10,000-Watt Generator: The Guide To Go From A Beginner To An Expert

When a typhoon or a tropical storm causes a nationwide blackout for more than a week, you have no choice but to depend entirely on your generator for the electricity of your house.

A 10,000-watt generator is not cheap at all. Considering that many questions pop up in our minds while making this significant purchase.

Is a 10,000-watt generator enough to power an entire building? How long will it run? How safe is a 10kW generator?

Here is an extensive guide to learn about 10kW generators, from A to Z, so you can find out if this is the one power source for you.

The ABCs Of 10kW Generators

Areas around the country have experienced power outages for many days after natural catastrophes (hurricanes/ tornadoes/ snow storms/ flooding, etc.).

Having a backup power source on hand may save you money and aggravation when disaster strikes.

A generator with a power output of 10,000 watts will power heavy-duty appliances in your residence, a wide variety of equipment on a construction site, or a considerable number of RV accessories.

Everything About Wattage 

The wattage of a generator measures the difference between the amount of energy it generates and its consumption.

Excessive workloads need more power from a system than a less-demanding device. Smaller gadgets like lights, chargers, and coffee makers, on the other hand, require less electricity than their bigger counterparts.

You may estimate how much “room” you have for the beginning watts or surge watts before utilizing the 10,000 watts of your generator by calculating how many appliances you are operating simultaneously.

The more power (wattage) your generator produces, the more fuel it uses.

Before choosing a generator size, make sure you know what vital components you need to operate during a power loss.

If you’re running a 220-volt electric range or central air, you’ll need more power for starting up—sometimes 1,000 more than you’ll need for operating it. 

Types Of Watts

Now, a more excellent grasp of what generator wattage implies and calculating it. What happens next remains to be seen. There are two kinds of watts.

Let’s take them one at a time for clarity’s sake.

Surge Watts

Surge watts are the maximum wattage a generator can generate, used to start motor-driven items like a refrigerator or circular saw for a few seconds.

However, there are no surge watts in small appliances. A power booster (surge watts) is unnecessary since they do not consist of compressors or motors.

Surge watts are also known as starting watts or peak power. 

Surge power can damage your expensive electronics if they are left on for an extended period.

Therefore, professionals always recommend the use of surge protectors. If you want to know more about it, you can refer to our blog here.

Continuous Watts

Running watts are the amount of energy your appliances require to work for hours on end. Your generator must always provide this quantity of electricity to this equipment. It doesn’t matter whether you have a small or a large generator.

There is a considerable difference between surge and running wattage, and the former will always be the larger quantity.

It is sometimes known as continuous power or rated watts.

Let’s Calculate Generator Wattage

Learning how to calculate generator wattage is the most crucial step that every generator owner needs to know.

Still, we have seen that some consumers ignore it, and that’s why they overload their generators, which leads to damage in the future. 

Your device will be able to draw all the current and voltage it needs. Amperes (or amps) is the unit of measure for the current flow. Most appliances need just 240V and 120V, and this information is readily available on the surface of any item.

Moreover, you can refer to the retailer’s site or the instruction manual to specify the device’s features.

A simple plug-in and wattage calculation are all that are required. This formula, provided below, makes it simple to determine watts.

Watts = Amps x Volts

The problem is that some customers say they don’t read or understand amperes. The good news is that figuring out amperes is just as simple, and the equation presented below clarifies how to do so.

Amps = Watts / Volts

Different Variants Of A 10,000-Watt Generator

Various generators have been developed to meet people’s demands in multiple situations, including crises, places, and jobs. Some of these types use no electricity, while others have high portability.

To make an informed purchase, it’s essential to familiarize yourself with the many kinds and variations of generators.

To start working, generators need a variety of energy sources. It is typical to find four different models of 10kW generators on the market. Start with the basics and work your way up.

Solar Generator 

As we learn more about the dangers of global warming, environmentalists’ concerns are growing. There has been an increase in clients choosing solar power generators to help the greater good.

The system’s electrons generate direct current (DC) electricity. When the battery is being charged, the charger controller adjusts the voltage to make it safe.

Solar generators are becoming more popular since they emit no carbon monoxide emissions.

Solar generators are known to be the preferred choice of the younger generation.

