Zoom on the Cat RP7500 E
In summary, the Cat RP7500 E is a portable generator especially useful for:
- Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
- Professionals who want to be able to deliver results, even during a power failure
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Cat RP7500 E is powered by a 420 cc OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 7500W as well as a peak wattage of 9375W.
This generator features a conventional pull-start mechanism, but also a convenient and easy-to-use 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).
The control panel includes the following 6 AC outlets:
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, as the RP7500 E holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.
The Cat RP7500 E has a conventional, open frame design, of the following dimensions: L32.9 x W27.4 x H24.7 in, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
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.
The RP7500 E's status and activity may be monitored conveniently via the control panel, as it features a convenient meter showing you voltage, frequency and lifetime hours. To offer you even more control and easy operation during night time, the panel is LED-lit.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), 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: oil, funnel and tool kit. An official storage cover is also available, as a separate purchase.
The Cat RP7500 E is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
Moreover, it features a spark arrestor and thus, may be used in forested areas.
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).
- As its weight is 207 pounds, the Cat RP7500 E falls in the expected weight range of the devices in the 7000-8000 rated wattage category. 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.
- The RP7500 E provides a higher run time than similarly powerful devices, reaching around 11 hours at 50% load. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the A-iPower SUA8000iSF, with around 13 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator reaches an estimated fuel consumption of 0.72 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you wish to further improve in the area of fuel efficiency, the A-iPower SUA8000iSF, which boasts with a gas consumption of only 0.52 GPH, may be the right generator for you.
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.
