Top 3 7500 Watt Generators on the Market

Westinghouse WGen7500

The Westinghouse WGen7500 is a powerful generator a maximum output of 9500 watts, the most impressive surge power of all 7500 Watt generators. Also, this unit is suitable for home use, for the operation of a mobile home or even for use on a remote construction site.

Users loved the electronic start, which eliminates the hassle of a standard recoil start, and the included remote control, which allows the machine to be started from inside the house or motorhome. The generator has a moderate fuel tank capacity of 6.6 gallons but is relatively fuel-efficient thanks to the 420cc four-stroke engine that sits in the middle.

At half load, the generator can work for about 11 hours on a single tank — a running time that only competes with the Cat generator, which consumes over a gallon more of fuel during this period. At the same time, this generator is the quietest with a noise level of only 73dB.

The main panel of the generator is full-featured and all sockets have removable covers to protect the generator. There are four standard 120V household sockets and one 120/240V twist-lock socket and a display panel that shows how much watts the generator is using and the estimated remaining running time.

However, there’s no 12V socket for charging batteries, no USB port for charging small electronic devices, and no socket for motorhomes where motorhome owners can easily install this generator. Westinghouse provides a three-year limited guarantee on the generator.

Pros

  • 11-hour running time and high fuel efficiency
  • Electronic start with supplied remote control
  • The display shows wattage and remaining running time
  • Three-year warranty

Cons

  • No 12V, USB, or motorhome sockets

Cat RP7500E

The CAT RP7500E Generator is just as suitable for tough use at off-grid construction sites as it is for home use. The 420cc OHV engine can produce a 9375W of peak power, although it should be noted that the fuel efficiency of this engine is not comparable to generators with four-stroke engines.

With a big fuel tank capacity of 8gallons, this generator operates for 11 hours at half load — more than many other 7500 watts generators. The generator is equipped with both electric start and a recoil start, which starts the engine each time within the first one to two pulls.

Also, the front of the generator has a small display where you can easily see how many watts you are using. Although Cat does not publish a rating for this generator, in terms of noise, users found it to be on par with other 7500 watts generators.

The sockets are strongly focused on standard and shop options and feature two 30-amp sockets for powering heavy tools and four standard 120V sockets for appliances.

Users, who took this generator to remote construction sites, appreciated the robust frame of this generator, which gets strong rubberized wheels that can easily drive over uneven terrain. Cat offers a three-year limited warranty on the generator.

Pros

  • 11 hours running time
  • Electric and recoil start
  • Display of wattage and runtime
  • Two 30 ampere socket
  • Three years warranty

Cons

  • Poor fuel efficiency and large dimensions due to an enlarged fuel tank

The Briggs & Stratton 30664 8000W Generator is an advanced version of its predecessor with 25% more power output, allowing you to run large devices simultaneously. Its 420cc 2100 series OHV engine is protected in a powder-coated cast iron sleeve that enhances its performance.

The generator is equipped with a 7.5-gallon stainless steel fuel tank, which continues to run for 9hours at a 50% load. Its loud operating noise is one drawback of this model, but it’s still better than its predecessor.

The model’s multifunctional control panel allows you to easily interchange between five different power outlets, including one lockable 120/240V 30A outlet and four GFCI 120V household outlets. All is covered with a rubber sleeve to protect them from extreme weather conditions, such as strong winds, rain, and heat.

It comes with two large 2-inch Never Go Flat wheels and a foldable handle for easy movement inside and outside the house. Because it is compact, you can take the generator with you when camping in the woods.

Also, it features a three-year warranty for private households and a 90-day limited commercial warranty on parts and labor.

Pros

  • Higher power output lets the generator run longer
  • Five outlets for the simultaneous operation of three to four large appliances
  • Sockets are GFCI-protected
  • Compact, easy to move
  • Two-year housing guarantee and 90-day commercial warranty

Cons

  • A loud mechanism that can wake up children
  • Not CARB compliant

HONORABLE MENTION: Simpson Cleaning SPG7593E

The Simpson Cleaning SPG7593E Generator is loved for its powerful electric production, but have some problems with its noise level, which makes it more suitable for use on a remote construction site than in a residential area or motorhome.

