What to Look For in a best 8000 watt generators?

Automatic Start

Whole home generators can automatically start when power goes out. This allows the generator to automatically start supplying power when there is no electricity from the utility. This feature is usually only available on standby generators, and not portables. These systems can provide peace of mind and may be more expensive than the security that your generator will automatically turn on without interrupting vital systems like heating and cooling.

Fuel Source

Generators are generally powered by either gasoline, natural gas or propane.
The majority of portable generators run on gasoline and can generally keep fridges and lights running for several hours. These generators can't be relied upon for long-term power backups, such as when there is no electricity for several days.
Propane and natural gas are used more often for large home-standby generators. These fuels can be used for larger home standby generators as they are cleaner-burning and offer on-demand power.
Solar or battery-powered power sources are an alternative to traditional fuel-powered generators. These machines have different capabilities, and their run time can vary widely. However, they might be the best match for you if your power requirements are less than minimal. They are typically used for camping only, not home.


You need to decide which generator type is best for you: a portable or standby generator. This will help you decide if you just want the lights to stay on or if you need to power other electrical components such as the refrigerator, window, central air conditioner, and the fridge.


Installing home generators requires space. So make sure that you consider the dimensions of all models. You can find generators in a variety of sizes, from smaller units measuring less than 3ft to more large units measuring 5ft or more. A general rule of thumb is that the generator with the highest power rating will be larger.
Be aware that the clearance between your home and generator may be determined by local codes or model specifications. A small generator may require only 18 inches of clearance.


A generator's wattage is the measure of its ability to provide power for whatever it plugs into. This information is crucial to understand about any generator that you are considering.
However, this number does not represent the entire picture. Wattage is made up of three parts: power needed to turn on an appliance and power required to maintain it running. It also includes power necessary to sustain a power surge, which is when regular juice returns to normal and all appliances start to work again. Many appliances use more power for startup than their run energy consumption. You could overload your generator when you turn on appliances and other devices. If the generator can't provide enough power, it could overload. You need to know how many watts your generator can generate, depending on whether it is powering just one item or the whole house.
An increase in generator costs is generally associated with a higher wattage. Most people agree that it's better to have enough power than not to be able to run your fridge or keep cool by a fan.


A warranty is usually included with the purchase of a generator. The warranty covers both labor and parts for most residential inverter and portable generators. For standby generators which can be larger investments, you will usually get a 3- to 52024 warranty period.
Certain warranties may also include travel expenses for technicians to visit the generator and fix it. However, this depends on which manufacturer you are using.


What is the maximum wattage of an 8000-watt generator?

An 8000-watt generator typically has a maximum wattage of 8,000 watts. However, this can vary depending on the brand and model.

How much fuel does an 8000-watt generator use?

This can vary depending on the generator’s size, load, and fuel type. Generally, an 8000-watt generator will use between 6 and 12 gallons of fuel per hour.

How long can an 8000-watt generator run?

This will depend on the size of the fuel tank and the load placed on the generator. A larger fuel tank and a lower load will result in a longer runtime. Generally, an 8000-watt generator can run for up to 18 hours on a full tank of gasoline.

What is the average fuel consumption of an 8000-watt generator?

The average fuel consumption of an 8000-watt generator will depend on a variety of factors, such as the type of fuel used, the load on the generator, and the operating conditions. Generally, a gasoline-powered 8000-watt generator will consume approximately 1.2 to 1.6 gallons of fuel per hour at a full load. A diesel-powered generator will use approximately 0.8 to 1.2 gallons of fuel per hour at a full load.

We decide facts since we are product consulting professionals with extensive expertise. Even so, we maintain and update the list of best 8000 watt generators so the information is correct and up to date.
