Zoom on the Cat RP12000 E
In summary, the Cat RP12000 E is a powerful portable generator especially useful for 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 RP12000 E's core is the 670 cc Rato OHV V-Twin engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 12000W and a peak wattage of 15000W.
Its starting mechanism is based on a simple and elegant electric starter (battery included).
The RP12000 E can operate for around 11.7 hours at 50% load with a full tank (fuel consumption around 1.13 GPH), due to its fuel capacity of 13.2 gallons.
The RP12000 E generates a clean sine wave: providing <5% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.
The control panel includes the following 8 AC outlets:
It also sports 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle with which you may charge your batteries with ease.
Even though this Cat generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, as the RP12000 E 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.
The design of the Cat RP12000 E is a typical, open frame, with the dimensions of L35.7 x W32.7 x H35.8 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.
While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 350 lbs. 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.
A lift hook located on the top of the frame offers an additional safety feature while facilitating the transport, loading and unloading of the generator.
The RP12000 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 night time, the panel is LED-lit.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Cat RP12000 E's package also includes these accessories: battery charger, tool kit, oil and funnel.
The Cat RP12000 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 RP12000 E versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Cat RP12000 E compare to generators of similar power (between 10000 and 14000 W).
- With its weight of 350 lbs, the Cat RP12000 E is one of the heavier generators in the 10000-14000 rated wattage category. In terms of weight, one of the champions in their power range is the A-iPower SUA13000EFI, standing at just 218 lbs.
- With a run time of around 11.7 hours at 50% load, the RP12000 E has one of the higher run times, compared to its similarly powerful peers. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Powerhorse 13000ES, with around 15 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 is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 1.13 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the A-iPower SUA13000EFI, which has a fuel consumption of only 0.78 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 10000-14000W generators, the Cat RP12000 E is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
