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

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 RP6500 E in use

The Cat RP6500 E

The Cat RP6500 E's design includes a gasoline-fueled 420 cc OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 6,500W and also a peak wattage of 8,125W.

This generator can be started via a simple traditional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included).

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

Outlets

The control panel features the upcoming 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle
120V 30A (L5-30R) receptacle

Even if this Cat generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle. Besides, since the RP6500 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.

Portability

The design of the Cat RP6500 E is a typical, open frame, with the dimensions of L32.9 x W27.4 x H24.7 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough environments and demanding outdoor use.

Since the generator weighs 202 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). However, this lack of maneuverability is compensated by its wheel kit and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Cat RP6500 E

The RP6500 E's control panel

The RP6500 E's status and activity may be monitored conveniently via the control panel, as it features 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.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

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: tool kit, oil and funnel. An official storage cover is also available, as a separate purchase.

Emissions

The Cat RP6500 E 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 therefore, can be used 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).

  • Having a dry weight of 202 lbs, the Cat RP6500 E belongs in the expected weight range for generators which produce 6000 to 7000 rated watts. If weight matters to you, one of the champions in this power range is the Pulsar PGDA70BiSCO with only 118 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. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Pulsar PG7500, reaching 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. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.66 GPH. 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

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.

    • Always started first pull.it ran for 10 days straight except fuel and maintenance 2 different times with no problems.
    - CONS:
    • None to report. It preformed better than I expected.
