Best Whole House Generator – A Definitive Buying Guide

Buying a generator with enough juice to power an entire house is no easy task. You need to consider several different factors if you are to end up with the best product. Most people who buy it without enough information about the subject, end up with a unit that is not capable of providing sufficient power to the house.

To ensure you end up with the right device, in the following section of the article, we will take a look at some of the things you should consider when buying the best standby generator for home use.

1. Power

This factor really comes as a no-brainer when you are looking to buy a whole house generator. To check if the device you are getting has enough power, you need to add up the total wattage consumption of the electronics in your house and cross-check it with that of the generator.

2. Size

The size of a whole house generator is measured in kilowatts. It dictates the total load capacity of a specific device, which is a vital aspect of what makes the right product. Ideally, you would want a unit that has a minimum size of 20 kilowatts. Any less, and you might end up with something that is less than perfect for your needs.

3. Fuel Type

A generator typically uses three types of fuels, propane, diesel or natural gas. You should make your decision based on which fuel source is more available to you. Some generators even have alternate power options that allow you to use more than one fuel type. It might be a viable route if you want some flexibility in your selection of fuel.

4. Ease of Installation

Although, in most cases, you would not be setting up the device yourself, it might be worth checking if it is easy to install. If you are a DIY-person and want to take the hassle yourself, this factor is even more critical. You should get an instruction manual with any generator you buy to provide the information required for installation.

5. Durability

With any new device you purchase, durability is always a concern. You want to make sure there is no compromise with the build quality of the unit. Furthermore, take a look at whether you will have the manufacturers’ support if any problem occurs with your device.

6. Noise

With any powerful generators, noise is a major issue. If you do not want to deal with the loud buzz and hum created when producing electricity, you should look for a unit that features some sort of noise cancellation technology. It might seem like a small thing, but you would be amazed and frustrated with how loud the noise gets in no time.

7. Additional Features

You should actively look for any additional utility that may come with a generator when choosing one. Something as small as transport wheels make it easier for you to move it around and set it up wherever you wish. Other features to check when buying a generator are, auto shut-off, alternate fuel capability, automatic start, etc.

How to Set Up A Whole House Generator

In the next section of the article, we will give you a step by step guideline on how to set up a generator for your entire house.

  • The first step is to identify the appliances you want to power with the generator. Calculate the amount you would need, and cross-check with the ability of the machine you have in your hand.
  • Next, you want to install a wiring system. There are a few different options you can choose; we will go with an interlock kit. These are easy to install and comes with all the instructions required for set up. However, in some areas, interlock kits are not legal. So, make sure you check up on the laws regarding its use for your specific region.
  • You need to install an inlet box on an outside wall of your house. This box will allow you to hook up the generator to the rest of the house. It is best to leave this job to the professional; otherwise, your insurance might not cover any damages caused because of it.
  • Position the generator according to the recommendation of the manufacturers. Additionally, you would want the generator to have some sort of shade above it and a base to keep it above ground, to protect it against rainfall or snow.
  • Connect the generators’ cord to the inlet box and make any other necessary connections to the generator.
  • Double-check the engine, and fuel levels. Depending on the unit, the engine might require preheating.
  • Turn on the generator
  • You can test out the connection by turning off the power at the mains. If everything goes well, your house should now be powered through the generator in case of power failures.

A generator is not something to be taken lightly. You can easily hurt yourself if you are not careful and do not know what you are doing.

If you are not confident about your ability, it would be wise to hire a certified professional to set up the device for you. Although it might cost you some money, it would ensure that your health and life are not put at risk.

Safety Tips When Using A Generator

Now that you know how to set up your generator, you must be itching to set it up in your home. However, before you leave us, there are some words of caution that we should give you. Safety is a prime concern whenever you are operating a device capable of delivering high powered currents.

The tips mentioned below will help you prevent any accidents that may happen due to wrongly handling the generator.

  • Generators emit carbon monoxide fumes, which can be deadly when inhaled. So, you should never operate it in closed space. Always keep the generator in a well-ventilated environment, preferably outside.
  • When connecting appliances to the generator, make sure you are using heavy-duty cords instead of flimsy ones.
  • Before plugging the appliances, make sure to turn on the generator first. Turn your devices one after the other slowly in case of power outages. Turning on all of them at once runs the risk of overloading your unit.
  • Do not keep the generator in a wet condition. In the rainy season, make sure you place the device in a place where rainwater cannot gather up. Additionally, make sure your hands are dry before operating it. Remember, electricity and water do not make a good combination.
  • When putting in fresh fuel, make sure the generator is turned off and cool.
  • Do not let children come near the device, especially when it is running.
  • Do not touch the generator when it is active.

Frequently Asked Questions (FAQs)

How powerful of a generator should I get if I want to power an entire house?

Ideally, you would want a unit that has a minimum of 6000 watts of power. However, this value changes if you want to run multiple demanding appliances such as air conditioners. A minimum of 8000 watts of power should suffice for any average homeowner.

Should I hire an electrician or install the generator myself?

What is a standby generator?

A standby generator is a device that is always on but stays idle until it detects a power outage.
