Do you live in an area that experiences a lot of bad weather, such as hurricanes? Or are you currently in the middle of different home improvement projects? With these situations and many more, the power in your home can be impacted. It’s for this reason that having a generator nearby is so highly recommended.
In addition to helping you live more comfortably, one of these can mean not wasting food in your fridge or being able to stay warm when it’s cold out. If you’re ready to invest, then take a look at the top 5 best generators for home use below; they won’t disappoint.
Best Generator For Home Buying Guide
Know Your Fuel Options
Does your home have natural gas? If so, you could install a backup generator that taps into the natural gas line if there is an emergency. This has the benefit of eliminating the need to keep the generator supplied with gas. On the other hand, it is only an option if you have a working gas connection. That means you can’t get a natural gas generator if there is no gas line or if you haven’t paid for a hookup.
Do you have a propane tank on the premises? This is often used to power propane heaters on rural properties. But you could use the same propane line to run your natural gas generator. This is more expensive than tapping into a natural gas line, but you don’t have to do as much refueling as you would if it as a gas-powered generator. Unfortunately, it is expensive to refuel a large propane tank. And it can be difficult to procure additional propane tanks in an emergency, though you could use large ones suitable for running a gas grill to run your propane generator for a while.
In most scenarios, the gas-powered generator is the best option. It is the ideal solution for most portable generators unless you’re relying on propane tanks for everything. For example, some RV owners who rely on propane for their stove and to power their refrigerator may want a propane-powered generator or a duel fuel version that can run on gas or propane.
Determine Your Power Requirements
A real home generator buying guide will give you the information you need to find the right generator for your home. And that starts by determining your power requirements. Is your goal to buy a generator that will run essentials like a heater when a winter ice storm knocks out power to your home? Or do you want to be able to run your home almost normally for weeks on end? This may be necessary if you live in hurricane-prone areas where it makes take a month to restore power to condo buildings on the shore or rural areas that are last to get serviced.
Generators are rated in watts. You’ll pay more for those that can put out more power, such as going from a 5,000 watt generator to a 10,000 watt generator. But you always need a generator with the ability to produce more power than you intend to consume.
Start by creating a list of appliances you plan on running during a power outage. A refrigerator runs anywhere from 500 to 1000 watts. A small space heater uses 750 watts, while large ones consume 1500 watts. Keeping a chest freezer cold will require 600 watts. A fan will require 50 to 150 watts depending on size, but your furnace fan system consumes 750 to 1200 watts. If you want to live a rather normal life while the power is out, factor in the power consumption of appliances like TVs and washing machines.
List everything you may have power drawing from the generator, and then total up the total watts they consume. You can use rough estimates for the product class, though it is better to check the control panel on the appliance to know for certain.
Then multiply the load by at least 10 percent go give yourself margin, since you may have small power drains such as items pulling power though they’re turned off or on standby. Give the generator another 15 percent margin, since the air conditioner, refrigerator or water pump will require a power surge to get started before dropping to the steady-state load.
Consider Any Extras That May Determine What You Need in a Generator
If the goal is to keep the essentials going during an emergency or be able to power your lifestyle while traveling in an RV, ensure that you can charge smartphones and other critical appliances. In this case, even a portable generator should have the ability to produce power with low total harmonic distortion. And the ability to plug in your smartphone or computer directly into it to recharge is worth the extra cost.
Not every home generator buying guide addresses issues with peak power loads. For example, you can save power by turning off an appliance, but you’ll eventually need to turn the refrigerator or freezer back on to keep things cold. Or you may try to keep cool by running fans but need to turn on the heat pump or air conditioner to cool off the interior of your home.
A 1500 watt air conditioner may pull 1800 watts during that restart. One solution is buying a generator with a much higher baseload to handle the extra load as multiple appliances turned on. The alternative is getting an inverter generator with a capacitor that can store power and provide that “surge” during the short-term peak load.
An inverter generator may be necessary if you’re running sensitive medical devices, too. For example, there are portable CPAP machines and oxygen generators that need reliable power. And you can’t run the risk of burning it out due to power surges from a generator that’s acting up.
