel. The advantage of using natural gas is that you don’t have to worry about gas line problems.


A standby generator’s longevity can vary depending on many factors, but there are some general guidelines to follow. Some of the best standby generators will be built to last for as long as your home’s needs require. This includes both natural and liquid gas types.

The life-span of a standby generator is determined by the quality and maintenance of its components. These include the alternator, battery, and fuel tank. During normal use, a good standby generator should be able to operate for approximately 15,000 to 30,000 hours without hassle. However, the longevity of a standby generator can decrease as demand increases. For instance, power outages can interfere with your daily activities, resulting in lost productivity and possibly even health issues.

Most standby generators are equipped with a two to three day LP fuel tank. Proper storage and handling of liquid propane are important. While propane is a fuel that is generally considered to be safer than gasoline, it can still be dangerous if not handled properly.


Having a diesel standby generator is a great way to get the power you need at the moment you need it. These generators can last for decades. However, they need to be maintained. If you keep up with maintenance, you can extend the life of your generator.

The life of a diesel standby generator depends on a number of factors. Some of them are the size of the engine, the amount of time it is used, the frequency of use, and the environment it is installed in.

You should also take into consideration the fuel. A diesel generator uses more fuel than a gas generator, so you’ll need to refill it more frequently. It’s also more expensive.

The lifespan of a diesel standby generator can be extended if you take care of it. A generator with a high quality brand name usually guarantees a longer useful lifetime.

Propane-burning portable generators

It is often hard to decide what type of fuel to use on a portable generator. Many people are opting for propane. This fuel is a great alternative to gasoline.

Propane has the advantage of being a clean burning fuel. Unlike gasoline and wood, it produces no carbon monoxide. As a result, there is less risk of explosion. However, propane has less energy density than gas and diesel. So the question is how long do propane-burning portable generators last?

While it is true that propane generators are more expensive than their gas-powered counterparts, they do offer a number of advantages. Among these are reliability and a wide variety of uses.

Depending on the engine used, propane generators are capable of providing a good amount of power. In addition, propane has a wide shelf life.

Preventive maintenance

If your business needs a backup generator, you should make sure you have a maintenance schedule in place. This is a critical way to avoid unnecessary repairs. A faulty generator can cause downtime, resulting in losses. Also, it can be a safety hazard.

Generators are an essential part of many businesses. They can help businesses operate smoothly and efficiently. However, they are subject to wear and tear. Taking the time to maintain them regularly will ensure they last as long as possible.

There are a number of different factors to consider when implementing a maintenance plan. First, you need to understand what your generator is capable of. Next, you must identify the environment your unit will be operating in.

For instance, if your location has a harsh climate, you need to make sure your generator is in a good, clean condition. You also need to account for rain and debris.
