What Will A 10000 Watt Generator Run?

Commonly found on construction sites or homes that face inclement weather, power generators are a vital tool for running a lot of equipment in and out of emergencies.  A generator creates electricity, which can then be used to power items such as fridges and power tools. Each 1000 watt generator has various outlets and features that help run these appliances and can be gas or electric started depending on the model used.


Choosing Quality 10000-Watt Generator

Generator Size vs. Power Needs

Before picking a generator, think about what kind of things you need to power. Is it just your fridge, freezer, and AC? Is it some tools around your farm or job site? Answering these questions and knowing how much storage space you have can give you an idea of what size you need. If you will be alone in transporting your generator, also try to choose a lighter model or one with a wheel and handle system.

Power Output

Peak and rated power output are vital in determining what appliances your generator is compatible with. Combine the composite wattage of all the required appliances and the highest starting wattage to know how powerful a generator you need. If math is not your strong suit, consult a professional, or use this guide.

Generator/Fuel Type

The two most common fuel types for power generators are propane and gas. Most generators can either be single or dual fuel generators that are started by either electric or gas-powered. Depending on the size and design of the generator, it may also be battery powered or portable, which can really come in handy.

Noise Level

For those with neighbors or strict sound rules, getting a relatively quiet generator is important. Read the description or label of your desired model to see how many decibels it has; the fewer, the better for those looking to sleep with it running. Typically, most generators sit at around 75 dB or so.

Fuel Tank Capacity/Runtime

If you want to keep the generator for long periods or while you are asleep, try to find a generator with longer runtime and a larger tank. 10-12 hours should be enough for those looking to sleep and maintain power during an outage or emergency. If you typically sleep less, find out how much you sleep on average and find a generator that runs longer than that.

Fuel Efficiency & Running Cost

If you are confident that you will use your generator multiple times and that it is the right one for you, then it can pay for itself numerous times over. In terms of fuel, gas typically burns better than propane, but propane is cleaner and stores better. Getting a dual is an option for those who want flexibility.

Build Quality & Durability

Generators are an investment item and should be built to last through inclement weather and prolonged use. Make sure to check the materials used and to only buy through reputable sites and sellers. Read the customer reviews carefully and maintain your generator regularly to make sure that you get the most bang for your buck.

Other Features

Power generators come with a variety of outlets to power various appliances and tools; Read the label carefully to make sure that the outlets fit your requirements before purchase. Look for safety features such as auto oil level shut off, overload sensor, heat diversion, or brakes and consider investing in a generator tent to protect it.

Price & Warranty

A warranty is an excellent backup in case of an accident, and generators are often covered for up to 3 years or so. In terms of cost, a small, simple generator with fewer features will typically cost less. A generator can cost anywhere from $300 to $5000 or so, not including installation or maintenance costs over time.

What Size Generator Do I Need?

To get the most for your money, we recommend getting the smallest generator that suits your needs. Think carefully about what you want to power and calculate the wattage of everything. While a 10000-Watt generator can run almost anything, you can use this handy guide if you are still unsure.


Hooking Up a 10000-Watt Generator

Before purchasing a generator, reconfirm the size, wattage, and amount of storage available. Either arrange for the delivery person to bring it to your desired spot or bring another person to help you carry it; make sure to keep your generator running in an open space and away from windows.

Pick up the correct type of fuel and make sure you have a surplus on hand for top offs or changes. Consider investing in a generator cover or tent if you are using it outside. Once your new power generator arrives, make sure that you have enough room to work with and that you have the right tools and safety equipment available on hand.

If you do not have a transfer switch installed, hire an electrician to install that along with the generator; this can cost between $300 and $1000 depending on location and needs.

How to set up a 10000-Watt generator at home

Once you have a transfer switch in place, do the following:

  1. 1
    Connect the generator’s 120V/240V to the transfer switch.
  2. 2
    Turn the transfer switch from 'line' to 'generator.'
  3. 3
    Turn the generator on.
  4. 4
    Turn every necessary item on one at a time.

How to set up a 10000-Watt generator to an RV

You will need:

  • A grounding rod
  • A pole driver
  • Copper wire
  • Cover or generator tent
  1. 1
    Drive the rod into the ground a safe distance from the RV.
  2. 2
    Connect the wire from the rod to the generator
  3. 3
    Route the generator’s exhaust away from the RV.
  4. 4
    Plug the RV’s generator connector cable into the generator.
  5. 5
    Turn on the generator.
  6. 6
    Cover with a tent if necessary.

How to Run a 10000-Watt Generator Safely

  • Never run the generator in an enclosed space or near windows.
  • Do not run it in the rain – cover and ventilate it.
  • To refuel, turn off the generator and let it cool fully – refill to the line or manual instructions.
  • Stock up on fuel, add stabilizers to spare cans and store them in dry places away from heat sources.
  • Never connect the generator to a home outlet – a transfer switch is vital.
  • Clean and maintain the generator regularly.
  • Change the fuel and spark plugs regularly.

Frequently Asked Questions

What type of fuel is more efficient and budget-friendly, gas or propane?
Propane is cheaper and easier to get hold of in the long run. It also burns cleaner and stores better than gas.
What type of maintenance is needed for a 10000-watt generator?
General and technical maintenance are required regularly for your generator to remain in peak condition. Cleaning, part inspections, topping off and powering up every quarter, and changing the oil and spark plugs are all essential tasks when it comes to maintaining a generator.
How long do 10000-watt generators last?
With regular cleaning and maintenance, a 10000-watt generator can last 1,000 to 2,000 hours or over 20 years.
Are these generators expensive to run?
This depends on what kind of generator your purchase; one with fewer features is typically cheaper. However, your generator will pay for itself over time with regular use.
How noisy is a typical 10000-watt generator?
This depends on the model and brand, but most generators sit at around 75 decibels or the sound of a distant vacuum.
What are the top brands for 10000-watt generators?
Honda, Durostar, Briggs and Straton, Pulsar, PowerPro, and Duromax are just some of the quality generator brands out there.
What is the importance of a generator transfer switch?
A generator transfer switch prevents back-feed electricity from backfiring and going in the reverse direction. This is dangerous and can damage wiring or even harm electricians and other workers who operate the lines.

Conclusion

Choosing and installing does not have to become a huge struggle, and it does not have to cost the earth. Pick the smallest generator you can for your needs, and, with proper care, it can provide you with power for years to come. While we do like all of the options on this list, we would have to recommend the Firman H08051 overall.