Consider Operations and Maintenance
Any generator you choose must be easy to fuel or refuel. A unit may get points for being fuel-efficient, but every gas generator will need to be refueled once or twice a day if it is running continuously. Maintenance tasks like changing out the filter or replacing the spark plugs should be straightforward.
If the generator is going to be run regularly or for extended periods of time, then you want a low-maintenance generator. Don’t forget to check the availability of replacement parts, especially if the generator is used regularly or exists for emergency usage.
Do you have weak upper body strength or just hate pulling a pull cable to start a generator? Then one that starts at the push of a button may be to your liking. However, some units require batteries in the control panel to start it, while others only work properly if the inverter is kept charged through regular use.
Understand the pros and cons of the starter built into a generator before you buy it. Some owners choose units that start with either a button or a pull cable so that they don’t have to worry about being able to start it when the power is out.
Best generators For Home
WEN Model 56475, 3750 Watt Generator
This portable generator comes with a wheel kit that makes the generator as portable as possible. That makes it a better than average value. A kit that allows it to run at higher than a six thousand foot elevation costs extra. . It comes with carrying handles out of the box, though they must be attached to the frame.
The unit we recommend comes with a convenient electric start button. However, you need to verify that the generator you’re buying has the electric start button because there are versions of this generator with a pull-cable instead
This Wen generator is perfect for those who are concerned about their environmental impact. It meets the very strict EPA III and CARB (California state) standards. This means that it has the lowest level of particulate pollution and highest levels of fuel efficiency you can find barring a few, more expensive versions. That doesn’t mean you can use it indoors, but it won’t create as much smoke or the same nasty smell as conventional diesel generators.
This generator provides a steady output of 3750 watts. It can deliver 4750 watts of “surge” power, such as the load generated for a few seconds when you turn on a small refrigerator or air conditioner. This is a much higher surge capacity than comparable generators. The unit has a standard 30 amp plug, 120 volt RV receptacle and two 120 volt power plugs.
Wen does not use the highest quality parts. You may find that the fuel tank has started to rust after just a year. You have to flush the fuel tank and change the oil more often than average to keep it operational. The castings are so thin they can snap off. The frame itself could be damaged during shipping. The battery charger often goes out. Note that the battery is required to power the electric starter.
Check for broken parts when you receive it and contact Wen immediately, or they won’t assist you. The problem is that tech support and customer service may not help you if this does happen and you report it immediately. Wen will more readily ship replacement parts that can be mailed than service the whole generator.
- Environmental friendliness
- Relatively large surge capacity
- Poor quality parts
- Terrible customer service

It will fit in the generator cubby or storage compartment of every RV, though it should not be operated inside of the RV itself. The unit even comes with a carbon monoxide detector.
This generator comes with a built-in inverter. It has two 120 volt 20 amp power plugs. There is a single 120 volt 30 amp RV plug. It comes with two USB charging ports. This generator is ideal for those who need to charge smart devices, because it offers high power quality. This is the best generator for home use if you’re living out of your RV.
The Briggs and Stratton inverter generator is not as easy to use as some models. Turn on the fuel valve, hit the activate switch, and the start button will turn blue to show that it is ready to be turned on. The generator will blink green when you start the generator.
You must unscrew cover to adjust choke manually every single time you start it. If the unit doesn’t start out of the box, it is a hassle to get it serviced. Unlike generators that rely on a pull cord, it requires a working battery. That battery may be drawn down by the carbon monoxide detector or other electronics that show you the state of the generator during operations. Aside from the electrical issues, it works well.
While the generator comes with a funnel for adding oil, the location to add it is difficult to reach. The unit has small wheels built into it, but this generator shouldn’t be pulled to a campsite in the woods. The wheels and carry-handle are flimsy.
- Lightweight, compact design perfect for RVers
- Safe for charging smart devices and has the plugs for them
- Comes with a carbon monoxide detector
- Not easy to start
- It May not start at all

It is also designed to be connected in parallel with a similar generator, so you can get twice as much power out of it. It is very quiet, too. It is up to fifty percent quieter than comparable generators. And it is rather small.
