How Long Do Generators last?

Make sure to do regular maintenance on your generator, such as changing any oil filters and oil, during periods of inactivity to ensure you get the most out of your generator. In addition, replace the starter plugs and air filters. These techniques ensure that you get the most out of it.

The majority of portable generators have a runtime of 95 to 105 hours. Different models produce different results, so check the manufacturer's website or the product packing for details. Because the oil in diesel engine generators might deteriorate, they last longer. However, they necessitate larger filters and oil tanks, increasing the time used.

Oil checks should still be done regularly, especially if you frequently use this generator type. To maximize capabilities, be careful not to put in more oil than the machine requires and know how long power outages last in your location. With good maintenance, these machines will run for a total of 195 to 205 hours per use.

What to Lookout for When Buying A Portable Generator

1. Outlets and Power

The first step in choosing the best generator for your needs is figuring out how big you need it to be. That means you'll have to figure out how much power you'll need. What happens if your refrigerator only needs 700 watts to run, but it needs 2100 watts to startup?

Consider the startup watts required to power the equipment you intend to connect to the generator, as well as the "running watts" required once everything is up and running. A few 120V AC outlets and USB connectors are common on smaller inverter generators.

When you approach 4000 watts, you'll notice that there are more 240V plugs and 120V outlets. So if you want an electrician to connect your generator directly to your electrical panel, you'll need a 240V plug. Also, because your generator is used outside, be sure it includes GFCI outlets (Ground Fault Circuit Interrupter).

2. Total Harmonic Distortion (THD)

The waveform is important if you plan to run electronic devices like laptops or lab equipment. It is advisable to aim for a total harmonic distortion of less than 6% to avoid harming electrical circuits. It's also known as "clean power" or "pure sine wave," and it's a more steady and predictable voltage level.

Pure sine wave generators are more expensive and can be found in lower-wattage devices. By the way, not all battery inverters have low THD. Some produce square waves. If you know you'll require clean power, look at the specifications.

3. Is it used regularly or only on occasion?

Most generators come with a consumer warranty that covers you for several years. Any reputable brand will work for emergency power or leisure use. If you require a generator regularly, you want to seek a model with a commercial engine. Not only will it fit better, but you'll probably get a warranty that lasts longer than 90 days or 6 months. The obvious disadvantage is that they are usually more costly.

4. Fuel Type

Gas generators are by far the most popular fuel type. Use a gasoline stabilizer to counteract the effects of ethanol, whether you're keeping fuel in the tank or in fuel containers. Diesel generators offer superior fuel efficiency if you're ready to spend the extra money. You'll also get rid of the carburetor, which appears to clog up at the most inconvenient times.

Diesel is the way to go if you're looking for a whole-house generator. However, consider that diesel isn't always as easy to come by as gasoline. A propane or gas generator that can be converted to propane use is another alternative. It's another option if you want to use a more environmentally friendly fuel source and don't mind it being a little more complicated.

Battery-powered inverters offer the benefit of recharging via solar panels, running quietly, and emitting no pollutants. The disadvantage is that they're pricey, take a long time to charge, and normally only provide about 2000 watts of power. As a result, they're currently not a very practical alternative outside of camping.

5. Fuel Tank

You can go longer between refuelings if your fuel tank is larger. Most generators have a fuel tank capable of providing 7–9 hours of operation at 50% load. If you use a lower fraction of the available power, you'll run longer; if you use more, you'll go faster. Plastic and gas fuel tanks are also available. Plastic is the preferred material because it does not rust.

6. Starting

If you can afford the extra expense, electric start engines are fantastic. However, when buying a portable generator, you'll see that most of them still use lead-acid batteries like those found in cars.

However, some lithium-ion ones are circulating. Before using, make sure your battery is fully charged. Most generators will be fine if the battery charger is left plugged in between usage to retain the charge.

7. The Level of Noise

A silent design is available for smaller generators. However, by the time you reach the 4000-watt level and upwards, there isn't much left in the "quiet" category. The fuel source is one thing to think about. Diesel engines make significantly more noise than comparable gas engines.

8. Electronic Fuel Injection (EFI)

EFI does away with the use of a carburetor. Clogged carburetors are one of the most common problems for folks who do not maintain their generators as well as they could. In addition, your generator will be easier to start in cold weather.

9. Detection of Carbon Monoxide

Carbon monoxide (CO) detectors are included in the generators of several manufacturers. These merely monitor the amount of carbon monoxide around the engine and turn it off if the levels become too high. They usually operate faster than the ones you can put in your house and are more effective at preventing CO-related illness or death. However, be aware that CO detectors can be tampered with. To avoid erroneous readings, make sure the generator exhaust is pointed downwind from the sensor and not in a corner.

