7500-watts generator has got your back! 

Purchasing a generator as big as 7.5kW has its perks. However, some shortcomings often escape your perspective.

In this blog, we will take an in-depth look and cover all the aspects of a 7500-watt generator to give a good idea about the capabilities and strengths.

So, let us begin!

Let’s Talk About A 7500-watt Generator

You are either buying a generator for the first time or already own a generator and are planning to upgrade it. However, knowing the basics is always necessary before making a final decision.

Cost – Invest Now, Save Later 

A 7500-watt generator does not come at an affordable price. Unfortunately, generators that arrive in this bracket lack a lot of premium perks, such as noise cancellation and a bigger fuel tank, etc. 

However, these generators do not fail to supply you with efficient energy production while lasting for a long time.

A 7.5kW generator ensures your lifestyle is not interrupted during calamities and runs your appliances smoothly to keep your peace and comfortable even during tough times.

So, when buying a 7500-watt generator for the long run, consider it an investment for your tomorrow. Moreover, by just paying a few dollars, you get a lot of upgrades that will enhance your experience to the next level. 

A 7.5k Watt generator is not too common and is often manufactured by big brands such as Honda, Paradox, and Duramax, and each brand has its own price. Thus, you have a wide variety of options to choose from.

However, the cost is not the only factor you consider when buying a generator. There are other checklists you need to confirm before taking any action.

Fuel – How It Affects Your Generator? 

Generators run on different types of energy. Natural Gas, Gasoline, and Diesel are among the most common kinds of power. You must choose what fuel suits you the best according to your location and budget.

A 7500-watt generator also comes with a dual or tri-fuel tank. This feature is currently limited to high-end generators and has the potential to become mainstream in the coming years. These multi-fuel tanks allow generators to run on more than one fuel type for efficiency and higher maintenance

Running Time – Not So Simple

It’s tough to put a specific value on a generator’s running time as there is no formula. This is because several factors are impacting the operation time of the device. Some of the more popular ones are mentioned below:

  1. Fuel Type
  2. Fuel Tank
  3. Generator’s Load

Ideally, most manufacturers calculate the running time of generators at a constant 50% of the load, and when it comes to a 7500-watt generator, it can give you an average of 14-15 hours of running time. 

The generator’s load is considered the most significant influence on its operation time, and the two are inversely related. This means if you increase the appliances powered by the generator at one time, you reduce the duration for which the generator will function.

Simply put, the heavier the load, the lower the run time.

Running time varies according to the fuel type as some combustibles are more efficient than others. This difference in productivity causes the generator to work for either a more extended period or a shorter one.

As for the fuel tank, there is not much to discuss. You just need to remember that the bigger the fuel tank, the longer your generator will run.

Durability –  A Must-Have In Premium Generators

There is no doubt 7500-watt generators are expensive. In fact, getting one will likely need some serious financial sacrifice on your part. Hence, if you want dependable service, you’ll need to get your hands on a piece of heavy-duty equipment with a long lifetime

Ensure you’re receiving a product that can manage all of your requirements by inspecting its construction. Look up upon its built quality. 

In general, good generators have a fairly durable construction. Your generator might be exposed to extreme weather conditions that can damage its engine. Thus, it has to be robust and well-protected. With stainless steel or powder-coated cast iron plate, this may be guaranteed.

You can also protect your generator from storms and disasters by using various shields and enclosures.

What Is Wattage? 

Wattage is the energy that our home appliances and electrical gadgets require for work. The wattage for every piece of electrical equipment is different.

This is mainly dependent on the size or function of the appliance. For example, some machines require more wattages than others, such as a home refrigerator and window AC, as they are heavier appliances than an LCD or a ceiling fan. 

Unfortunately, sometimes manufacturers don’t mention wattages on their devices. Instead, they utilize other measuring units such as Amperes and Voltage on their appliances.

An ampere measures the current flow in any device and varies individually, whereas voltage is a constant value of either 120V or 240V. 

If you don’t see any wattage on your device manual, you can still calculate device watts using the formula mentioned below.  

Watts = Amperes x Voltage 

All the important information regarding the appliance’s energy usage is placed on a label of the device or inside a manual. You can also refer to the retailer’s site to learn about its specifications.

Different Types Of Wattage

How often do you read a user manual of any appliance to identify its watts and see two separate values of wattage mentioned? 

This is because there are different types of watts, and a generator owner needs to understand each of them because a slight miscalculation of these watts will damage your home appliances. 

Starting Watts 

Starting watts are also known as surge watts or start-up watts. It is the power that your device requires when they begin working

You will see some home appliances that do not have starting watts as you investigate further. This is because only devices with motors require start-up energy to gain a push to begin their operation.