Standby Generator

It is common to utilize a standby generator in an emergency, sometimes called a backup power generator, since it is automatic and can sustain your needs without impacting your lifestyle.

The home’s appliances and light fixtures are powered by the generator whenever there is a power outage. There are a variety of 10kW backup generators to choose from, depending on your budget and needs.

For example, they are the primary source of running water for rural populations, and electricity is needed to power the water pump.

Depending on the kind of fuel and the size of the generator, standby generators may supply electricity for days without lagging during extended power outages. The energy for a backup generator might be either diesel or gaseous propane

Modern generators can operate on two fuels, which is an option. Dual-fuel generators are the name given to these machines.

These power sources use a range of fuels at the same time to maximize output and cut down on maintenance expenses.

Inverter Generator

Inverter generators are an upgraded spin on mechanical energy sources. These generators are more compact while providing cleaner energy to ensure the safety of your electronics.

Here are some more benefits of inverter generators:

1. Performance 

The inverter generator’s fuel efficiency is one of its key advantages. As a result, it is lighter and easier to transport. Because these goods don’t generate as many fumes as traditional ones, they are better for the environment.

2. Portability

An inverter generator is easier to transport than a standard one, and these generators are smaller, lighter, and easier to carry. Whether a product is fair enough to be taken by its handle doesn’t matter if it has built-in wheels.

As a bonus, storing the device between uses will be more convenient. As we’ll see later in this article, the weight and utility of these goods are also affected by fuel.

3. Less Noise

Another key selling point of an inverter generator is its quiet operation. Tailgating or camping with a regular generator is out of the question due to the noise it makes.

On the flip side, inverter generators can be used even for events such as weddings and parties as they make zero to no sounds, thus improving the overall experience of the occasion.

4. Affordability 

Unlike a regular generator, an inverter can adjust its power output depending on how much load you place on them, hence saving you money on energy and fuel.

Conventional Generator 

A standard generator’s engine uses propane, gasoline, or diesel to convert mechanical energy into electrical energy. It’s relatively unusual for some versions to feature a propane backup fuel source.

A voltage regulator ensures a constant flow of electricity. This generator emits exhaust fumes, much like a car or a lawnmower.

It is a given that more energy is produced with a larger model. Conventional generators are the best choice for a flexible product with a high-power output.

Therefore, it’s an excellent choice for contractors who need a constant electricity supply while they’re working. 

However, there are a few shortcomings that you must be aware of because you purchase the generator. 

1. Noise Level

Conventional generators produce a lot of noise when the pedal hits the metal compared to the inverter generator. The extra power has a cost, which is an increase in the racket.

With the product’s specifications, you’ll discover this information. In general, they’ll be louder than 60 dB, and some of them may even reach 75 dB.

It’s roughly the size of a vacuum cleaner, in contrast. Keep in mind that noise levels over 85 dB are dangerous. For the sake of comparison, we recommend that you utilize this specification in your decision-making process.

2. Performance

The more recent technology of inverter generators also distinguishes between them and their traditional counterparts. 

Conventional generators have one major drawback: They can’t keep a constant RPM. Instead, it varies, known in the business as harmonic distortion.

Lack of clean power is one way to express it. It may not be a big deal for all power equipment, but it may severely impact computers and other sensitive electronics.

What Can A 10kW Generator Run?

Blackouts have risen throughout the globe over the decade. This means having a backup power source on hand may save you a lot of inconvenience during your disaster.

The consequences of a dimout will be easier to deal with if you have enough supply of fuel for your generator.

The majority of the time, you’ll be using 110-volt circuits to power your devices. Starting up an electric range or central air conditioner on a 220-volt circuit requires more energy than the operating watts.

Before deciding on generator size, make sure you know what vital components you need to operate during a power loss.

Try to determine how many starting wattages your generator can handle before purchasing it. Look at the nameplate on the appliance or contact the manufacturer to find out what watts it needs.

What You Need To Know About Fuel

1. Fuel Consumption Rate

Keep track of how much gasoline is used, at what power level, and how long. Think about how much and how long you can securely store gasoline.

Chemical additions to gas and diesel fuel may be necessary to remain safe for use after extended storage.

