Description

Zoom on the KOHLER PRO9.0E

In summary, the KOHLER PRO9.0E is a portable generator especially useful for:

  • Food truck owners and people participating in outdoor fairs, festivals or events
  • Professionals who want to be able to deliver results, even during a power failure

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 PRO9.0E's core is the 429 cc KOHLER Command PRO® OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 7200W and a peak wattage of 9000W.

The generator is rated for a noise of 78.2 dBA (less noisy than a shower). Its starting mechanisms include a simple traditional pull-start mechanism and a convenient and easy-to-use electric starter (battery included).

With a fuel capacity of 8 gallons, the PRO9.0E may run for around 11 hours at 50% load with a full tank (fuel consumption around 0.73 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 PRO9.0E is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<6%).

Several examples of what the generator may allow you to power simultaneously are:Note: All of these devices might not start simultaneously. Provided examples are based on a maximum load of 75 % and estimated wattages. With the help of our wattage calculator you can find out if this product suits your requirements.

Outlets

The control panel features the upcoming 6 AC outlets:

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

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

Even though this KOHLER generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, due to the featured twist-lock L14-30R receptacle, the PRO9.0E is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The design of the KOHLER PRO9.0E is a typical, open frame, with the dimensions of L29.4 x W21.4 x H22.3 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.

Since the generator weighs 218 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). Never less, it can still be moved quite conveniently with the help of a wheel kit (⌀10") and a folding handle, once it is placed on the ground.

Features

The PRO9.0E's control panel

Monitoring of the PRO9.0E's status and activity is made possible by an illuminated data center (Maintenance Minder), which provides information on the lifetime run hours and is one of the features of its control panel.

In addition to this info, a light indicator allows you to instantly see if the oil level is too low.

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.

Besides the usual set of documentation and user manual to get you promptly started, KOHLER also included a battery charging cables in the PRO9.0E's packaging.

Emissions

The KOHLER PRO9.0E is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

The KOHLER PRO9.0E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the KOHLER PRO9.0E compare to generators of similar power (between 6500 and 7500 W).

  • Considering its dry weight of 218 pounds, the KOHLER PRO9.0E is one of the heavier generators producing between 6500 and 7500 running watts. In terms of weight, one of the champions in their power range is the Lifan LF7250, standing at just 140 lbs.
  • This generator, with its lowest possible noise rated at 78.2 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 Lifan ESI 7000iER-EFI. With just 59 dBA, it is one of the most quiet devices in this power range.
  • The PRO9.0E provides a higher run time than similarly powerful devices, reaching 11 hours at 50% load. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Pulsar PG7500B, boasting with 13 hours.
  • 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 In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.73 GPH. If you wish to further improve in the area of fuel efficiency, the Lifan ESI 7000iER-EFI, which boasts with a gas consumption of only 0.38 GPH, may be the right generator for you.

Price comparison

As you can see from this dynamic chart, when compared to other 6500-7500W generators, the KOHLER PRO9.0E 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.
