Best 8000 Watt Generators And Above

8000 watts generators are not as standard as other generators with power ratings between 10,000 to 12,000 watts, and 5,000 to 7,5000 watts, because many homes don’t have use for them. They are either insufficient or too much for their electrical needs during emergencies and when they are needed. Therefore, making it a waste of resources.

Here is our compilation of the best generators you can get if you require 8000+ watts generators.

What To Look For In A Portable Standby Generator

Portable generators, regardless of their power rating, have the same functions and similar features. However, you must see some things and ensure that certain features are in place before purchasing them if you want to get the best from your generator. You should ensure that you choose the best time of year to buy a generator as prices can vary wildly. Some of the things to look out for to ascertain that you’re buying a quality backup generator include:


A sturdy frame, where the engine and fuel tank sits, is an essential feature of an excellent generator. You don’t want a generator that can easily fall apart when its engine vibrates, and the screws holding the parts together come loose. Ensure that the screws and bolts, if visible, are tightly done and cannot come off by using your fingers alone.

Also, ensure that the construction of the generator does not make moving the set around a difficult task. One of the pros of a generator is its portability, and its construction is an essential decider of how mobile it is.

Check the construction materials; can they quickly melt under intense heat? Are they strong enough to carry the weight of the engine and other vital parts of the generator? If they are not, avoid such generators. Most generators employ hard plastics and metals for construction; choose the right one for you.

Safety And Monitoring

Does the power generating set comes with some safety features that help to prevent hazards? If not, avoid it. Usually, generators are used outdoors. Therefore, the electrical outlets need protection against water and other electric conductors that may cause electrocution. Choose a generator that will comfortably sit in the shed you may have at some distance away from your home.

Carbon monoxide poisoning is common with generators that are used indoors. There are some new generators that have in-built safety against carbon monoxide. Choose one that automatically shuts off when the carbon monoxide reaches dangerous levels. However, it is generally advisable that you not use generators indoors and have them in a shed about 20 feet from your home, with the exhaust facing away from your home.

CARB Compliance

Generators release some amount of harmful gases, carbon monoxide, into the atmosphere. These gases are detrimental to the environment and reduce the air quality of the immediate environment. To curb the detrimental effect of these exhaust gases, the California Air Resource Board, CARB, has reached an agreement with generator manufacturers that a certain level amount of these gases will be released into the atmosphere. An excess of the agreed level means they are not compliant with the CARB agreement.

Many states in the United States of America have adopted the CARB requirements, and many generator manufacturers who wish to keep selling their products abide by the requirements and regulations. When choosing a generator, reduce your carbon footprint by purchasing generators that are CARB compliant.


What’s the point of a portable generator that is difficult to move around during a power outage, for example? Consider the size and transportability of a generator before you buy it. The power rating may satisfy your need, but how easy will it be for you to get it out when the need calls?

Look out for generators that have strong handlebars for easily lifting the set. You should also consider generators with wheels. Some have two; others have four. They make it easy to move the generating set from one point to another without lifting it entirely from the floor.

Additional Features

Check for extra features on the generator you wish to buy. For example:

  • How many electrical outlets do they have?
  • Are there DC and AC outlets on the generator?
  • What maintenance features does it have? How about safety features?
  • Is it a single or dual fuel generator?
  • What type of fuel you can use.
  • Does it have idle control?
  • Does it have several power outputs?
  • Are you buying one to prepare for a natural disaster?
  • Will you need to run a cord from the generator into your home?

Apart from those concerned with providing electricity, all of these features help improve your experience with the portable generator and ensure easy application of safety measures.

Frequently Asked Questions

Why Buy a Generator?

A generator is essential in emergency situations as they provide electrical power when the grid is out or when you’re outdoors and can’t get access to electricity from the grid. It is a backup source of electrical power that helps homes and offices get work done when conventional electricity is out.

Why are Honda Generators so Quiet?

Honda generators are quiet because the engine is fully covered, restricting the escape of noise to the environment. Usually, a generator makes noise when the engine combusts fuel and maintains its RPM. However, Honda generators are mostly built with inverter technology and such inverter generators increase their fuel efficiency and reduce their noise significantly.

What will a 10000-watt Generator Run?

With a 10,000-watt generator, you can power large appliances and power tools, depending on where they will be used. It will comfortably run an air conditioner, a refrigerator, a sump pump, a freezer, a furnace, and many other home appliances. Generally speaking, 10,000 watts and above can be considered a powerful generator that has high maximum power output as long as you have a full tank of gas.

What is the Best Generator for Construction Sites?

An industrial generator for construction sites needs an above-average power rating and a larger fuel tank to accommodate longer hours of runtime compared to the ones used at home. Power tools that require enormous starting power are commonly used in construction sites (however some machines like a welder can be run using a 5000-watt generator). Therefore, one of the best generators for construction sites is the Westinghouse WGen 75000DF.

Why go for an 8000 – 12000 Watts Generator, and what Appliances can it Run?

The power rating of the generator you purchase is largely dependent on how many appliances you want to run, usually simultaneously, in your home. generators of 8000 to 12000-watt generators will run most of your essential appliances such as your freezer, AC, furnace, sump pump, and other high-power appliances in your home simultaneously.

Who makes the Most Reliable Portable Generator?

Different people have different experiences with portable generators. Also, the users’ attitude to maintenance determines how reliable a generator can be. However, some of the most reliable portable generators are made by Honda, Predator, and Generac.

Which Generators are the Most Reliable?

It is difficult to determine which the most reliable generator is as different manufacturers employ different technologies from time to time to improve the efficiency and reliability of their range of products. However, it is essential to note that the reliability of a generator largely depends on the user, how often they service their generators, and how well they add oil to the engine.