When it comes to generator fuel, propane and diesel are often regarded as the best options.

2. Shelf Life Of Fuels

You should know a few things about ordinary gasoline’s shelf life. It may take a year before diesel starts to deteriorate.

Because of oxidation and evaporation, Organic Ethanol may lose its combustibility in as little as one to three months.

Propane can last up to 30 years. Consult with your distributor for suggestions. You keep all fuels away from any possible heat sources in a cold, dry, and well-ventilated location.

How To Safely Run Your 10kW Generator?

1. Before Turning It On

Before refilling, turn the generator off and allow it to cool. The generator is going to be sweltering after a long day of use. Pouring flammable fuels may be dangerous while it’s still hot, so be careful.

Only use the kind of combustible that the manufacturer has prescribed.

2. Build Safe Bonds

The generator should not be connected to a wall outlet. Plugging a generator into a wall socket or the main electrical panel is never a good idea.

5. The Endless Risks

It is critical to connect your generator appropriately. When a generator is misplaced, there is a probability you might suffer from carbon monoxide poisoning.

Generators must be fitted with air-circulation safety precautions and reasonable exhaust controls in place. Improperly connecting a generator might result in electric shock or electrocution.

An overload might start a fire in the worst-case situation. Use a portable generator only when required to critical power equipment.

6. Double-Check Before Initiation

Before using your generator, turn off the main power supply to your house or company.

This is critical because the electricity from your generator might transfer back into the utility company lines, posing a threat to personnel.

7. Inspect Your Generator 

Maintain and inspect your generator regularly. Check the tank and valves for cracks and leaks regularly. Replace any damaged items right away.

You should follow the advice of your state and local emergency management authorities because each situation is unique. Always be cautious!

Where You Can And Will Go Wrong

Suppose we are purchasing a generator for the first time in our lives. So these aspects are critical for them to consider while making a purchase.

Cheap Built-Quality

If you want dependable service, you’ll require heavy-duty equipment with a long lifetime. Examine the product’s structure to confirm that it satisfies all of your requirements. It would be best to think about the expertise that went into its production.

Metal is a frequent material for high-quality generators, and it has a long lifetime. However, since the engine is subject to damage in harsh weather, it must be well safeguarded. Stainless steel or powder-coated cast iron plate may be used to achieve this.

If you are more worried about the safety of your generators during rainstorms, hurricanes, snowstorms, and so on, don’t worry since we have also explored it extensively. You may also look into it.

Low Running Time

Running time is one of the most significant factors to consider when selecting a 10,000-watt generator. However, this is not true for all 10,000-watt generators since fuel consumption has a substantial impact.

Depending on the load applied to your power source, a modern 10000-watt generator may run for up to 7-9 hours. This may decrease if you increase the electrical weight on your device.

Constant Uproars

We’ve all had the annoyance of hearing our generator produce a loud noise. Unfortunately, if there is a blackout, you may have to put up with these noises for an extended period.

Noise-cancellation technology is now being included in the machines of an increasing number of generator manufacturers. These devices considerably reduce background noise.

Keep in mind that the sound will not completely disappear, but once you’ve experienced it, the reduction will seem like a significant gift.

Can A 10,000-Watt Generator Run An RV?

A 10,000-watt generator is a wise investment if you own an RV since it can power your mobile home. Even though RVs are smaller than homes, you may have issues if you try to power too many different appliances at once.

Electrical Devices 

Not everyone who takes a weekend vacation in an RV wants to be completely alone. No matter whether you need to check your work email or keep up with your social media posts, a 10,000-watt generator will keep you online.


While everyone appreciates a campfire, it might be challenging to locate the campsite or clean up after dark if this is your only source of light.

Candles are terrific for creating a romantic mood but not so great for leading you late at night to the toilet. When you aren’t connected to the primary power source, you may power your lights and light bulbs with a 10,000-watt generator.

That’s it for now

A 10,000-watt generator provides enough electricity to operate all of your essential appliances in the event of a blackout. A 10kW generator is also portable and can be used for camping and other recreational purposes.

These generators may also run many camping gears. Moreover, you can charge your electronics even in a forest camp. A 10kW-watt generator can support all of these items, and it’s still up to you to figure out how to meet all of your power needs.
