What to Consider When Choosing a Home Generator

With each type of generator, there are several other factors and features that can affect its overall functionality when the power goes out. Keep the following considerations in mind when searching for the best home generator to keep you powered up in the event of an outage.

Types of Home Generators

Selecting the best home generator for power outages involves weighing the four different types available. Each type has its own set of pros and cons, and one is likely to suit your home’s specific needs better than the others.

Home Standby Generators

Home standby generators are large, permanently installed generators that connect to a home’s electrical panel for backup power during an electrical outage. They are equipped with an automatic transfer switch (explained in later sections) that automatically switches on the generator’s power supply when it detects a loss of utility power. Home standby generators are most commonly powered by natural gas or propane, but some diesel models are available.

Home standby generators have the largest power ratings and are usually, though not always, powerful enough to satisfy the electrical demands of an entire home. The downside is that they’re the most expensive to purchase and install, and they require installation by certified professionals. An electrician is needed to connect the home standby generator to the electrical panel, and a plumber may be required to connect the propane or natural gas line for the generator’s fuel source.

Portable Generators

As the name suggests, portable generators are small and able to be moved to different locations. They can have a wide range of power output ratings. Smaller units may only be capable of powering a limited number of electrical items and appliances, while larger units may be powerful enough to completely replace a home’s utility power supply.

To do so, the best portable generators for homes come equipped with a 30-amp outlet with which to connect a transfer switch. As a general rule, the smaller units are the most portable but the least powerful, and the larger units are the most powerful but the least portable.

Most options are gas-powered portable generators, but some are powered by diesel or propane. Multi-fuel generators (dual- and tri-fuel) are powered by multiple fuel sources, including gasoline or diesel, propane, and/or natural gas.

Aside from being more travel-friendly than standby generators, portable generators are usually more affordable. Keep in mind that portable generators should never be used indoors since the engine can emit a toxic level of carbon monoxide (CO) and lead to sickness and death.

Inverter Generators

Inverter generators are technically a type of portable generator, but they offer a different set of pros and cons. As opposed to conventional generator engines that constantly operate at the same output rate, inverter generators adapt to the power demand placed on them by throttling up and down.

This makes them more fuel efficient and also reduces their CO emissions. It also makes them much quieter than regular generators, usually only producing around a 60-decibel noise level: the same volume level of a typical conversation.

Inverter generators also boast greater fuel efficiency, allowing them to have smaller fuel tanks and more portability than other generators. All of these advantages make them a popular choice among campers and RVers who value silent operation and portability. The disadvantages? Inverter generators are typically more expensive than regular portable generators and generally produce less power.

Portable Power Stations

Portable power stations are essentially battery banks that store electrical power. Instead of using gasoline, diesel, propane, or natural gas, power stations are charged in a standard electrical outlet and/or via solar panels. Solar-powered power stations are often called solar generators and offer a practically unlimited and renewable power source—just as long as the sun is shining.

Portable power stations are usually compact and lightweight to make them incredibly portable. They are also virtually silent when in operation. In addition, they can also be safely used indoors since they don’t produce any harmful emissions.

The primary disadvantages are that they’re usually more expensive than conventional portable generators and have significantly lower power ratings that aren’t capable of providing power to an entire home. That being said, they can be used to power a handful of essential appliances during an outage.