For example, the clothes dryer has 6750 surge watts, but a standard bulb has 0 surge watts. This is because a dryer requires more power to start its compressor while a bulb does not. 

Running Watts 

Running watts is the amount of power your appliances require continuously to keep functioning. This remains constant for hours and hours until you externally disturb them by cutting the power supply or shifting it from a generator to the main power supply. 

Remember, running watts are always lower than starting watts. 

There are also known as continuous watts or rated power. These watts do not fluctuate and remain constant. Hence, they can be easily calculated

A 7.5kW generator – What Does It Mean For Your Appliances?

A 7500-watt generator is a complete power pack, and you can run various appliances on it if it does not exceed its maximum output limit.

Heavy equipment such as a table saw or heavy devices such as AC can also be used on a 7500-watt generator. The recommended limit of a 7500-watt generator is 90% of the total power or 6750-watts.

Remember never to cross this limit, as it can be hazardous for your appliances and your safety!

When calculating the total power, do not forget to calculate the surge watts, as consumers often fail to evaluate the peak wattage required and buy a smaller generator. This results in unpredicted surges and can damage your electronics.

We have designed a table with a group of standard home devices to help you understand how a 7500-watt generator can aid you in your daily life:

What Can You Run On A 7500-watt Generator? 

Every generator owner must identify the appliances they want to run on their 7.5kW generator because planning is always better than being on the verge. Hence, we included some easy and quick steps to help you in your calculations.

Priorities – A Quick Checklist 

First, make a quick list of all the home machines you will be willing to use whenever the power goes out. This list is necessary because your generator can only supply a limited number of starting and running watts. 

We highly recommend you skip your entertainment devices because you will use essential electronics such as light bulbs, AC, refrigerators, and ceiling fans first in case of blackouts. 

Wattages – Starting & Running Watts 

The next step is to note down each value of the appliance you are willing to use from the above table, or you can also use the user manual if you can’t find the starting or running watts of your device from the table. 

Ensure that all the values that you are noting are correct. Minor errors in calculations can result in irreparable damages and severe inconveniences for you.

Calculation – Double Check It 

After making a list, note down the starting and running watt of each appliance you want to use in case of outages. Next, add every gadget’s rated power to calculate the required continuous energy.

Calculating the peak wattage of your generator is a little different, and you will first need to identify the highest starting wattage of all your appliances. Then, add this value to the total running wattage to determine the start-up power required.

Ensure that the values you got after your calculations do not exceed the maximum recommended limit of 6750-watts. 

Not Just A Household Generator 

You can use a 7500-watts generator to power your residences in case of blackouts. However, there are also some other uses of a 7.5kW generator, and these uses require the generator for special equipment and function differently from household machines.  

Industrial Use – Can It Sustain Heavy Duty Work?

Many companies and owners of workstations prefer to carry a portable 7.5kW generator if the power goes out on the worksite. Some jobs cannot afford a break; even in an outage, they need to run essential mechanical equipment. 

Industrial pieces of equipment require much more energy for both running and surge watts. So workstations always prefer a 7500-watt generator or a 9000-watt generator to fulfill their needs. 

For example, when a portable air compressor is in operation, it uses just 1600 Watts on average; but it takes 4500 Watts to start up, making it impossible to operate the air compressor with a generator producing less than 7500 watts output power. 

This is why 7500-watt generators are standard in working fields. They can provide energy to the most power-hungry equipment while still having enough left over to sustain several other instruments simultaneously, making them versatile.

For your better understanding, we have designed a table containing surge watts and running watts of standard industrial types of equipment so you won’t face any difficulty in case of a power shortage.

What You Need In A 7500-watt Generator

There are factors to consider if you plan on buying a generator this big. These elements improve your experience while ensuring a secure and safe time throughout a power outage. 

Types of Generator 

Like other generators, a 7.5kW generator also comes in different types. When choosing a 7500-generator, you should consider them all and compare them according to your needs to see which works best. 

1. Standby Generator 

A standby generator is a fallback power system that runs on its own. An automated transfer switch detects a power failure within seconds, alerts the generator to start working, and transfers the electrical load to the generator. 

The backup generator kicks on and starts producing electricity to the circuits. Automated transfer switches also restore utility power and tell the backup generator to shut down when the blackout is over. 

When the outage is over, it goes into standby mode. A backup generator runs weekly self-tests to respond quickly to a power interruption. 

2. Inverter Generator 

Inverter generators provide electricity in three stages: high-frequency alternating current (AC), direct current (DC), and stable alternating current (AC). This contrasts with standard conventional generators, which exclusively create alternating current (AC). 

Conventional portable generators provide more power than inverter generators. On the other hand, inverter technology produces cleaner power delivery that adjusts up and down based on load, with little harmonic distortion. 

