But because different machines have different capabilities, it is even more important to go for a system that meets your exact needs and offers good value for money. Below is a comparison of ten popular generators model with a final verdict on which one of them is capable of providing efficiency and reliability.

Why Do You Need A Whole House Generator

Power blackouts are sometimes unpredictable. They happen when you least expect and you may have to compromise on your quality of life or schedule if such an occurrence is reported in your neighborhood. That’s where a whole house generator comes in handy.

It provides you with much-needed power so that you can complete all your important tasks before powermen can restore their systems. People buy these generators in order to guarantee seamless operation either at home or at work.

Kohler 20RESAL-SA7 20,000 Watt (Air Cooled) Generator – Our Top Choice

Kohler 20RESAL-SA7 20,000 Watt (Air Cooled) Generator

This standby generator is designed to automatically kick in whenever there is a blackout promising to restore your power is as little as 10 seconds. Kohler 20RESAL-SA7 boasts a 5-year limited warranty or an alternative of 2,000-hour warranty whichever elapses first.

The massive generator has outstanding motor-starting power, great power quality, and corrosion proof enclosure among other features.

Features:
 

  • Powerful and reliable motor powered with hydraulic valve filters and PowerBoost technology which accommodates larger electrical loads.
  • Has low distortion (THD), a feature that is needed to protect your sensitive electronics at home.
  • It operates quietly, all thanks to its advanced silencer technology which reduces sound levels and provides quiet operation at 69 dB(A) from 7 Meters
  • Has a built-in Ethernet and there is no additional hardware needed to make it safe for changing physical conditions. In addition, it has a pack of LED lights which allow you to view ATS status.
  • Meets EPA regulations for phase 2 small off-road engines and CA 2011 requirements.

PROS:
  • Relatively quiet and friendly for most neighborhoods
  • Easy to install, and it has two holes in front and back for easier carrying
  • Quite reliable for long-term usage

CONS:
  • Has a relatively weak throttle

I chose the Kohler 20RESCL standby generator for a number of reasons. One, it features a composite noise dampening enclosure, comes with a remote online controlling feature which means I can easily control it wherever I am through my SmartPhone, and three, it’s backed by a 5-year warranty. The generator still works great a few years after I bought it. I would say it a great value for money.

I bought this generator in 2016 and I just love how reliable it is. I was really getting frustrated with frequent power outages in my area. Sometimes the outage would go for more than 8 hours. Kohler has solved our problem. I especially love the fact that it’s automatic – no need to go outside to start it.

I absolutely love this generator. However, I don’t like the fact that its operation cost is too high. It runs on propane and a single gallon costs around $3. So if you experience a power outage for a whole day or for a few days, the costs can quickly add up. Overall, it’s a great generator.

Whole House Generator Buying Guide & How to Choose

There are many whole house generators in the market, but not all will suit your particular needs, and so you cannot just settle for the first one you come across. To ensure that you make a wise pick when shopping for one, you need to consider the following important things.

  • Power Output

The power output of the generator will determine whether it will be appropriate for your household or not. But, the ideal power output for you will depend on your consumption. To make sure that you choose a generator that is powerful enough, you should add up the watts of everything that uses electricity in the house and choose a model that can supply that wattage or more.

  • Fuel Type

With generators, the type of fuel used also matters as it will determine everything from how much it will cost to operate to its environment-friendliness. Typically, whole house generators will use propane, diesel or natural gas. The cost of fuel and availability should make it easier to pick between the three options. Generators that have alternative fuel capability will be an even better choice as they will not limit you to just one fuel source.

  • Ease of Installation

Installation is often the most challenging part of buying whole house generator because even if you have the best one it might still not serve you well if it is not installed correctly. While some models will allow for do-it-yourself installation, most will require a licensed electrician for installation. It is important to note that the more complicated the generator is the more cash the electrician is likely to charge you for installation.

  • Features

While different whole house generators will have different features, there are certain features you need to watch out for to ensure what you buy serves you well. These features include things like automatic start, fuel gauge, alternative fuel capability, low-oil auto shut-off, noise reduction, transfer switch and wheels for mobility.

FAQ

Can I install a whole house generator myself?

Yes. It is possible to install a generator on your own without the services of a technician as some manufacturers will include pre-wired systems and comprehensive step by step installation instructions. However, for your safety and to ensure you adhere to electrical codes of standards, you should not install it on your own unless you are a trained and licensed electrician.

How long does a whole house generator last?

It depends on the build quality. However, the average life expectancy of a typical whole house generator is 15 years when used for normal standby conditions. Also, the lifespan of the generator will depend on the frequency and quality of maintenance.

Is it more cost-effective to replace utility company electricity with a whole house generator?

No. It is not cheaper to use a generator instead of buying power from a utility company as fuel costs would be much higher. A generator works best as a standby source of electricity in case of emergencies and power outages.
