You don’t want your generator to break on you

If you are in an RV, then it is probably not going to be that much of an issue if your generator fails on you. Click here to know the size of the generator that you need.

You may need to ‘slum’ it a little on the road for a while, but you can still do whatever it is you wanted to do.

If you are in a house, then your power going down can be catastrophic. You will lose your food. You will lose your phones.

You will lose your computers. All of this while you are waiting to replace your generator, or fix your current one. When you are buying a generator, you want to get something that is ‘built to last’.

Is the generator easy to repair?

It is sometimes worth spending a little bit of extra money to pick up a quality generator from a company.

However, even if you pick up a decent generator, there is no guarantee that it will be easy to repair.

Reviews will often point out whether it is quick and easy to get your hands on spares. They will also report on whether the generator is prone to failing.

If there are a lot of negative reviews, you may want to steer clear.

Is it the right generator for you?

Finally; these reviews will help you to determine whether it is the right generator for you. They may talk about the conditions that the generator works in.

They may tell you how far you can push that quoted wattage. They will tell you about the sound.

Basically, they will tell you everything that you need to know in order to make an informed decision about your purchase.

Whole house generators have a larger range in capacity, going from 22 KW to 48 KW.

This added power lets you not have to worry about making major decisions about what you want to run during an outage. 

The Best Whole House Generator Reviews will be your guide on this type of generator.

Instead, your home will nearly be fully functional, as if the outage had never happened.

Whole house generators have additional benefits too.

Their powerful engines are liquid-cooled to provide better run times without necessary maintenance, great programming for load management, and better fuel options such as natural gas, diesel, and liquid propane.

Standard home standbys can power smaller homes that have a kilowatt (kW) range of 9 KW to 20 KW.

Their smaller, air-cooled engines will provide short term-power to more critical items in your home like an air conditioner, refrigerator, sump pump as well as some of your lighting.

However, they aren’t made to power everything at the same time or backing up larger homes, or even running for longer periods of time.

Do We Really Need a Generator in Our House?

The Best Whole House Generator Reviews gris

There are many reasons to make a serious investment in a generator.

During severe weather, an overloaded electric grid, or natural disasters, you need to ensure that your food doesn’t spoil, that your medical equipment keeps going and that any mechanical systems you use to protect your home keep working in order to prevent any dangerous situations during these crucial times.

A generator can be essential in guaranteeing your safety during these periods.

This is why you need to look into the best whole house generators. Here are some handy tips on sorting it all out.

Tips for Choosing a Generator for the House

There are some major differences between whole house generators and home standby units.

These include: A whole house generator has a more high-quality engine–more automotive than a lawnmower (like you would find on a standby)

  1. On larger models, it is liquid-cooled rather than air-cooled to better handle extended outage times.

2. Lower RPMs make less noise.

3. There are longer maintenance intervals

4. A/C shedding options and load maintenance

They back up the entire home instead of only the most essential circuits

1. Fuel efficient

The Best Whole House Generator Reviews generac

The first major thing you will need to do when selecting a generator is to choose a fuel source.

This is important because in more remote or coastal areas, finding a fuel source that is abundant can be difficult.

However, many whole house generators are more accessible because they have a diesel option.

Tanks that require diesel or liquid propane will need to large enough to run properly.

If they run on natural gas, you will need to ensure that the meter and gas lines are the correct sizes.

Before you install your unit your contractor will verify this with you.

All information can be found on the installation manuals of the product pages.

2. Size

The next thing you will need to do is pick the correct size generator for your home.

This is crucial but often overlooked in the panic to get one installed before an oncoming storm. You will need to analyze the electrical load.

Check the manufacturer’s data plate on each piece of equipment or major appliance you will be using in order to determine the starting amperage.

The biggest wattage draws will be from your (central) air conditioning units.

To check on their size in “tons,” you will need to divide the number of the appliances BTUs by 12,000.

This would make a 5-ton unit equal to 60,000 BTUs. This next formula will help you figure out the total starting wattage for all of your appliances.

Starting amps x Volts=Watts

When you choose your generator’s output, select the rating that will be about 20 to 25% higher than the expected peak load.

(If you expect the wattage to be around 22 KW, choose 27 KW).

A more highly rated generator will work well at approximately 80% of full capacity, and this will provide some flexibility if you get more appliances and your load increases later.

3. Transfer Switch

final important thing you will need to choose is a transfer switch.

An Automatic Transfer Switch allows generators to turn on immediately once it has detected the power failing.

It can do this because it can sense the utility power, and once it has detected an outage it will start the engine while disconnecting electricity coming in from the power line.

Getting the right switch can be as important as selecting the right generator because they work together in order to restore lost power.

In order to pick which one will work for your home, you’ll need to know the amperage that is on your electrical service panel.

Check it by finding the main breaker in the electrical panel.

Usually, the average home will have a 200-amp main breaker, so that means that the absolute maximum amount of power the home can use is 200 amps. This means you will need the 200 amp switch.

Best Places to Buy a House Generator Online

The best places to buy a house generator online would be Lowe’s, Home Depot and Amazon.

If you buy from Amazon, you can save by buying the generator and the transfer switch at the same time.

Be sure to do your research, and make sure you know all the specs you’ll need before you make a purchase. Check out best generator deals on Amazon