The generator can produce a 9300-watt peak power, which is equivalent to the performance of competing for 7500-watt generators. However, while most generators in this category release less than 80dB of noise, this generator has over 95dB of noise when in operation.

The waveform of the current it emits is relatively loud, making it best for power tools than for sensitive electronics such as household appliances and computers. Apart from that, this generator is impressed in terms of fuel efficiency and range of socket it offers.

The generator has just a 6gallon tank capacity and can still run for up to eight hours at half load. The socket panel contains two lockable 30A sockets in addition to the four standard 120V sockets. Note, however, that there’s no 12V DC outlet for charging the battery.

The devices weigh over 200 pounds, although it was designed to be wheeled around easily. And it can be difficult to move on and off a truck for transportation. Also, home users receive a standard three-year warranty, while commercial users are limited to a one-year warranty from Simpson.

Pros

  • Good fuel efficiency
  • Two 30A locking sockets

Cons

  • Noisy
  • Not supplied with a battery

Important Features to Consider When Selecting a 7500 Watt Generator

Every 7,500 Watt generator you want should be equipped with certain features that make it efficient and long-lasting. It must meet your requirements and legal regulations so that you don’t have to bother replacing it with another model later.

Here are eight important features to consider when buying a 7,500 Watt generator:

Generator Type

You’ve got the choice between traditional and inverter generators, which are less noisy than the former. You can change the load and further reduce the noise. However, they are not on the cheaper side.

There’s another choice you have to make — single fuel and dual fuel. As you might expect, dual fuel generators are more expensive, but they’re preferred as some models let you switch between fuels.

Rated power and maximum output power

The higher the maximum power output, the more devices and tools your generator can start at the same time. Keep in mind that some tools and equipment have a much higher starting power than when in operation. However, purchasing a generator with a higher rated and maximum output power is of no use if it has a short running time.

Reliable engine

Search for a generator with not only a powerful engine but also a reliable and fuel-efficient one. It must have protection from harsh weather conditions with a sleeve made of stainless steel or powder-coated cast iron. The engine is the heart of your generator, so clean it regularly, even when it’s not in use.

Fuel tank capacity and running time

Buy a generator that uses the least amount of fuel runs the longest. Ideally, it should for a range of nine hours so you can sleep through the night without having to wake up to refill the tank at dawn.

The Westinghouse WGen7500 has a running time of 11 hours at 50% load and utilizes only 6.6 gallons of fuel. The Briggs and Stratton 30664 is another excellent model with a running time of 9 hours at 50% load and fuel consumption of 7.5 gallons.

Available outlets

On average, every 7,500 Watt generator should have a minimum of five sockets so that you can operate four large devices or systems simultaneously. The Cat RP7500E would be a great example of this as this generator includes six sockets.

Start system

In this modern era, there’s no reason to pull a recoil system and hurt your backs when starting the generator. All models mentioned on this list have an electric start with a recoil backup. The Westinghouse WGen7500 is even equipped with remote control, so you don’t even have to touch the generator to start it.

Noise level

The lower the noise level, the quieter you and your family will sleep at night. Unfortunately, the 7,000 Watt model generators are not the most quiet, usually ranging within 60-80 dB. The 2,000-5,000 Watt models are typically more quiet.

Size, weight, and portability

If you use your generator only occasionally to provide power to your house during a power failure, portability is unlikely to be at the top of your list of important features of your generator. However, if you take your generator with you when you travel, power your motorhome, etc., size and weight must be considered.


Conclusion

In our opinion, the three best 7500 Watt generators available in the market today are the Westinghouse WGen7500, the Cat RP7500E and the Briggs & Stratton 30664.

We believe that the Westinghouse generator is the best 7500 Watt generator overall because of its low noise level of 73 dB, an impressive 9500 Watt surge power along, and the promise of a lifetime of Westinghouse technical support.
