Description

THE BEST CHOICE WHEN THE JOB CALLS FOR POWER. This powerful, but still very portable generator is good for any light industrial use whatever the location and when you need a lot of power in a small footprint. Provides many hours of service, even when powering multiple items. Cat portable generators are equipped with electric starters and lithium ion batteries that automatically recharge whenever the generator is running. Our power will be ready when you are. We’ve designed our portable generators with your safety in mind. Recessed sockets and snap - fit protected covers keep vital connections between your valuable devices and the generator protected. We’ve also installed ground fault circuit interrupters (GFCI) that shut off the power if it detects an issue in order to keep you safe. (source: Cat (opens in a new tab))

Zoom on the Cat RP7500 E

In a nutshell, the Cat RP7500 E is a portable generator mostly geared towards:

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Professionals who want to be able to deliver results, even during a power failure

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Cat RP7500 E in use

The Cat RP7500 E

The Cat RP7500 E's engine, 420 cc OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 7500W and reaches a peak wattage of 9375W.

This generator features a conventional pull-start mechanism, but also a simple and elegant electric starter (battery included).

The fuel capacity of 7.9 gallons allows the RP7500 E to operate for around 11 hours at 50% load with a full tank (fuel consumption around 0.72 GPH).

Outlets

The control panel provides the upcoming 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle
120V 30A (L5-30R) receptacle

Even though this Cat generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, because the RP7500 E is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

The dimensions of the Cat RP7500 E, which are L32.9 x W27.4 x H24.7 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 207 lbs make it incredibly difficult to manually lift and transport. Nevertheless, thanks to its wheel kit and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the Cat RP7500 E

The RP7500 E's control panel

The RP7500 E and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity. To offer you even more control and easy operation during night time, the panel is LED-lit.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Cat RP7500 E also comes with several accessories, including: tool kit, oil and funnel. An official storage cover is also available, as a separate purchase.

Emissions

The Cat RP7500 E is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, so it is adequate for use in forested areas.

Product Video

The Cat RP7500 E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Cat RP7500 E compare to generators of similar power (between 7000 and 8000 W).

  • With a dry weight of 207 pounds, the Cat RP7500 E finds itself in the expected weight range for generators able to produce between 7000 and 8000 rated watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Sportsman GEN85KIDF, with a dry weight of just 133 pounds.
  • Thanks to an impressive running time of around 11 hours at 50% load, the RP7500 E benefits from a higher run time than many generators of a similar output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the A-iPower SUA8000iSF, boasting with around 13 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. Standing at an estimated 0.72 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the A-iPower SUA8000iSF. With a fuel consumption of as little as 0.52 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 7000-8000W generators, the Cat RP7500 E is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
