Description

THE PERFECT MULTI-USE GENERATOR. This handy generator brings all of the power you need to take care of both play and home needs. Versatile enough to run your motorhome's microwave, fridge, fans, and TV or keep your home's fridge, freezer, washing machine, security system, and water heater working. We've designed our portable generators with your safety in mind. Recessed sockets and water protected covers keep vital connections between your valuable devices and the generator dry. 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. All the vital information you need to operate your portable generator in a single display: voltage in use, frequency (Hz), current runtime in hours and total hours ran.

Zoom on the Cat RP5500

In a nutshell, the Cat RP5500 is a portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals who want to ensure that a power failure will not prevent them from working

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 RP5500 in use

The Cat RP5500

The Cat RP5500 houses a 300 cc OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 5,500W along with a peak wattage of 6,875W.

The generator features a simple traditional pull-start mechanism.

With a full tank, the RP5500 can operate for around 15 hours at 50% load (fuel consumption around 0.53 GPH), thanks to its fuel capacity of 7.9 gallons.

Outlets

The control panel features the upcoming 5 AC outlets:

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

As the RP5500 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.

Portability

The Cat RP5500 has the following dimensions: L32.9 x W27.4 x H24.7 in. In combination with its conventional, open frame design, they provide support and allow 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 178 pounds. Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

Panel of the Cat RP5500

The RP5500's control panel

To help you monitor the RP5500's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours. To offer you even more control and easy operation during nighttime, 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.

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 RP5500, the following accessories are also included: funnel, tool kit and oil. An official storage cover is also available, as a separate purchase.

Emissions

The Cat RP5500 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

Product Videos

The Cat RP5500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Cat RP5500 compare to generators of similar power (between 5000 and 6000 W).

  • Having a dry weight of 178 lbs, the Cat RP5500 belongs in the expected weight range for generators which produce 5000 to 6000 rated watts. Regarding dry weight, one of the champions in the same power range is the Genmax GM6000XiE, with a dry weight of only 106.9 lbs.
  • As the RP5500 features an autonomy of around 15 hours at 50% load, it has one of the highest run times in comparison to the other generators of its power range.
  • 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. Standing at an estimated 0.53 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 you are concerned with gasoline efficiency, having a fuel consumption of just 0.36 GPH, the A-iPower SUA7000L is a device you could look out for.

The bottom line

STRENGTHS:
  • Illuminated control panel
  • Several accessories included
  • GFCI Outlets
  • High run time
AVERAGE SPECS:
  • Decent weight (178 lbs)
  • Decent fuel efficiency
WEAKNESSES:
  • No electric start

What are the red brackets mounted from the engine to the frame for? Why does it say to take off and discard? Can I keep them to reinstall during transport? If I leave them on for normal operation will it mess up generator, void warranty. Please note, I have not started the generator with red brackets still on engine. (Asked October 11, 2020)

These brackets are for additional stabilization during shipping/transport. They should be removed as indicated, as continuously running your unit with them still on could, according to CAT, cause damage to the unit.

Is my cat rp 5500 water proof? If it gets wet with rain in the outside will it get damaged? (Asked June 11, 2021)

The unit is not waterproof and should not be operated in the rain. We recommend reading our articles on generator operation in bad weather and generator safety.
