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 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. Honda EU7000iS is a perfect example of a powerful inverter generator on this list.

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. An exception here is the Pulsar PG7750B, which is more than fairly calculated for a dual-fuel model.

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 Honda EU7000iS has a running time of 18 hours at 25% load and utilizes only 5.1 gallons of fuel. Pulsar PG7750B is another excellent model with a running time of 13 hours at 50% load and fuel consumption of 6.6 gallons.

Available outlets

Averagely, every 7,500 Watt generator should have a minimum of five sockets so that you can operate four large devices or systems simultaneously. The Sportsman GEN7500DF is considered the most powerful Sportsman generator, has seven sockets, while Cat RP7500E has 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. The quietest generator on this list is the Honda EU7000iS. It generates only 52dB (A) of noise @ 25 percent load. Its sound is similar to the whispering of two people. If you don’t have too much equipment to run, this generator from Honda is a good choice. It’s expensive but lasts a lifetime.

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.


Our three best 7500 Watt generators available in the market today are the Westinghouse WGen7500, the Champion Power Equipment, and the Cat RP7500E.

The Champion generator is unique because it’s a dual fuel generator that can use either petrol or propane to generate electricity, which can be very helpful when you use your generator in different situations.

Also, the Champion generator has an in-built over-voltage protector that prevents you from damaging the engine by connecting too many devices. The Cat generator is designed for high power operation and has a large 8gallon fuel tank, but keep in mind that the fuel efficiency of this unit can be quite low.

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.
