Zoom on the Cat RP7500 E
In a nutshell, the Cat RP7500 E is a portable generator mostly geared towards:
- Food van owners who know that just a short power outage could lose them hundreds of dollars
- Homeowners in need of an emergency backup power for their essentials
- Professionals in need of safely powering high-intensity work or lighting equipment
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Cat RP7500 E's engine, 420 cc OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 7,500W and reaches a peak wattage of 9,375W.
This generator can be started thanks to a simple traditional pull-start mechanism, but also to 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:
While this Cat generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with 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. This type of design is ideal for tough environments and heavy outdoor use.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 207 pounds. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.
The control panel of the RP7500 E includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity. To offer you even more control and easy operation during nighttime, the panel is LED-lit.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Cat RP7500 E, the following accessories are also included: tool kit, funnel and oil. An official storage cover is also available, as a separate purchase.
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, making it usable 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).
- At a weight of 207 pounds, the Cat RP7500 E places in the expected weight range of the generators in the 7000-8000 rated wattage range. 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.
- As the RP7500 E features an autonomy of around 11 hours at 50% load, it has a higher run time than an average generator of its power range. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 9000, reaching around 13 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. As this generator uses an estimated 0.72 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.55 GPH, the Pulsar PG10000B16 is a device you could look out for.