It is 20 inches by 17 inches by 17 inches. That allows you to store it inside an RV luggage compartment or anywhere else, though it shouldn’t be run inside the RV. At 74 pounds, it has an average weight.
This generator has 3000 running watts and 3500 starting watts. Better yet, it is designed to be connected in parallel with a similar generator, though that requires hardware you don’t get with the standard generator purchase. Many RVers appreciate the excellent power quality and the two USB power outlets that let you safely charge smart devices. It is also a quarter lighter than similar generators.
The manufacturing quality isn’t ideal. It doesn’t always have sealed case seams. The handles aren’t as rugged as they could be. These units may stop working after a few months of steady use. It is also hard to start. It can be hard to start. And it can be hard to restart if it shuts down due to the overload protection kicking in because it revved up too high after the initial startup.
- Relatively quiet
- Designed to support RVers
- Hard to start
- Middling quality

Best generator for home – FAQ
Many people asked so many questions on best generator for home .We have answered all questions below .We hope you will be satisfied.
01. What is the best generator to buy for home use?
Standby generators are the best generator for home. By understanding the features, you can choose a reliable unit to suit your needs. Some of the top models are:
All Power America 9500W Generator
All Power is a dual-fuel unit that delivers 9500W on gas and 7250W on propane. It boasts of an 8-gallon tank that can take you for 10 hours at half load. Also, it offers two starting options – a recoil start and a push-button start. The noise level is rated at 76 decibels. All Power America generator comes with solid wheels and is EPA certified.
Briggs and Stratton Standby Generator
This is a 3700W electric start generator that comes with a pull-up handle and tires to ensure portability. And with its 3.5-gallon fuel capacity, this model can run for 16 hours at a quarter load.
Durostar DS 10,000W Generator
This is a 10,000W generator that offers continuous power thanks to the 8-gallon tank. The unit will run for 10 hours at half load. What’s more, the idle control will modify the revs when the power requirement is low. Since the backup generator is designed with two circuits, each can supply 3900W individually.
02. How big of a generator do I need to run a house?
To determine the type of generator you need, you should figure out the starting wattage of your appliances. Some of the items on top of the list include AC units, refrigerator, lighting circuits, and a freezer.
Also, the generator should be big to exceed the combined wattage. If the generator is too small, it can overheat or automatically turn off. Similarly, if it’s too large, you’ll pay for the cost to operate it.
The best generator for home can deliver up to 10,000W, and this is enough to handle critical appliances. If you have an air conditioning unit, a typical model requires 2200 starting watts and 1500 running watts. A general rule of thumb is to choose a generator that is big bigger than your power needs.
It’s better to have a unit that exceeds your power requirements than one that is too small. For critical household appliances, you need a generator rated at 5000-7000W.
03. What is the most reliable home generator?
Westinghouse WGen 9500DF
Westinghouse is a dual-wattage generator that produces 12500 peak watts. It features a 457cc 4-Stroke OHV engine and comes with a 6.6-gallon fuel tank that can run for up to 12 hours. And it can power major appliances like a refrigerator, air conditioner, lights, and sump pump.
This model features a remote start key knob for added ease at a distance. There’s even a display that shows critical data like lifetime hours and volt output. For portability, the generator comes with a handle and never-flat wheels.
The dual-fuel operation allows you to switch between gas and propane – and you can choose the best without shutting off the unit.
04. Is it illegal to use a generator to power your house?
No. Anyone can go to a hardware store and buy a generator to ensure they have a reliable power supply. If there’s no emergency and your generator is too loud, there could be a local ordinance against excessive noise.
05. Are whole house generators worth it?
Yes. A whole house generator can be a lifeline in case of a power outage. Generally, a power outage is predictable and can be destructive.
When the power goes out, the contents on your freezer and fridge go away. A standby generator can be a worthwhile investment if you live in an area that experiences blackouts. These units can help you live comfortably and minimize losses during periods of a power outage.
Some units support dual-fuel (can run on gas or propane). When the power goes out, they kick in automatically. And because you don’t have to do anything, you just sit and wait for the lights to come back.
In terms of cost, a whole house generator can cost $7,000 to $12,000. But the price will solely depend on the number of appliances you wish to power and the size of the property. It’s a matter of cost-benefit analysis. If you install a standby generator at home, you may want to sacrifice appliances that consume a lot of power, like AC units.
