Buyers guide

The next features can help you choose a 10000 watt generator

Fuel tank capacity

When choosing, it is important to understand that a generator with a large fuel tank volume will work without interruption for a very long time. Obviously, the smaller the tank volume, the shorter the operating time. An 8-gallon generator tank will run for an average of 12 hours at 50% load. This will give you the ability to receive uninterrupted power for those important tasks that you may have.

Running time

Talking about the operating time, you need to consider that it depends on the capacity of the fuel tank and how economical your generator is. Most 10000 watt generators can run for up to 13 hours at 50% load. Yes, there are undoubtedly models that work all day and even 72 hours, but they are rare on the market and, moreover, the price tags are incredibly high. Also, it is worthwhile to understand that generators are not eternal, respectively, over time, they become unusable. If you use a generator all the time and operate almost 24 hours a day, its operating time will be drastically reduced.


90% of generators are equipped with a carbon monoxide detector that automatically shuts off the engine if the amount of gas exceeds the norm. Some generators are still automatically shut down during an emergency, such as a system overload. All users must take precautions when using the generator. This will help avoid electric shock. Also, I strongly advise you to always turn on the generator outside the home. Moreover, it is important to connect it correctly to avoid overloading.

Understanding starting, running, and surge wattage

Starting, running, and surge wattage are most likely the first expressions you will come across when choosing a generator. However, it is very important to understand what these metrics are if you want to choose a generator that will work well for your needs and will not be a waste of money.

So, let’s figure out what it is. First, running wattage is the amount of electricity necessary to run your appliances continually. That is, after starting, the amount of energy that powers your devices during use will fall under the characteristics of running watts. This indicator is usually lower than the starting one, but it is reliable and constant, guaranteeing a minimum chance of interruptions.

Second, starting and surge watts represent the additional amount of electricity needed for 2-3 seconds to start electric motors commonly found in household appliances. These, traditionally, include ovens, refrigerators, or other large devices. It is important to understand that this is such a peak value that appears only at startup and then stabilizes by transforming into running watts.

What can you run on a 10000 watt generator

In the modern world, people have learned to animate any devices with the help of electricity. Yes, some of them are more demanding, some use less energy. If you are still wondering what can power my 10000-watt generator, the answer is everything.

Seriously, this is not even a joke. Nowadays, most electrical appliances are incredibly optimized, and if you are planning to go outdoors with a generator – go for it! Such a device will be able to power the refrigerator, TV, stereos and much more without any problems. Most 10000 watt generators, at 50% load, can run for more than 10 hours, which is more than enough. However, I recommend calculating the power consumption of your devices to avoid confusion. Let’s take a look at several devices and the amount of energy they consume:

  • Refrigerator – up to 800 watts
  • Toaster – 1000 to 1700 watts
  • Microwave – about 5000 watts
  • Table lamp – 150 watts on average
  • Central air conditioner – from 2000 to 4000 watts
  • Water pump – on average 1000 to 2000 watts

How loud are 10000 watt generators

Speaking of loudness, it depends on the specifications of the generators because they can be as loud as possible or very quiet. Typically, inverter generators have a range of 50 to 60 dBA. On the other hand, 10000 watt propane generators can range from 70 dBA to about 80 dBA. To more accurately understand this number, you can find it on the product packaging or directly in the user manual, or on the body of the unit. It is better to choose a generator that is equipped with an internal silent muffler. Some generators are fully enclosed or rubber mounts to minimize noise.

Tips for generator maintenance

Maintaining a generator is not difficult. In fact, anyone can do it with very little knowledge and understanding. Let’s take a look at the basic tips and rules.

Correct oil change

Any generator needs a very regular oil change for the correct operation of all components of the system. It is recommended that this procedure be done every 50-200 hours of operation, based on how often you use the generator. For example, more modern models may require fewer oil changes because they burn cleaner than older models. But if your generator is operating in an environment with a lot of dust or dirt that might mix with your oil, you may need to increase the number of times you change the oil.

Maintaining cleanliness as the key to success

The rotor and stator, which are located inside your generator, work together to generate electricity. During operation, rotors and stators usually collect dust, debris, and other contaminants and must therefore be kept clean. A large amount of dirt and dust on the rotor and stator will significantly reduce the efficiency of their work.

To remove unwanted dust and dirt, the air filters in the generator must be cleaned. In addition, experts recommend checking the air filter for dust on a weekly basis.

Correct launch

The generator, even under the condition of rare operation, must start correctly and correctly. Therefore, it is recommended to regularly run it just like that to check its serviceability. You need to make sure in advance that it is lubricated with oil and the carburetor works well.

Avoid old fuels

Often, experts recommend draining the generator tank after each use. This procedure ensures that you are using clean and efficient fuel. Plus, this process protects your equipment from erosion and damage from the inside.

Never use fuel that has expired, it is much easier to spend extra time and buy quality fuel that will not let you down in a minute when you need the generator to work.

Proper storage of the generator

In order to prolong the life of a unit, there are certain precautions after each use. It is important to double-check that the fuel lines are empty and free of fuel residues. All equipment must be stored in a cool, dry place that is also ventilated. This will help reduce rusting and extend its life.

How to safely use 10000 watt generators

Safe connections

The correct use of the generator is the key to the success and safety of you and your loved ones. Therefore, there are several rules that must be followed in order for everything to go well. First, it is important to correctly size the generator to suit the electrical loads you intend to supply.

Second, it is very important to use the transfer switch correctly. Using a portable generator in conjunction with a manual transfer switch, a rugged electrical device, is the safest way to use a portable generator for back-up power at home. The generator should be connected to the transfer switch with a thick, durable cable that plugs into an outlet installed outside the house. The cable should run neatly from the wall outlet to the transfer switch. Electricity from the generator passes through the generator set cord, to the outlet, through the internal cable, to the transfer switch and its circuit breakers, to the various circuits you need, safely.

Dangerous discharge

It’s no secret that generators produce large amounts of carbon monoxide. Remember once and for all, the generator cannot be turned on indoors, be it a residential building, a basement, a garage, or an office. Carbon monoxide, when concentrated, forms a deadly mixture that is incredibly dangerous to humans and animals. Based on this, the generator exhaust pipe should be directed away from the house.

Most modern generators are equipped with CO detectors that shut off the machine before CO builds up to the point where it becomes fatal. Buying such a generator is a great idea, although it will cost many times more.

Choosing the right fuel

When handling the generator, remember that it must never be refueled while hot after operation. Also, although this is obvious, still, in no case should fuel be stored near hot objects, under the sun, etc.

By the way, some quiet 10000 watt generators have a muffler that tends to heat up. Therefore, when using, be extremely careful. It is also important to maintain the correct fuel supply. The best option would be to use a fuel stabilizer that slows down the chemical decomposition of the fuel.
