Zoom on the KOHLER PRO12.3EFI
In a nutshell, the KOHLER PRO12.3EFI is a powerful portable generator mostly geared towards professionals in need of safely powering high-intensity work or lighting equipment.
Power & Run Time
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 is rated for a noise of 79.9 dBA (less noisy than a shower). Its starting mechanisms include a conventional pull-start mechanism and a simple and elegant 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.
With a full tank, the PRO12.3EFI can operate for around 10 hours at 50% load (fuel consumption around 0.87 GPH), thanks 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.
The PRO12.3EFI generates a clean sine wave: providing <5% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.
The control panel features the upcoming 7 AC outlets:
Furthermore, it has 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.
The KOHLER PRO12.3EFI has the following dimensions: L35.2 x W22.4 x H30.3 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
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, it can still be moved quite conveniently with the help of its wheel kit, once it is placed on the ground.
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 fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Sentry™ technology), which gives you a complete peace of mind when using it.
As for its accessories, apart from the previously mentioned features, the KOHLER PRO12.3EFI also comes with the basic documentation and an owner's manual (opens in a new tab), allowing you to start it right away.
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.
- If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 79.9 dBA can be considered somewhat noisy. 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.
- 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. 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.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. This generator, with an estimated fuel consumption of just 0.87 GPH (gallon per hour) at 50% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. 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.