Fuel or Energy Type 

  • Gasoline: A widely available fuel source, gasoline is a common source of fuel for portable generators. The primary disadvantages are that gasoline is more expensive and less efficient than other fuel sources, and gasoline engines typically emit the highest levels of CO. Also, storing gasoline for long periods of time requires a fuel stabilizer and can present a significant fire hazard if stored incorrectly.
  • Diesel: Although generators fueled by diesel aren’t as common as those fueled by gasoline, diesel is more affordable, more efficient, and can be stored for longer periods of time without a stabilizer. Diesel storage also doesn’t pose as significant of a fire hazard as gasoline.
  • Propane: Propane is an affordable and clean-burning source of fuel. It’s a common fuel source for standby generators and may either be tied into a home’s primary propane gas tank or have a designated tank strictly for the generator. It’s not commonly a primary fuel source for portable generators, but some dual- and tri-fuel generators will accommodate propane for a backup fuel source. The main disadvantages are that propane isn’t as energy efficient as other fuel sources, and a generator fueled by propane will usually have a lower run-time and produce less power. Propane also presents a fire hazard if stored incorrectly.
  • Natural gas: As a fuel source, natural gas is used exclusively with standby generators. For use with a generator, it is tied into a home’s natural gas line to offer a practically limitless source of fuel without worrying about running out of propane, gas, or diesel. The disadvantages are that natural gas is less energy efficient than propane and considerably less energy efficient than diesel and gasoline.
  • Solar energy: As a source of power for portable battery banks, solar energy is silent, clean, and affordable. In fact, it’s also free. The disadvantages are that the power capacity is determined by the number and size of the panels and the size of the battery it charges. A solar panel’s ability to charge a battery is also dictated by the amount of available sun, so it isn’t as reliable a fuel source as other options.


A generator’s size equates to the amount of power in watts it can generate, which can range from 800 to greater than 50,000 power capacity. Generators are sized in both “starting watts” and “running watts,” but the running watts rating reveals how many continuous watts the generator can supply to keep electricity running to the connected items. Starting watts refers to the number of watts the generator can produce for a few seconds to satisfy the extra demand from starting motor-driven items like refrigerators.

The running watts rating dictates the number of electrical appliances you can run simultaneously and for how long. Because a generator’s starting watts are usually 1,000 to 2,000 watts greater than its running watts, it’s important to distinguish between the two figures when determining your home’s power requirements.

Power Requirements

To determine the generator size you need, determine the total number of watts your most essential electrical items consume. All electrical appliances are required to have a label that displays their wattage rating; you simply need to add together the wattage figure listed on each item you want to power during an electrical outage.

Generally speaking, a refrigerator consumes between 700 and 1,200 watts, an air-conditioning unit consumes around 1,000 watts, a portable heater consumes about 1,500 watts, and lights can be anywhere between 60 and 600 watts. Most households will typically require around 5,000 watts to power its most essential components.

Transfer Switch

A transfer switch connects a generator to a home’s main electrical panel and allows you to switch, or “transfer,” between grid power and generator power. There are both manual and automatic transfer switches. Manual transfer switches require you to physically switch over the power at your electrical panel when the power goes out, while an automatic transfer switch automatically switches over power from the grid to generator power when it detects a loss of power.

Standby generators are all equipped with automatic transfer switches, and any generator with a 5,000+ watt power output requires the installation of either a manual or automatic transfer switch.

Although not always required, automatic transfer switches are recommended for portable generators of every power rating, as they prevent the possible risk of electrocution or fried appliances when manually connecting to the main electrical panel. It also prevents the need to run multiple extensions to various appliances in your home.


Generators can be equipped with various features that make their operation as convenient as possible. These include:

  • Electric start: Instead of using a pull-cord to manually start a generator, many modern generators offer an effortless electric start. This mechanism can be in the form of a push-button, a switch, and even an electric start operated by remote control. Automatic transfer switches also fall into this category.
  • Multiple outlets: Not only are multiple outlets convenient, but they also help distribute the generator’s electrical load when powering multiple appliances. Having a generator with at least four household electrical outlets is recommended for efficiently spreading the electrical load. Generators may also have household and/or RV 30-amp outlets, a 50-amp outlet, and USB outlets.
  • Low-oil shutoff: A generator with a low-oil shutoff will automatically turn off when the oil falls below a certain level. This feature can save a generator from irreparable engine damage caused by low oil levels.
  • Fuel gauge: A fuel gauge allows you to closely monitor the fuel level in the generator. This feature is typically only necessary for gasoline- and diesel-powered generators with internal fuel tanks. However, solar-powered battery banks usually have battery life indicators, and propane tanks often have integrated fuel gauges.


