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
- Prudent homeowners who want a backup power source in case of a power outage
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 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.
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 simple and elegant electric starter (battery included). To add further convenience, the PRO12.3EFI can be remotely started (separate purchase).
Thanks to a fuel capacity of 8.7 gallons, the PRO12.3EFI can 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 produces a clean sine wave: thanks to a <5% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.
The control panel provides the upcoming 7 AC outlets:
Furthermore, it has 1 DC outlet: there's a 12V 8A receptacle with which you may charge your batteries with ease.
Even if this KOHLER 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, 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.
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 design is ideal for rough environments and demanding outdoor use.
Since the generator weighs 306 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, its challenging mobility is solved by a wheel kit, which will ease its displacement, once it is on the floor.
An illuminated data center, one of the features of the PRO12.3EFI’s control panel, gives you information on the lifetime run hours, and thus, is helpful for the monitoring of its activity and status.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Sentry™ technology), allowing you to use it with a peace of mind.
Regarding its accessories, besides the aforementioned features, the KOHLER PRO12.3EFI's box includes the typical documentation and a user manual, letting you start it right off the bat.
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).
- Considering its dry weight of 306 pounds, the KOHLER PRO12.3EFI is one of the heavier generators producing between 10000 and 11000 running watts. In terms of weight, one of the champions in their power range is the A-iPower SUA13000EFI, standing at just 218 lbs.
- 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. For those who are looking for a less noisy device, we suggest the A-iPower SUA13000EFI. With just 69 dBA, it is one of the most quiet devices in this power range.
- The PRO12.3EFI provides a higher run time than similarly powerful devices, reaching 10 hours at 50% load.
- 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 At an estimated fuel consumption 0.87 GPH (gallon per hour) at 50% load, this generator is a rather fuel efficient one within its wattage category. If you wish to acquire one of the most gasoline efficient products of this power range, the A-iPower SUA13000EFI, with a fuel consumption of 0.78 GPH could be in your good books.
As you can see from this dynamic 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.
The bottom line
- Remote start capable
- Clean sine wave
- High run time
- Fuel efficient
- On the expensive side
- No spark arrestor
- On the heavy side (306 lbs)
- On the noisy side (79.9 dBA)
