Can Portable Generators Run Continuously?

Can portable generators run continuously? The answer depends on several factors, including the fuel source used, the type of generator, and the fuel tank size. This article will explain the different types of portable generators available, how to choose the right one for your situation, and how to decide which ones will last the longest. Continue reading for more helpful tips on choosing portable generators. Whether you need a continuous or standby unit is up to you, and these tips will make the decision process much simpler.

Standby generators

A standby generator is designed to keep the power on in a home or business during extended power outages. These generators can run critical home comfort systems and equipment. “Doc” Dancer Heating & Air explains how long a standby generator will run and how to get the most out of it. Here are some tips to ensure that your standby generator is dependable and will last for many years. After installing your standby generator, check its status once a week.

The fuel used in standby generators depends on the type and size of the unit. Natural gas units can run continuously, while those powered by liquid propane will need to be changed every few days. Natural gas stands by as a better choice than liquid propane, but you will still need to check the size of your fuel tank. Luckily, most standby whole house generators come with enough LP fuel for a few days of operation.

Natural gas

Unlike the traditional diesel-powered portable generator, natural gas is able to operate continuously, even during power outages. This is especially beneficial when gas lines have been down for several days. But running gas lines is not an option for many homeowners, and they’re more expensive as well. Besides, diesel generators tend to be more resourceful, but their fuel tank capacity is limited and gas prices can be prohibitive.

Portable generators do not have a transfer switch and can run some appliances directly, like a furnace. Be sure to check the cords for fraying and three-prong plugs before you run them. However, you should avoid running any appliances such as a well pump or furnace on natural gas. Always check your generator’s manual to make sure that it has no dangerous components, and follow all safety tips.


Unlike wind and solar power, diesel generators can run continuously. These units are also capable of providing secondary power for utility grids. During peak demand periods or when large power generators are not available, these units can provide power. In the UK, the National Grid uses these units as part of its “STOR” program. It also provides power for peak-lopping situations and for export to the power grid. However, there is a downside to these generators.

High-speed diesel generators can provide considerable startup and operational benefits. On the other hand, these systems are not suited for prime applications, as the frequency of servicing and overhaul is high. In addition, their low reliability makes them unsuitable for many applications. Furthermore, they cannot be used in all weather conditions, such as in disaster recovery situations. In addition, diesel generators can only run continuously for 6 months. For such applications, a diesel generator should be sized according to the load requirements.

Fuel tank size

Before buying a portable generator, it’s important to consider the fuel tank size. The size of a fuel tank depends on how much time you expect to use the generator. A 12-hour tank may be 10-12 inches tall, while a 72-hour tank may be 36 inches tall. A twenty-four-inch difference could mean that you need to climb a step ladder to reach the controls and gauges. Or, you might prefer a permanent platform where you can easily access the control panel.

A generator’s fuel tank size is measured by how much fuel it can burn when it is fully loaded. This is an important factor, because it anticipates the worst case scenario. While generators are designed to operate at full load, they rarely operate at full capacity, so the fuel tank size should be determined accordingly. However, remember that this is an approximate value, and the actual run-time will be longer. A fuel tank size of four to eight gallons will usually be sufficient for a normal power outage.

Electrical demand

With the aging of the country’s power infrastructure and the rising cost of fossil fuel, the electrical demand for portable generators is expected to rise substantially. The U.S. is expected to hold the largest share in the portable generator market by 2021. Other major factors driving the growth of the portable generator market include the increasing number of weather-related disasters, rising urbanization, and improving living standards. By 2021, North America is projected to hold the largest share, accounting for over 85% of the global market.

Increasing population and poor grid infrastructure are factors driving the market for portable generators. Climate change is a growing concern worldwide, affecting weather conditions throughout the world. Frequent natural calamities are also disrupting energy supplies. Portable generators are an ideal solution for power outages and are a practical choice for remote locations. By providing reliable power to various tools, portable gensets are an excellent choice. But the demand for portable generators in the Middle East is forecasted to be at least USD 1.5 billion by 2021.