10. Kit for Wheels

Although generators are large and heavy, not all of them come with a wheel kit. Some stores ask you to purchase it individually, so double-check before you swipe your credit card! Generators with two or four wheels are available. In addition, you can buy aftermarket generator dolly kits to add wheels to a model that doesn't have them.

11. Hook Bar Lift

If you're purchasing a portable generator for commercial or industrial use, you'll almost certainly need to move it to a higher floor at some time. A generator with a raised hook bar provides a significant advantage that can save you time and effort.

Frequently Asked Questions(FAQs)

1. How Do I Connect a Generator to My Home?

The ability to connect your generator directly to your home is a very practical way to have emergency electricity. However, the best option is to utilize a whole-house backup generator designed expressly for that purpose. When the electricity goes out, these whole-house generators turn on or off automatically.

Of course, they're more expensive than portable ones, but they've recently gotten more reasonable. Many portable generators can also be connected to your home. However, they, like whole-house generators, are not do-it-yourself projects. You'll need to hire a professional electrician to install the transfer switch.

There are many additional factors to consider. The first step is to ensure that the generator you select has sufficient power. When you don't have enough power to run the whole house plus starting surge, you may need to prioritize by tripping some breakers. If you're using a portable generator, be sure you know where it'll be sitting while it's operating and that you have enough wire to reach your transfer switch.

2. What is the maximum amount of time a generator can run on 5 gallons of gasoline?

When you need to run standalone equipment that requires a lot of power, generators are necessary. Different types and sizes of generators consume gas at varying rates. Some will run for 8 hours, while others run for nearly twice as long. Some are also only good for 2 to 4 hours and use less gas.

Most manufacturer and expert recommendations for using generators state that they should not run for more than a few hours. Maintenance, gasoline, and grease are required more frequently for internal components. To save resources when you need them most, utilize the generator sparingly with periods of inactivity in between.

3. Can I Use a Generator Throughout the Night?

You're in luck if there are any reasons why you might want to leave a generator running in the middle of the night while you sleep. Such a task is safe and achievable if a few recommendations are followed. First, remember to set the alarm for the times when it will be active and to check on it first thing in the morning.

Fill your generator to the utmost capacity and double-check that it can run for an extended amount of time. Get a CO detector and keep an eye on the levels when using it. Make sure the generator is kept in a soundproof area, as it can be quite noisy when attempting to sleep. Finally, as generators are highly expensive and easy targets for theft, make sure they are stored in a secure location.

4. How Should I Store My Portable Generator?

It's critical to drain the gasoline from your portable generator before storing it for more than a month. Gasoline is not only acidic, but it also begins to break down after 30 days, making it more volatile and inefficient. To ensure that nothing is left in the engine after draining the gasoline, it is necessary to run the carburetor dry.

5. What Gas is Used in a Portable Generator?

A non-diesel portable generator runs on unleaded gasoline with an octane level of 87 or higher. It's also a good idea to add a stabilizer to your gasoline before starting your generator to keep it from overheating. The stabilizer will help protect the engine's moving parts from the corrosive effects of gasoline. The optimum ratio, and the length of its action, will be determined by the directions on the stabilizer container.

6. When and Where should Your Generator be Used?

Never use a generator inside or in the garage. Carbon monoxide is produced by the combustion engine of a portable generator. Therefore, it would be best if you only used your generator outside, away from any windows and doors, in a well-ventilated location.

During severe weather, never use your generator or leave it outside. Rain, snow, or other damp conditions can corrode your generator's metal components and cause catastrophic damage to its electrical components.

Conclusion

The Generac GP8000e is designed to be a multi-tasker. As a result, it is adaptable enough to serve a variety of objectives. In addition, it is the portable generator for you if you need something that can work in various settings.

A contractor might want a heavier-duty model, while someone who frequently takes RV vacations might prefer something lighter and quieter. A good generator is a significant investment. The Generac GP8000E series allows you to meet all of your demands with a single investment rather than having to spend more on numerous other types of generators.

The battery, which the engine cannot charge, is the only severe flaw. It means it must be removed when the engine is turned off. Hence charging the battery is more difficult than it needs to be.

Apart from that, the Generac GP8000E series is a user-friendly and convenient generator. The control panel is simple, portable, and equipped with shielded plugs and an hour meter for maintenance reminders.
