Description

A GREAT SOLUTION FOR LIGHT COMMERCIAL OR RESIDENTIAL NEEDS. This electric start generator, is a good option for keeping your business or home up and running. 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. A single-side, LED-lit panel contains all of the power outlets and controls in one intuitively-designed location, including the start/stop switch, choke, and fuel shutoff switch.

Zoom on the Cat RP6500 E

In a nutshell, the Cat RP6500 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 who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals who want to ensure that a power failure will not prevent them from working

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 RP6500 E in use

The Cat RP6500 E

The Cat RP6500 E's core is the 420 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 6500W and a peak wattage of 8125W.

Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery included).

The RP6500 E can operate for around 12 hours at 50% load with a full tank (fuel consumption around 0.66 GPH), due to its fuel capacity of 7.9 gallons.

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

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, as it features a twist-lock L14-30R receptacle, the RP6500 E is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The Cat RP6500 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. 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 202 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 RP6500 E

The RP6500 E's control panel

The control panel of the RP6500 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.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Cat RP6500 E, the following accessories are also included: funnel, oil and tool kit. An official storage cover is also available, as a separate purchase.

Emissions

The Cat RP6500 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, which makes it suitable for use in forested areas.

Product Video

The Cat RP6500 E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Cat RP6500 E compare to generators of similar power (between 6000 and 7000 W).

  • At a weight of 202 pounds, the Cat RP6500 E places in the expected weight range of the generators in the 6000-7000 rated wattage range. If weight is your top priority, one of the champions in this power category is the Sportsman GEN85KIDF, weighing just 133 pounds.
  • With a run time of around 12 hours at 50% load, the RP6500 E has one of the higher run times, compared to its similarly powerful peers. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Generac XC6500E, which is able to run for around 14 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.66 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the A-iPower SUA7000L. With a fuel consumption of as little as 0.36 GPH, it is one of the most efficient generators currently on the market.

Can this generator run your home a/c and other small appliances at the same time? (Asked June 09, 2020)

Considering that it is recommended to not exceed an 80% load, this unit can run for 5200W (6500*0.8) worth of appliances at the same time. While this should normally be plenty for what you mentioned, you'd need to know the actual wattage needs of your own a/c and appliances. Feel free to use our wattage calculator to help you assess your power needs, as it allows you to add custom appliances.

is it rain proof (Asked August 28, 2021)

The unit should be properly sheltered. We recommend reading our article on generator operation in bad weather.
