Engine-Generator or generator is an equipment used for providing power to other appliances. It converts mechanical energy to electrical energy and offers electric power to several different devices. In case the electric grid fails and there is no electricity for the entire day, then the generator is beneficial. You can also use it to power the corded electrical tool. But the question arises ‘How long can a generator run continuously?’ In this article, you will get the answer to this question and also detailed information about it.
How Long Can a Generator Run Continuously?
Before answering this question and getting further information about this, it is better to know about the factors which affect the generator’s running time.
The ﬁrst important factor is its fuel capacity. Most generators use gasoline to produce power. You can get the maximum run capacity by deriving the fuel consumption rate. This is because the fuel capacity depends on the amount of power you utilize. This thing will give you an idea of how long the generator will run.
Most of the time, you will ﬁnd the maximum runtime in the product features. But on average, you can run a generator continuously for anywhere between 7.5 hours to 12 hours. The period varies for different models and depends on other factors also. Here are some examples of generators along with their run time:
- Westinghouse WGen3600v: 18 hours
- DuroMax XP4000S: 8 hours
- Champion 3800-Watt Dual Fuel: 9 hours
- Briggs & Stratton 30676: 14 hours
- Rainier R2200i: 13 hours
The larger generators can even work for 24 hours continuously and can be used as a source of electricity backup for the homes. On the other hand, small generators don’t have the potential to run for 24 hours non-stop. But Stanley 5000 Watt All-Weather Generator is an example of a generator that can run for the entire day.
Runtime For Portable And Standby Generators
There are two types of generators available- One is portable, and the other is a standby generator. They are divided based on their capacity of running i.e., the duration for which they can run continuously. In case you are using a portable generator with a good amount of propane fuel, then it can run for up to 200 hours, or about eight days. This is because portable generators are designed for a limited runtime.
While using a standby generator with a good supply of fuel, then it can run for 500 hours, or 21 days at a time. Standby generators have large and more efﬁcient motors used mainly for long-running hours. You can run a portable generator for a few hours and cannot refuel it while running. This is because it is a dangerous task and may cause the generator or gasoline tank to burst into ﬂames.
In the case of the standby generator also, you have to remain careful while running it for long hours. It is because the generator and other appliances are at the risk of getting damaged. So, you have to allow the engine to cool down after the long hours of running. Also, you need to perform necessary maintenance before turning it on again. This will increase the life of the generator and its engine.
Fuel Consumption Capacity Of Generators
Fuel Consumption Capacity is an essential factor that affects the runtime of the generator. Some generators use propane, diesel, or natural gas to generate power, but mostly you will ﬁnd that they use gasoline. This factor depends on other aspects, as well.
The fuel consumption capacity depends upon the efﬁciency of the engine, power output capacity, and the amount of power used. The larger 5000-watt gas power generators can consume up to 0.8 gallons of fuel within an hour while the smaller ones use up to 0.3 gallons’ fuel per hour. For the entire day, you have to arrange around 20 gallons of fuel for larger ones and about 7 gallons for small generators.
Lifetime of Generators
The lifetime of generators is usually estimated based on its engine and usage. The powerful engine can work for years and provide quality results. Also, reasonable usage can further extend the life of the generator. Proper maintenance is a must after using it for a long time. The manufacturer provides the guarantee of the number of years you will be able to use it. The power generators usually come with two or three years limited warranty. You can also follow the instructions to extend its life.
Most of the portable generators can last for a much longer time than mentioned by the manufacturer. It can last up to twenty-thousand hours. But it varies for different models. If you don’t use the generator for a more extended period, then it can efficiently work for twenty years. In case you run the generator constantly for days, then you have to replace it within a couple of years.
The generator can run continuously for many hours, but it depends upon several factors. The fuel consumption capacity, the life of the engine, the daily usage, and the proper maintenance are important aspects affecting the capacity of a generator to run continuously.
You can use portable generators to power your house or shops when there is a power outage. They can run for a limited time, which is due to its fuel capacity. They are designed to run for about 8 to 12 hours at a time. They have a lifetime of up to 20,000 hours at 1/2 load. On the other hand, standby generators have the potential to run for long hours continuously. They also have large fuel capacity and can run for 500 hours in a single go.