If you work from home, a whole house generator can be a worthwhile investment. This means you won’t suffer a financial loss in case of a power outage.
06. Will a 7500 watt generator run my house?
With a 7500W generator, you can power appliances like a water heater, freezer, sump pump, refrigerator, oven, and lights. It’s also a great choice to run a toaster, blender, coffee maker, and more. If you’re not sure whether this is the right unit for you, you should take stock of what you wish to power and those things you can’t live without.
But here is the catch. You must first determine the startup watts and running watts. If you have a central air conditioning system, you need 3000 to 6000 watts of continuous power. You can also run your laptop or watch television while still under 4000W.
So, is a 7500W generator the right size for you? This unit can be the best fit if you have a tool that requires high surge power. The best generator for home will keep the appliances running smoothly in case of a power outage.
07. How long can a Generac generator run non stop?
Generac is the perfect unit for any occasion. But one question that lingers in people’s minds is, how long can you run the unit continuously? While giving the number of hours is easy, many factors affect the running time.
For instance, Generac XD5000E will give a running time of 8 hours when on half load. But the narrative is different as powerful models can run up to 30 hours on 50% load. Since the fuel capacity differs, you expect units with a large fuel tank to last longer.
Standby Generac models can run continuously for 90 hours (more than three days). Those models with a 95-gallon tank can run for 100 hours.
The operating time will also depend on the type of fuel you use. The best models run on natural gas, gasoline, or propane. As such, you should stock your home with backup fuel to avoid unexpected shortages.
While the Generac generator can run continuously for days, you should use it as a backup power source. To ensure your generator operates for lengthy periods, make sure you replace the engine oil continuously.
08. How do you hook a generator to a house?
Determine generator plug type
What type of amperage are you working with? A generator with a big round plug will provide power on both sides of your breaker – the amperage will be written on both sides of the plug.
Determine the essential supplies in your home
A petrol-powered generator (3500W) is enough to cater to your lighting, fans, TV, freezer, and fridge. Then look at the requirement in terms of wattage. For instance, a microwave uses 1500W, while a refrigerator can use up to 1200W.
Choose a wiring system
You should liaise with the planning department to establish what is allowed in your country and what doesn’t work. The interlock kit is fairly easy and simple to install. However, this method requires safe installation, so you require the services of a professional. Not to mention, you must have a kit approved for a specific breaker box.
If you go for a manual switch, this can be the safest option, and there’s no risk of electrocuting yourself.
Install an inlet box hookup
The hookup goes outside the house instead of the holes you plug into. If you do the installation yourself, you should ensure there’s no faulty wiring.
Plugging it in (place the generator away from home)
Make sure the unit is far away from home – as far as you can. This prevents deadly carbon dioxide poisoning and prevents the house from catching fire. It’s a basic safety precaution that should never be ignored.
Plug the generator into the hookup
You ought to match the holes of the generator cord to ensure you have a complete connection. The next step is to place the attachment cable to the house. Once you plug it in, you can do the same to the receptacle. Make sure the throttle is in the correct position.
Switch the systems
Flip the main utility and turn on the generator. The other step is to flip the breakers and turn the loads. If you want to return the utility power, you ought to reverse the order of operations.
09. How do I choose a standby generator for my home?
This is a key feature to consider when buying a whole house generator. But first, you must work out your power needs and then decide the backup power that suits you best. Generally, a powerful standby generator can be somewhere between 20-50KW. If you have a 2500 square feet house, a generator with 22KW can be a good fit.
The best generator for home can either use natural gas or propane. If there’s no gas line in your area, you can install a propane tank.
Type of enclosure
A standby generator is made of sturdy material that can withstand harsh weather. If you want a material that can stand the test of time, you should choose steel or any other composite. You can also add an enclosure but be sure of the specifics first.
Most manufacturers provide a warranty of 4-5 years. Because standby generators are heavy units, you should work with a reliable dealer who offers maintenance and delivery services.
Automatic shut off
When it comes to standby generators, you should not underestimate the automatic shutoff feature. In case of a power outage, the generator will turn off automatically.
