Zoom on the KOHLER PRO12.3EFI
In summary, the KOHLER PRO12.3EFI is a powerful portable generator especially useful for professionals who want to ensure that a power failure will not prevent them from working.
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.
Power & Run Time
The KOHLER PRO12.3EFI
The KOHLER PRO12.3EFI is powered by a 694 cc KOHLER Command PRO® EFI OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 10500W as well as a peak wattage of 12300W.
The generator features a simple traditional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 79.9 dBA (less noisy than a vacuum cleaner). For additional convenience, the PRO12.3EFI may also be remotely started (separate purchase).
The Electronic Fuel Injection (EFI) system enhances the engine's reliability, lowers fuel consumption, improves startup, reduces servicing, boosts stale fuel resistance, and offers better altitude adaptability.
The PRO12.3EFI can operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.87 GPH), due to its fuel capacity of 8.7 gallons. Refilling the fuel tank is facilitated by KOHLER’s Accu-Fill™ technology. It offers a 45% larger angled fuel inlet, which allows for an easier and safer pouring of gasoline as well as less spilling.
Sensitive electronics can be safely plugged in the AC outlets, as the PRO12.3EFI produces a clean sine wave, with a <5% Total Harmonic Disruption (THD).
Outlets
The control panel includes the following 7 AC outlets:
Furthermore, it has 1 DC outlet: there's a 12V 8A receptacle allowing you to easily charge your batteries.
This KOHLER generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, due to the featured twist-lock L14-30R receptacle, the PRO12.3EFI is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.
Portability
With its dimensions of L35.2 x W22.4 x H30.3 in, the conventional, open frame design of the KOHLER PRO12.3EFI offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.
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 306 lbs. Nevertheless, thanks to its wheel kit (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.
Features
The PRO12.3EFI's control panel
The control panel of the PRO12.3EFI includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the lifetime run hours.
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 (Oil Sentry™ technology) and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
Along with the aforementioned features, from an accessory standpoint, the KOHLER PRO12.3EFI's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly.
Emissions
The KOHLER PRO12.3EFI is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
The KOHLER PRO12.3EFI versus other generators
The following charts are provided to give you an idea of how some of the key specs of the KOHLER PRO12.3EFI compare to generators of similar power (between 10000 and 11000 W).
- As its dry weight is 306 pounds, the KOHLER PRO12.3EFI is one of the heavier of the products which can generate 10000 to 11000 running watts. If weight matters to you, one of the champions in this power range is the A-iPower SUA13000EFI with only 218 pounds.
- When compared to devices able to produce a similar running wattage, this generator and its lowest emitted noise of 79.9 dBA is on the noisier side. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the A-iPower SUA13000EFI, whose lowest noise levels reach just 69 dBA.
- Offering around 10 hours of running time on a full tank at 50% load, the PRO12.3EFI is within the average autonomy range of similarly powerful generators. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Powerhorse 13000ES, as it provides 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. At an estimated fuel consumption of 0.87 GPH (gallon per hour) at 50% load, this generator is a rather fuel efficient one within its wattage category. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.78 GPH, the A-iPower SUA13000EFI is a device you should look out for.
Price comparison
As you can see from this interactive chart, when compared to other 10000-11000W generators, the KOHLER PRO12.3EFI is on the expensive side of the price range.
While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.
