Generator type: portable or standby?

6 Best Kohler Generators – Reviews of the Top Models from the BrandKohler allows you to choose between portable and standby generators. You must select the type that will work best for your particular needs.

Portable generators like the Kohler PRO7.5E are designed to meet the power requirements for job sites and camping trips. You can also use them for tailgating and similar mobile activities. They can be used to power appliances one at a time or simultaneously. However, you must be vigilant about not overloading the generator. They can run on natural gas, gasoline, or liquid propane.

On the other hand, standby home generators like the Kohler 12RESVL100 are perfect for backing up the power supply of the house. They are designed to be installed in connection with the main electrical system so they can automatically restore power in a matter of seconds. You will not even have to switch it on. There is no refueling required when it comes to standby generators. These generators can provide a large amount of power and can power critical hard-wired systems. The high-quality power delivered by Kohler standby generators will not cause any damage to your appliances.

How much power do you need?

When it comes to choosing a generator, the power output should take precedence over almost all other factors. You simply cannot invest your money in a generator that does not even meet your power needs. If you are planning to use your generator for heavy-duty purposes for long periods of time, then you must go for a model that offers 12Kw or more. These generators can be used to back up the power supply at your house and power multiple critically heavy appliances at the same time. On the other hand, if you know that you will only use the generator for recreational purposes, then you can settle for a model with lesser power output like the Kohler PRO2.8i. For standby models like Kohler 20RESCL-200SELS, you will not need to refuel.

How long you need to run your generator?

6 Best Kohler Generators – Reviews of the Top Models from the BrandStandby generators such as the Kohler 20RESCL-200SELS are designed in such a way that you will not have to refuel them constantly. Once the generator is in action, it will provide you with power until the electricity supply to your house is restored. However, portable generators are a different story because they come with a limited fuel tank capacity, which results in a limited runtime. You must have an idea of the duration of your usage so that you can choose a tank capacity accordingly. The Kohler PRO3.7E has a 3.4-gallon fuel tank and provides a run time of 9 hrs at 1/2 load, but the Kohler PRO2.8i has a smaller tank of 2.55 gallons and gives a run time of 6.7 hrs at rated load.

Safety features

Most KOHLER generators come with plenty of safety features so that users face no problems when using them. The low-oil shutoff feature ensures that the generator shuts down when there is a shortage of fuel and does not lay pressure on the engine. The overload prevention feature keeps the generator from causing accidents. When the machine detects too much load, it shuts down instead. The +/-1% voltage regulation in standby models like the Kohler 20RESCL-200SELS prevents unnecessary surges in the power so that your appliances remain undamaged. The power they provide has less than 5% harmonic distortion so that your sensitive appliances are protected. Portable models like the Kohler PRO7.5E have maintenance minders.

Tips and tricks

    • Make sure that you do not use the generator indoors for long periods to avoid toxic emissions.
    • Generators should always be kept in dry surroundings because moisture can corrupt the machine permanently.
    • Back-feeding a powerful generator can lead to accidents.
    • The filter must be checked at least twice a week and cleaned properly.
    • Refueling a generator when it is still hot is not a great idea and can also lead to unnecessary spillage.
    • If you are using a standby model, you must wire it into the electrical panel and fuel system of your house for an automatic response.
    • Always use high-quality, fresh fuel.

Kohler generator prices

Since Kohler offers different ranges when it comes to generators, it is only natural that they offer different prices.

Portable generators tend to com cheaper because they have a lower power output. However, if you want to carry the machine from place to place, then they are ideal for you.

FAQ

Kohler has immense faith in its products, and you should too. The company tries its best to put out products that are premium and functional. KOHLER generators are worthy investments, and it is unlikely that you will ever regret your purchase. Since the company believes in the quality of its products, it offers a good warranty offer for all its generators. All the standby generators come with a 5-year or 2000-hour limited warranty. This means that you will be able to avail the warranty at any point within five years of your purchase and before you use the generator for 2000 hours. On the other hand, the portable generators come with a 3-year limited warranty that you can avail without any problem. You can contact the company directly, or get in touch with the retailer from whom you bought the generator.

If you own an RV or recreational vehicle, then you should get your hands on a portable generator that will work in conjunction with the machine seamlessly. However, you should be aware that not all Kohler portable generators can connect to an RV directly because they do not have the necessary RV outlets. However, Kohler does carry portable generators that have RV power outlets that will allow you to link the RV with the generator directly. Make sure that you connect the wires properly, or else the setup might not work.

There is no reason why you should not be able to power your home with a portable generator. The primary advantage of a portable generator is that it can be carried from one place to another and be flexible in terms of usage. If you have the portable generator at home, you can hook up the different appliances with the machine separately and power them up. However, you will not be able to enjoy the advantages of a standby generator. When you install a standby generator in your house, it automatically starts working when the power is cut. The power is restored in the house in a period of 10 seconds, and you do not have to put in any effort.

Our Verdict

The Kohler PRO7.5E is a portable generator that runs on gasoline. It can provide a long run time of 12 hours because of the 8-gallon fuel tank. It has both an electric start and a recoil start. The maintenance minder feature is a boon because it keeps you up to date with every development. The generator allows users to make custom adjustments and is OSHA compliant. The Kohler 20RESCL-200SELS is a standby generator that can be powered by both natural gas and liquid propane. It is fuel-efficient but is able to restore power within 10 seconds. The resulting power output has less than 5% harmonic distortion. The Kohler PRO2.8i comes with a 2.55-gallon tank and is perfect for users who want a small and portable generator. At 1/4 load, the generator can provide a run time of 14.7 hrs.