Harmonic distortions are regular fluctuations in voltage and current caused by changes in frequency within electrical distribution networks.

Inverter generators are thus ideal for sensitive items such as mobile phones, LED TVs, audio equipment, and laptop computers since they avoid overheating and overload. Furthermore, t’s very rare for inverter generators to produce surges. 

3. Solar Generator 

If you have solar panels installed on your roof, you may utilize a solar generator to provide your home with electricity when the grid goes down.

However, since there isn’t just one sort of generator, it might be perplexing. They differ in kind, style, brand, size, and function. Solar generators provide a large selection that provides a wide variety of coverage to meet your demands. 

These days, solar generators are among consumers’ favorite types of generators.

Eradicating The Noises – Difficult But Not Impossible

Imagine listening to loud noise for hours whenever the power goes out. First, you are filled with concern regarding the blackout, and now you have sirens ringing in your background, irritating every cell in your body.

Sounds very frustrating, right? 

Modern generators have a pre-installed silencer in them, and this will help you reduce the noises from the engine whenever you go camping or use them inside your home. 

These silencers are also known as Mufflers and can be added to your generator as an additional accessory.

Warranty – Secure Your Investment

Generators do not come at a low price, and that is why whenever you choose a generator, make sure that it has a minimum of 5 years warranty time so that your investment can be secure before you can afford to buy a new one.

Portability – Make Camping Fun, Not Heavy

If you want a flexible 7500-watt generator for your recreational requirements, which may need you to carry it from one location to another, portability is essential. 

Check to see whether it was well-made so that it can withstand all of the movement you want to do. Moreover, choose one that is easy to transport.

Consider purchasing a portable generator with a handle and all-terrain wheels. Also, get something with a solid metallic frame or a lifting hook if you want something that can be readily lifted.

Safety Measures You Should Not Forget

Buying a generator is not enough. A 7500-watt generator is a heavy usage machine, and that’s why before using it, it is always recommended to take the following safety measures so that you can rest assured about the protection of your sensitive home appliances. 

1. Surge Protector – A Necessary Precaution

Your devices are at risk when they are connected to a generator. This is because a generator produces electric spikes or surge waves that can overload and damage your sensitive home appliances. 

The most suitable solution to these unpredicted electrical rises is a surge protector.  

A surge protector is a device that contains MOVs that absorb these electric spikes and then transfer them through the ground wire. Your sensitive electronic appliances would not suffer from high voltage and work fine with a generator. 

Good surge protectors come with an indicator that tells you the life about it. Don’t forget to change your surge protector every passing year. 

Here is a detailed manual about how surge protectors shield your houses from the dangers of unprecedented spikes.

2. Back Feeding – Illegal And Dangerous 

Back feeding a generator may result in death or injury to you or a utility worker and the destruction of your property. It is the practice of directly connecting a portable generator to your home’s electrical system rather than utilizing a transfer switch.

It’s hazardous, and it is often illegal. But unfortunately, many customers still believe it is acceptable. Under any circumstances, you should never try it!

3. Carbon Monoxide Detectors – The Final Warning

Carbon Monoxide is a poisonous gas emitted by your generator during combustion, and this gas can quickly accumulate in confined areas and suffocate within minutes. These are some safety measures that you should take to prevent CO from endangering your lives. 

  • Never use a generator inside your home. Collection of the odorless and colorless gas often goes undetected, which means you do not suspect any dangers until it’s too late.
  • Use the generator far away from any enclosed area because the gas can enter your house or offices through ventilation systems and open windows. It is best to have a distance of at least five feet between a generator and your residence.
  • Opening doors or using fans will not help you get rid of this gas. You cannot run your generator in a room even if you think the ventilation system is good enough. There will always be accumulation that can cause your chronic breathing problems.
  • A CO detector is a must-have device for every household that owns a generator. A carbon monoxide detector, often known as a CO detector, detects the presence of carbon monoxide (CO) gas to avoid carbon monoxide poisoning.

Key Takeaway Points

A 7500-watt generator is ideal for outdoor activities and heavy residence usage.

You will not have to worry about the power output once you plug your backup supply into the primary power grid, as a 7.5kW generator will take care of your equipment and electrical needs. 

However, you still need to ensure you do not cross the maximum wattage limit in the generator, as overloading can result in fires, electrocution, and other health hazards.

Precision and accuracy is the key to a safe experience with your generator. 

Moreover, before purchasing a 7500-watt generator, you need to tick several boxes to ensure you end up with a device best suited for your needs. If you invest hundreds of dollars into an electronic device, it should be worth it. 

Finally, follow the instructions to establish a secure connection between your energy source and the main power panel. These small steps and precautions can save the lives of your loved ones.
