Final words

When you are buying the best whole house generator, you need to make sure it meets your needs. You have to consider the weight of the item, power wattage, fuel tank capacity, and price.

However, if you need the best overall model, we will recommend WGen9500DF from Westinghouse. It is a powerful, dual fuel generator that is best for your needs.

Buying Guide

Buying the best whole house generator is a bit tricky job. The reason is that they come in two different types i.e. standby or portable generator. There are a lot of other factors too. However, let us start with this one.

Standby vs Portable

When it comes to large generators, many people prefer standby generators. Taking decisions becomes trickier if you don’t know how to maintain them. So, let us dive deep into this discussion.

Portable generators, as indicated by the name, they are very easy to move. If they are not connected to the circuit breaker panel, you can easily move them. Many people claim that they are less powerful and produce more power. However, we saw the last product from Generac. That was a portable as well as a powerful generator. They whole house generator cost less, are easy to maintain, but you need to start them every time power goes.

Now let us explore standby generators. As you see from the name, you don’t need to start them each time. They are on standby and will power on as soon as mainline power goes off. This makes them critical in areas where you need 24/7 power. They are stationary. So, you can’t move any of them. Usually, standby ones are more powerful and produce less noise. However, they are very expensive and need time to time maintenance.

With this said, now it is up to you to decide the best whole house generator as per your need.

Output wattage

You need the most powerful generator in your home if you have extreme power needs. In this case, I will recommend Generac 7043 or Generac 5734. Both of them are very powerful and will fit best for your need.

If you have a medium or small family, then investing in so much powerful generator is useless. In this case, I will suggest you purchase the best small quiet generator  one from Duro Max. They are the best ones and are efficient in working.

Fuel tank capacity

If you are using a standby generator, then you don’t need to worry about fuel tank capacity. However, for portable generators, you need one that comes with a large fuel tank. Since you need your generator to light the whole house, it must store enough petrol to keep the power on for long hours. We will suggest buying Generac 5734 GP15000E, as it comes with a large fuel tank of 16 gallons space.

Noise level

If you opted for a standby generator, you are free from worry in terms of noise. They work with less noise and will never become a problem. However, portable ones are noisy sometimes. Before buying them, make sure that it is quiet and make the noise less than 80 dBA.

Safe to use

The whole buying guide is useless for you if you opted for a standby generator. However, you need to read with care if you are ready to buy a portable one. You must make sure that your generator comes with all the safety features. It should have an idle control as well as low oil auto-shutoff. These options will save your investment in case of any mishap.

Easy to start

The best whole house generator must be easy to start. Some models come with a remote start feature while others start with a press of a button. They are safer than other models that need a kick to start.
