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
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 simple traditional pull-start mechanism and also a simple and elegant electric starter (battery included).
The RP7500 E can operate for around 11 hours at 50% load with a full tank (fuel consumption around 0.72 GPH), due to its fuel capacity of 7.9 gallons.
The control panel features the following 6 AC outlets:
This Cat generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor. Besides, since the RP7500 E bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.
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 device has been designed for tough environments and demanding outdoor use.
As the generator's weight is 207 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). 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 control center features a convenient meter showing you voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity. To offer you even more control and easy operation during night time, the panel is LED-lit.
Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.
From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.
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, tool kit and funnel.
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 and therefore, can 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).
- Since the generator weighs in at a dry weight of 207 lbs, the Cat RP7500 E belongs in the expected weight range for devices which can produce between 7000 and 8000 rated watts. Regarding dry weight, one of the champions in the same power range is the Sportsman GEN85KIDF, with a dry weight of only 133 lbs.
- With a run time of around 11 hours at 50% load, the RP7500 E has one of the higher run times, compared to its similarly powerful peers. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the A-iPower SUA8000iSF, as it provides around 13 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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 fuel consumption is your top priority, we suggest to check out the A-iPower SUA8000iSF, which has a fuel consumption of only 0.52 GPH and thus, is one of the most efficient devices in our database.
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.
