Factors To Consider Before Buying Best Home Emergency Generator

1. Wattage

The wattage of the generator is an indicator of the amount of power it has to operate whenever devices are plugged into it. Obviously, this is one of the most important things to know about the generator you are planning to invest in. Here is a simple way to know how much wattage you need in a generator.

Simply add up the number of watts of all appliances that you wish to connect to a generator in case of a power outage. This will give you a brief idea of the amount of load you need your generator to handle.

In addition, pay close attention to starting watts vs running watts. Many generators will require a higher amount of power to start up than while they are running. Thus, do not forget to add this starting value to the number of watts you calculated above.

Here are some rough numbers that help you sum up the basic necessities.

  • Refrigerator: 600 watts
  • Sump pump: 750 to 1,500 watts
  • Portable heater: 1,500 watts
  • Window air conditioner: 1,000 watts
  • Lights: 60 to 600 watts
  • Computers: 60 to 300 watts

2. Type Of Fuel

The three commonly used sources of fuels include natural gas, gasoline and propane. Of these three, most generators are powered by gasoline but have special cautions with regard to the exhaust fumes and carbon monoxide poisoning. It is thus important to operate such a generator outside of closed structures like houses or garages where there is plenty of ventilation.

On the contrary, natural gas and propane are the chosen alternatives for larger home standby generators. These fuels are much cleaner compared to gasoline. If you are concerned about the pollution a generator might create, you can always switch to a solar-powered model.

Although the capabilities and run times of solar-powered generators vary a great degree, they could be the right option for you if you have minimal needs.

3. Automatic Start

The automatic start feature of a generator allows it to get started immediately after the power goes out in your house/office, without the manual start-up process. This mightbe especially valuable if you frequently go on long trips away from your house. With a generator that starts on its own, you can be at peace as the vital systems like HVACs and sump pumps will still be up and functional.

On the other hand, some of them feature an electronic start option. This implies that the generator can be started by pushing a button instead of a recoil start type seen in small motor machines.

4. Transfer Switch

If you are planning on giving power to hardwired appliances in the event of a power outage, it is best to look for a machine that can be installed to work with a functional transfer switch. A professionally set up transfer switch will take care of safely disconnecting your house from the power grid and will supply power to the required circuits alone.

Which Type Of Generator Is Best For You?

Yes, we know there are too many models and variants available in the market to choose from. If you are confused about how to pick the right one for your needs, read this concise section to find out which kind of generator you might need.

1. Portable Generators

The most popular models of generators come in compact sizes and are usually mounted on wheels for enhanced mobility and positioning. From serving as an auxiliary source of power on sites to keeping appliances up and running during power outages, they are perfect for everything.

These generators require gasoline or propane as fuel. For this reason, they should always be left in open spaces and not inside enclosed buildings or garages. They are best suited for powering a minimal number of appliances. Therefore, check the wattage of the model you wish to buy beforehand and compare it to the required demands of energy.

2. Inverter

This is one of the most sought after alternatives to noisy and stationary home generators. It is powered by gasoline but has quickly gained popularity owing to its high efficiency and cleaner emission. It is commonly used in recreational activities like tailgating and camping.

An inverter generator could be the best home emergency generator for your needs if you are looking for something that is compact yet fuel-efficient. It is great for occasional recreational activities. You could also choose a more robust model if you are planning to operate it at home.

While robust models have greater height and weight dimensions, the efficiency of fuel consumption and the significantly reduced noise factor make this device a worthwhile investment.

3. Home Standby

Are you on the hunt for the best home emergency generator that comes with a huge capacity and can supply power for longer periods? Thanks to a readily available supply of fuel and high wattages, these home standby generators can supply for several days together if their fuel needs are taken care of from time to time.

These units are usually installed outside the houses and are connected to a fuel tank that is filled with propane or natural gas. The capacity of these tanks ranges anywhere between 500 gallons to 1,000 gallons in size and can easily last you a week’s duration or more.

These home standby generators usually have higher wattage and can power a variety of appliances at your home like HVACs, kitchen equipment, televisions, sump pumps, etc. The majority of the residential standby models of generators offer a wattage between 10,000 and 20,000 units of power. Some also offer up to 48,000 watts for greater durations of uninterrupted power.

Maintenance And Warranties

Even if the power does not go out frequently at your place, it is important to fire the generator up once in a while and let it run for some time. This ensures that the generator is in tip-top shape. Most manufactures provide you with information pertaining to basic maintenance.

However, the following pointers need to be followed to be sure of a safely functioning generator.

  • Let the generator run for at least 30 minutes per month. This will ensure that the motor and other components inside do not seize up and become prone to breakage. It is crucial to do these short maintenance runs in a fully-ventilated and open area.
  • Buy a fuel stabilizer and add it to the tank when you store a gasoline-powered generator for long periods of time. This additive will ward off any rust, sediment, or corrosion. Did you know that gas gone bad is one of the top causes of small engine failures? Thus, we advise you to not take proper fuel storage lightly.
  • Regular repairs and replacement of motor components (if necessary) should be done to minimize the failure of the generator. Look out for those constituents of the generator that are prone to damage/wear and tear like fuel and air filters, spark plugs, etc.
  • Do not let your generator run on low oil. By doing so, you are inviting major motor/engine damage. Keep an eye on oil levels and replenish them whenever necessary.


Most generators today are backed by a manufacturer’s warranty. Most residential portable and inverter generators come with about 2 to 3 years of warranty periods from the brand, which takes care of parts and labor charges. On the other hand, standby generators, which are usually a bigger investment, come with 3 to 5 years of warranty periods.

The terms and conditions of these warranties vary from manufacturer to manufacturer. Some of them take care of the cost of travel for a technician to visit your residence and service the generator. On the other hand, some do not cover these costs and will require the customer to pay.

Thus, it is advisable to pay attention to the fine print and know what will be covered in this regard beforehand.

Best Home Emergency Generators – Summing Up

During power outages, it is essential to have a generator that will keep you, your family, and your house warm in winters and cool in summers. Although the investment is considerable, we can assure you that it is worth every penny you spend. You no longer have to adjust to cold food or worry about your phones and laptops running out of charge.

Most people decide to invest in home emergency generators in case unforseen events like major storms were to occur. This makes them take desperate decisions without having the time to plan and analyze the real utility of such a generator. They might skip the basic and crucial safety steps during setup and many people die every year from carbon monoxide related poisoning.

Therefore, we advise you to consider our brief guide to help you buy the best home generator, calculate how much wattage you need, carefully examine the features of the generator, and cautiously get the unit up and running at your home!
