7500 W Generator Buying Guide

Fuel

You’ll find 7500-watt generators that run on different fuel types. The most popular ones are propane, natural gas, diesel, and dual-fuel – though not necessarily in this order. 

You’ll want to look at this aspect to anticipate how clean the generator will burn and how economical it will be. 

Propane

Propane generators are the best choice for eco-conscious buyers. The safest type of fuel for the environment, it burns cleanly, and it stores well in tanks of various sizes for extended periods. 

It’s an option that sellers handle easily and conveniently, meaning you’ll be able to order it and will arrive at your place without complications. Once you have it, you can keep it for a long time without worries. 

However, the main drawback of propane is that it burns fast. The burn time varies depending on the wattage of the generator. It is estimated that a 15-kilowatt generator will take around 2.8 gallons of propane per hour. A 7.5-kilowatt one will take approximately 1.3 gallons per hour. 

Because they take up a lot of fuel, propane 7500-watt generators are not the most practical choice. But they do work well for remote sites, where you may not have access to other types of fuel. 

Natural Gas

Natural gas is a non-renewable resource, yet it is also one of the most effective and most affordable fuel types in this category. Efficient, cleaner, and less expensive than other non-renewables, it burns without a pungent smell. 

It also significantly reduces costs when used to power a home. And anywhere in large cities, since it travels through pipelines, it makes a readily-available resource. This last advantage, however, has an obvious downside: you can’t store it on-site. 

What’s more, natural-gas-powered generators will typically manifest a delayed start time. For operations that can’t stand even the smallest temporary interruptions, this is a drawback you need to be well-aware of. 

Natural gas generators directly compete with diesel models. Because they burn cleaner, with lower emissions, and because they are less expensive, they seem to be the better choice – at least in areas where you have direct access to a gas pipeline. 

Diesel

Diesel generators are, by far, the most common choice for standby applications. This type of fuel is readily-available, reliable, and easy to store on-site. What’s more, it has a kick-in time without rivalry, another edge over the natural gas models. 

Because of all these benefits, 7500-watt diesel generators are perfect for backing up critical functions in easily accessible or remote sites. Standby applications and emergency backups are where you’ll commonly find a generator with diesel fuel. 

The disadvantages of working with diesel are not that many. While it stores well, if you’re planning on keeping it for extended periods, you’ll have to take extra steps to make sure it maintains its quality. 

Plus, such generators have higher emissions and can fail to pass EPA standards. 

Efficiency-wise, a diesel generator will burn, on average, 1.5-gallons with every hour of operation. 

Dual Fuel

With dual-fuel units, you’re getting the best of natural gas and diesel. Flexibility is, by far, the biggest strength of choosing this type of fuel. They also have lower emissions than generators that run exclusively on diesel. Consequently, they easily meet the EPA standards. 

Nevertheless, bi-fuel is far from being a standard type of fuel. Quite many of the prominent manufacturers don’t offer this option among their 7500-watt generators. 

So, while this idea might attract you, there’s a high chance that you won’t find dual-fuel generators from your favorite brand.

Fuel Tank Size

The fuel tank size is often correlated with the run-time. In theory, the larger the tank is, the longer the run-time. It makes sense if you think that a larger tank means it can store more fuel, and it can burn for longer. In practice, this equation is influenced by fuel efficiency. 

As shown above, some fuel types burn faster than others. Like natural gas compared to diesel. Or propane compared to… anything else. So, for the average 7500-watt generator, gas-powered, you’ll typically get a 6 or 6.5-gallon tank. Occasionally, you’ll also find options around 8 or 8.5 gallons.

Starting System

You’re getting two main options: the pull start and the electric start. If you have the chance, go for a 7500-watt generator with electric start and recoil backup. 

The pull start is also known as recoil, rewind, or manual start. It implies using sheer force, pulling the recoil cord to start the engine. It’s generally more affordable and doesn’t need special maintenance. 