Along with the various features that contribute to convenience, there are also a few important safety features that many generators incorporate into their design. These include:

  • Automatic CO shutoff: To reduce the risk of CO poisoning when operating a portable generator, many are equipped with an internal CO sensor that will automatically shut off the generator when CO levels reach a certain level. This feature can be labeled as “CO Sense,” “CO Shield,” “CO Protect,” and similar designations.
  • Low-CO engine: Along with an automatic CO shutoff, some generator engines are specifically designed to emit considerably less CO. Despite being safer than conventional engines, low-CO engines still shouldn’t be operated indoors.

Tips for Using a Home Generator

Operating a generator isn’t complicated, but there are a few tips you should keep in mind to ensure effective and safe operation and avoid any harm to yourself or your generator when the power goes out.

First of all, it’s important to use extension cords that are sufficiently powerful. If you aren’t using a transfer switch, running undersized cords from your generator to your appliances can present a fire risk and also damage both the generator and connected appliances.

As a general rule, use at least 12-gauge electrical cords for larger appliances (like refrigerators) and at least 14-gauge cords for everything else. Cord length is also a concern since the voltage drop from cords that are too long can damage or destroy the appliances they’re supplying. Although you should keep a portable generator outside and away from your home, remember not to exceed a 100-foot extension cord length.

When running a home generator, it’s best to keep it on a level surface. If a generator is placed on a slope or hill, the internal lubrication system could malfunction and lead to premature engine wear and damage. Finally, ensure the generator has cooled down before you refill it, since spilling gasoline on a hot engine can cause a fire.

Keep the following tips in mind:

  • Prevent theft by securing your generator with a lock and chain if you store it outside.
  • Don’t run your generator with stale fuel to avoid start-up issues.
  • Keep extra oil and filters on hand to ensure you can maintain the recommended maintenance schedule through extended power outages.


Since generators can be both life-saving and expensive, it’s natural to have some questions before you’re confident in your decision. To this end, consider the answers to these frequently asked questions.

Q. What are the three types of generators?

The three types of generators are home standby generators, portable generators, and portable power stations. Some people consider inverter generators to be the fourth type, but they’re technically a subtype of portable generator.

Q. Do I need a permit for a home generator?

Most municipalities and towns require that you have a permit before a home generator is installed. However, not all locations have this requirement. Check your local guidelines to ensure that you have a permit if required for your city.

Q. What size generator do I need for my house?

To determine the necessary power rating for your generator, add up the wattage of all the appliances you want to run during an electrical outage. As a general rule, a generator should have at least a 5,000-watt capacity to power a home’s essential appliances.

Q. Do home generators need oil?

Home generators require oil to operate properly without wearing out the moving parts. You should change the oil in a home generator about once every 2 years or after 200 hours of use.

Q. Do generators have to be maintained? 

Just like your car, a generator’s engine requires periodic maintenance. This includes routine oil changes (after 20 hours of use for a brand-new generator and every 100 hours of use afterward), cleaning the air filter after 100 hours of operation, and ensuring that you run it for 20 or 30 minutes at least once every 3 months.

Q. Where should a whole house generator be located?

The exact placement in the yard depends on your personal preference, but most manufacturers recommend that the whole house generator is installed at least 5 feet from doors, windows, vents, and any flammable material. There may also be local regulations about the placement of a whole house generator, so make sure to check local guidelines to ensure that your whole house generator meets local building codes and installation guidelines.

Q. Can you plug a generator into a house outlet?

No. A generator should not be plugged into a house outlet because it is both dangerous and illegal in many locations. This is called backfeeding and it can severely damage the home’s electrical system or even cause a fire. Additionally, any technicians that are working on electrical lines on the same power grid are at increased risk of electrocution.

Q. How do you hook up a generator to your house?

You can connect a generator to your home appliances using a series of individual extension cords or if you want direct power for entire circuits in the home, have a professional electrician install a transfer switch.

Q. How long does it take to install a whole house generator?

On average, it will take an experienced technician about 1 full day to complete the installation of your whole house generator.

Q. How long do whole house generators last?

The exact lifespan depends on the specific product, but in general the overall lifespan of a whole house generator is about 1,500 to 3,000 hours.
