Description

Zoom on the KOHLER PRO12.3EFI

In a nutshell, the KOHLER PRO12.3EFI is a powerful portable generator mostly geared towards 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 KOHLER PRO12.3EFI in use

The KOHLER PRO12.3EFI

The KOHLER PRO12.3EFI's core is the 694 cc KOHLER Command PRO® EFI OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 10500W and a peak wattage of 12300W.

Enjoying a noise rating of 79.9 dBA (less noisy than a dishwasher), this generator can be started thanks to a conventional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included). To add further convenience, the PRO12.3EFI can 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 fuel capacity of 8.7 gallons allows the PRO12.3EFI to operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.87 GPH). 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.

The PRO12.3EFI generates a clean sine wave: providing <5% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel includes the following 7 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle
120/240V 50A (SS2-50R) receptacle

Additionally, it features 1 DC outlet: there's a 12V 8A receptacle with which charging your batteries is made easy.

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, since the PRO12.3EFI 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 KOHLER PRO12.3EFI is a typical, open frame, with the dimensions of L35.2 x W22.4 x H30.3 in, offering support and stability and enabling the possibility of raising it above ground level. The featured design is ideal for the outdoors and all tough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 306 pounds. 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

Panel of the KOHLER PRO12.3EFI

The PRO12.3EFI's control panel

Monitoring of the PRO12.3EFI's status and activity is made possible by a digital data center, which provides information on the lifetime run hours and is one of the features of its control panel.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Sentry™ technology), giving you a peace of mind during use.

Regarding its accessories, besides the aforementioned features, the KOHLER PRO12.3EFI's box includes the typical documentation and an owner's manual (opens in a new tab), letting you start it right off the bat.

Emissions

The KOHLER PRO12.3EFI is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all 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).

  • A weight of 306 lbs makes the KOHLER PRO12.3EFI one of the heavier devices in the 10000-11000 rated wattage range. If weight matters to you, one of the champions in this power range is the A-iPower SUA13000EFI with only 218 pounds.
  • This generator, with its lowest possible noise rated at 79.9 dBA falls into the more noisy category, compared to other devise of a similar running wattage. If noise emissions are one of your priorities, you may be interested in the A-iPower SUA13000EFI, one of the least noisy generators similarly powerful as this one, rated for 69 dBA.
  • Given that the PRO12.3EFI reaches an autonomy of around 10 hours with a full tank and at 50% load, it is placed within the average autonomy range of similarly powerful generators. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Powerhorse 13000ES, which is able to run for around 15 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.87 GPH (gallon per hour) at 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.