Still, the recoil start requires a particular strength and a learning curve. Not everyone can make it work from the first try, which can be frustrating when using the generator for an emergency

By contrast, the electric start is much simpler to operate, as you have to push a button to turn on the generator. Electric start comes with a battery that you will most likely have to charge regularly. 

The only way the electric start will fail you is if you allow the battery to drain. Such generators are more expensive, and the top-of-the-range ones will automatically recharge the battery while they run.

Noise Level

Most generators of this wattage score a noise level between 70 and 80 dB. The size of the motor directly influences the noise. Since there are no significant size variations among the 7500-watt models’ engines, noise levels aren’t too different. 

Nevertheless, manufacturers use specific design details, like adding mufflers and other parts that can help reduce the noise level. Quiet generator is considered anything around 73 dB.

Portability

Portability is given by the size and the weight of a generator, yet multiple design details can enhance it. Wheels and a handle – ideally a foldable one – are a must, considering that generators have large tanks built-in that add extra weight. 

A 7500-watt portable generators can still weigh around 200 lbs, though, as long as it sits on wheels, it shouldn’t be hard to maneuver. What’s more, you must consider portability related to how often and where you’re planning on using it. 

If it’s for occasional operation and mostly in the same place, you don’t have to obsess about portability. If you need it on-site and you’ll use it a lot, portability becomes critical. 

Speaking of which, some manufacturers add frames to make them easier to carry around. Note that frames add weight, too – if you are carrying it up and down stairs or lift it in a truck, you don’t want that extra weight.

Pricing Range

Because 7500-watt generators have a wide range of applications, they are in high demand and available in both average and highly-priced versions. Many will be around $1000, with the most expensive ones going even at $1500. Occasionally, you might find a good quality, cheap 7500-watt generator at about $850.

Frequently Asked Questions

Q: How Much Can a 7500 Watt Generator Run?
A:

For the most 7500-watt generators, the run-time at half-load is somewhere around 8 hours. The most efficient ones can run even up to 11 hours. Half-load means half of the rated wattage. It’s an average measurement chosen because there are too many factors influencing the run-time. 

Briefly, the run-time reflects how long the generator will run with a tank of fuel. This value is a consequence of the fuel tank size, fuel efficiency, and motor efficiency. A larger tank may run less than a smaller one when it relies on a fuel that burns faster. 

Equally important, the wattage you draw from it will significantly impact the overall efficiency of the generator. Running it at full capacity, by plugging an appliance in each of its outlets at the same time, will make it run much shorter than only using one outlet at a time.

Q: What Will a 7500 Watt Generator Run?
A:

From small devices and batteries to all the appliances you have in an RV, a 7500-watt generator can run many different items. 

At home, you could use it for a standard refrigerator with a freezer, a 1000-watt microwave oven, and a water heater at the same time. That’s because all these items have a total running wattage of approximately 6500 watts. 

To determine what your generator can run, you must sum the running wattages of the appliances you intend to plug on its outlets. If you’re getting less than 7500 watts, you should be able to run those appliances simultaneously. 

For general guidance, consider that the highest consumer is usually the dryer, with 3000 watts. It’s followed by a fridge with a freezer (700 watts of running power, 1200 watts at peak), and a washing machine (500 watts of running power and 1400 watts at peak). 

Everything else, however, is under 1000 watts. A laptop or a TV takes 300 to 400 watts, a coffee maker, a toaster, or a microwave more like around 800 watts.

Our Verdict

A reliable 7500-watt generator will handle most of the common appliances and gadgets you would run at home. And it can also make the right choice for construction sites. 

If you manage to find a less noisy model – because generators are quite loud by definition – and you get a manufacturer that backs it up with a solid warranty, you shouldn’t think twice about getting it. 

In the end, you’ll make a brilliant choice by taking two extra factors into account: how much power you’ll want to draw from it AND which type of fuel will best suit the operating conditions. 

All the technical details are described above. Just go ahead and connect the dots to see what applies to you!
