Generac is a company whose name you can unquestionably trust when it comes to generators.

Be there a requirement of a backup generator for homeowners, powering tools for businesses or standby power systems for large data centers and resources and tools, Generac has always been serving well its customers with the great quality of their products across the globe.

The power segment of the generators we consider today is the 7000+ Watt rating division, and our product of examination today is the superb Generac GP7500E (Model 5943).Generac GP7500

The generator has a power rating of 9375 Watt for surge power and 7500 starting power.

Of course, generators in this power range aren’t portable but definitely come with wheels, which is why taking it places isn’t that big a problem.

The build is solid and sturdy, and the price range is also quite affordable. Before we get into the review, we suggest you watch this YouTube video first, and then come back to read further details and analysis.

Design, Dimensions & Weight

The appearance of the product is quite decent – no complaints about that.

One can easily spot the fact instantly that it is a Generac product because of the orange-black colours used in the conventional Generac products.

The cradle for the unit is made up of hardened 1 ¼” steel cube, making it even more durable and potently assembled.

The wheels used are solid 9.5” heavy duty ones without tubes so that they never go flat, no matter how harsh the surface underneath gets. Thus, portability here is of great convenience.

Coming to the dimensions; sticking to the L×B×H regulation, the measures are 27.25”×27”×25” inclusive of the frame – pretty cubical in terms of proportions.

Now, one thing to remember is that the design comes with a fold-down extended handle for easy porting the unit.

This owns bonus points to the product for the extremely enhanced convenience of movability it gets the consumer. This extended length of the generator is 44.5”. What we mean to say will be clear to you from the image below:Dimensions

With the extended handle being praised about, we now talk of the weight of the product. The Generac GP7500E weighs 191.5 pounds – heavy, yes, but with the architecture at its best, we don’t really regard this as a problem.

Weight being one of the most basic factors in determining the credibility of a product; we compared a lot of models for weights.

If you’re looking for a great lightweight model in the given power range, we definitely recommend you to check this model out.

Power Output/Generation

Generac’s 420cc OHV engine with 3600 RPM and splash lubrication technology ensures a longer life for your generator’s engine. The unit comes with single touch electric start for trouble-free start up with batteries.

In addition to all these features, the model includes low oil shutoff which automatically shuts the engine down and safeguards it against all kinds of damages.

For the output generation, the Generac GP7500E has a rating of 9375 surge watts and 7500 continuous watts.

Now, there is a lot of confusion among the audience as to what continuous and surge watts are, and why one should consider them as important parameters while deciding the product they want to purchase.

Well, here’s what they mean.

Continuous or running power is the power that is required to operate your power equipment continuously, without interruption.

Surge power, however, is the extra power that an appliance requires for its start up, though, instantaneous.

For example, your refrigerator might have a power rating of 1100 Watt, but when starting it up, it’ll pull, maybe, 2200 Watts to begin with its operation.

For power output, it is completely up to you to decide one according to your suited needs. Here is where this one stands among others.

Fuel and Noise

Generac 5978 GP7500E 7500 Running Watts/9375 Starting Watts Electric Start Gas Powered Portable Generator - CSA Compliant

Noise levels are of great concern to a lot of consumers of these generators.

The company itself has not published any sort of official data for measuring noise levels, but from what we saw and observed, it is approximately 70-72 decibels.

Yes, the noise levels indeed are a little high, but for a 420cc engine giving a power output of 7500 Watt, it is justified.

There are specific points and cautions to be kept in mind before and while filling the generator up with fuel. Always remember never to fill the tank indoors, and not to spill gasoline on hot engine, or when the engine is running.

This can be extremely dangerous.

While adding the fuel, do not fill the tank up to the brim. Always leave some space in the tank for fuel expansion. If fuel tank is overfilled, the fuel can seep into the hot engine

The fuel to be used in the model should be regular unleaded gasoline. Do not use premium gasoline, or gasoline mixed with oil.

There should be no additives to the fuel you select. Use of any other fuel might damage the generator entirely, and where you will not be able to claim warranty in this case.

So, it is always recommended to use only the recommended fuel by the company.

For Californian consumers, the generator is not built to serve them. The Generac GP7500 is not CARB compliant and does not meet the specifications and regulations in terms of emissions.

So the product loses marks in this aspect.

The runtime on full tank at 50% load capacity as specified by the company is 11 hours. This, we think is pretty impressive for the unit rated 7500 watts and that too, at half the capacity.

If the load is decreased, the duration would increase even more by a couple of hours. Speaking now of the tank capacity for the model; it is 28.4 litres, or 7.5 gallons, as specified by the company, which is great because you wouldn’t have to worry about refueling the unit repeatedly.

A large tank ensures extended hours of use, and so, the capacity for the Generac GP7500E is definitely something to boast about.

More the fuel capacity, less often do you have to refuel your generator. The unit stands quite well above a lot of models in this respect.

Table: The model has a pretty good fuel tank capacityGenerac GP7500E Fuel Capacity

There are a lot of consumers to whom noise is the prime most factor in deciding which generator they want to buy. Noise-wise, the generator doesn’t win the segment, but stands mediocre.

Table: The unit is moderately noisy, going by the decibel levelsGenerac GP7500 Noise

More the operation hours, more preference the generator gets. If the operation hours are more, you don’t have to worry about the generator dying out unexpectedly. Here, again, the generator stands moderate among the lot.

  • Allow the engine to run at zero load for a couple of minutes to stabilize the internal temperatures of the unit.
  • Move the switch to off position.
  • Close the fuel valve.

Additional Features

There are always some features in every product that make it better than a lot of generators in the market. Here are some that make this one stand out of the rest of the crowd:

Covered Outlets: The receptacles are covered with plastic wraps to protect the outlets from dusty environments and rugged operating conditions.

Fold-down Handle: The folding handle makes the carrying of the generator easier in a lot of ways. The handle enhances the portability making it sturdier and easier compact storage.

Warranty/Repairs

The warranty would be applicable right from the date of the original sale. For claiming the warranty of the product, you will be expected to produce the original proof of purchase to the service dealer.

Please ensure that all warranty repairs must be claimed only by an authorized and certified Generac dealer.

The parts that have been resold or will not be covered under the warranty and use of non-Generac parts used in the generator will entirely void the manufacturer’s warranty.

Along with this, there are certain cases and exceptions where the warranty will not be applicable. We are listing those below:

  • Cost of regular maintenance and repairs.