10. Is Briggs and Stratton generator better than Generac?
Generac and Briggs and Stratton are two brands of standby generators that offer the best performance. Before you make your investment decision, you should keep a few things in mind. Which one is better? In terms of price, Generac generators are more expensive than Briggs and Stratton counterparts.
Generac comes with a unique enclosure that features an aluminum material. Briggs and Stratton, on the other hand, have an enclosure made of galvanized steel.
Understandably, Briggs and Stratton come in a variety of sizes and are perfect units for visitors who live in condominiums. Besides that, most manufacturers recommend that you can install the units 18 inches away from the home. And, they are ideal for those with limited space.
Another reason why Briggs and Stratton are an excellent choice for many is that they come with excellent warranties. Some will provide cover for 5-10 years from the date of purchase.
Only invest in a model that will keep things running in case of a power outage.
11. Is there a tax credit for a whole house generator?
Whole house generators are partially tax-deductible when used as power equipment. But here is the thing – installing a generator does not make you qualify for a tax credit. If you use natural gas, local utility companies offer rebates, energy tax credits, and other incentives.
Installing a generator will increase your property value but also helps you qualify for capital gains tax credit.
12. How many watts do I need to power my house?
When estimating the number of watts you need in your home, there are a few considerations to keep in mind. The first thing you should consider is the startup watts – this is the extra wattage required to power your appliances. Then, you should check for continuous watts. If you want to power essential items, your home needs 5000-7000 watts.
Some of the appliances that require lots of starting power include an electric water heater, air conditioner, furnace fan, washing machine, washing machine, and refrigerator.
13. Will a 3500 watt generator run a house?
A 3500W generator is a powerful unit that offers more possibilities more than the 2000W counterparts. But first, you should how many watts your appliances need. Apart from powering your home appliances – there’s so much you can do with that.
Inverter generators are expensive than their conventional counterparts and you can give as high as 3500W options. If you buy two 3500W generators, you get 7000W.
Most homeowners run lights, a refrigerator, and a freezer. Such basic appliances can supply your home with 1000 watts – you can do a lot with the remaining watts. For example, you could power your microwave, charge your laptop, etc.
If you have a large AC unit, it should consume about 2000W of power. If you have a sump pump, it may require 2000 starting watts.
14. How much is a generator for a 2000 sq ft house?
If you have a 2000 sq. ft. house, you need a reliable backup power solution to take care of your needs in case of blackouts. The truth is, your requirements will depend on what you want to power. When choosing the best generator, pay attention to the basic usage (starting and running watts).
But the best generator to power your 2000 feet house doesn’t come cheap. These systems cost $2000-$15,000 depending on your power needs. You should pay attention to appliances like an electric water heater, refrigerator, central AC units, and lighting fixtures. For such basic appliances, you need an 11KW generator.
But again, the costs vary depending on the location. You can supply a 2000 square feet house with 7KW – 22KW generators. For such units, you should expect to pay $4000 – $10,000.
While this is just an estimation, you should factor in the installation costs and any scheduled maintenance.
15. Are whole house generators noisy?
One of the issues you have to deal with when running your generator is the noise level. Generators operate at specific RPM, so you should expect an audible spectrum at specific levels. And they produce at a variety of decibels range.
Whole house generators emit noise that can be heard 20 feet away. For instance, Generac iQ2000 produces 62 decibels while Westinghouse WH1000i operates at 59 decibels – quiet enough to hold a conversation.
Because there’s no such thing as a quiet generator, there are a few things you should keep in mind. How much power do you need? A generator that runs at 17KW produces less noise than a 35KW generator. If you need to power more appliances, you expect a noisy but more powerful unit.
When shopping for best generator for home, you must factor in the fuel you want. Generators that run on gasoline emit more noise than those that run on natural gas.
But there are other variables – is the generator running at half or full capacity? A generator will produce less noise when running at half capacity compared to units that operate at full capacity. You should choose the noise level you’re comfortable with.
If you’re looking for the quietest whole house generators, you can compare the various Generac models. Briggs and Stratton also offer the quietest units. The noise level boils down to the composition of the engine.
