Will a 9000-watt generator run a house?

This will depend on a number of different variables, such as the size of the house and how much electricity is used. You can use an online calculator to find out how many kWh a 9000-watt generator can handle in a day, and then compare that to your house’s daily usage. For example, if you have an 1800 square foot home with all-electric appliances, including central heating and air conditioning, your house will likely require about 6000 kWh per month or 12000 kWh per year.

  • 1000-watt generators operate at their peak efficiency between 70% and 90% of the time.
  • 3000-watt generators (the largest size available in the US) operate at their peak efficiency between 58% and 72% of the time.
  • 5000-watt generators (the largest size available in the US) operate at their peak efficiency between 45% and 58% of the time.

What can I run with a 9000-watt generator?

Although a new generator is recommended, it will also be helpful to look at your current power usage. For example, if you have an older refrigerator that has a 7-10 year life expectancy, then switching to all-electric appliances could help conserve electricity and lessen your carbon footprint.

For example, a sump pump, freezer, refrigerator, and furnace can take up to 4,000 watts. If you consider adding a few lights, TV, and microwave oven and a 7,500-watt unit will be working near its continuous capacity. A 9,000-watt standby generator would likely be able to also take the load of a 1-ton air conditioner.

What will a 10,000 to 13,000-watt generator get me?

If you’re just looking to run a few more appliances, then you might want to invest in a 10,000- -watt generator. These units generate up to 5500 watts or 7200 watts with their auxiliary use. Compared with the above, you could run a well pump, electric hot water heaters, and larger A/C unit.

Those power levels are sufficient for many typical households and small businesses. In addition to appliances, power tools like drills and wrenches can be run on standby generators. If you’re interested in running electronics and video game consoles, you should check out 15,000-watt – or higher – generators.

What will a 16,000 to 22,000-watt generator get me?

Most people want to have all the essentials, like power and water, available during a disaster. This is why generators in this range are so popular. Transfer switches that manage power can be used to run high-voltage appliances. Transfer switches are connected to the generator and they provide a safe way to transfer power between the generator and other electrical sources. It’s important to understand that owning a generator doesn’t mean you’ll be able to produce as much power as the electric company. Many people in a house won’t know the power is out, even if they’re using a generator of this capacity but remember that it will run for a limited amount of time so be sure to be conservative in your energy consumption when the generator kicks off.

What is the difference between portable and stationary generators?

Portable generators are generally much smaller, lighter, and more portable than stationary models. They’re also less expensive, but more difficult to set up due to the increased size of the generator. Portable generators don’t have a permanent location like a stationary model does, so you need to be sure you have access to electricity while installing it.

What about using a diesel generator?

Diesel generators require the use of natural gas, which is prone to freezing. The engine in the generator runs on fuel oil. Diesel generators are much more expensive than an electric or gas-powered unit. Diesel engines can also be more likely to leak harmful gases into the environment than gasoline engines, emitting sulfur dioxide and nitrous oxide. Because gasoline-powered generators do not produce carbon dioxide when running, they are a much better choice for the environment.

Benefits of standby generators

  1. Clean air:  It’s better for the environment to run a generator on standby than to use it every day. Generators produce only warm air and cooler incoming air offsets that heat.
  2. Longer term savings:  Most generators are rated for 20 hours of continuous operation, but running it overnight and switching off in the morning usually doesn’t cause any noticeable dew point drop – assuming you don’t live near a desert area.
  3. Heat recovery:  Depending on the type of unit, you may be able to recover some of the heat produced by the generator during use. When generating electricity with a heat source, the best temperature to operate your appliance at is 27 degrees C or above. For example, a refrigerator will operate best at 32 degrees C if set at its coldest setting. Using a heat recovery system, you can prevent some of the heat from escaping while still running your appliances for extended periods.
  4. Power quality:  Most manufacturers will include a voltage regulator with generators, but check on their specifications to see which voltage it will accept. If you have a large surge event, the voltage regulator may trip out and cause the generator to stop.
  5. More appliances can be used:  Although there are exceptions (check your specific model), most generators are able to power many of your standard household appliances simultaneously. In order to do so, they will need to be on a surge protector (and plugged into other outlets). Some of the types of appliances you can run at the same time with a generator include LED lights, a fridge, microwave oven, laptop or desktop computer, TV, and coffee maker.
  6. Convenience and safety:  It’s easier to flip a switch to power your home, than it is to manually connect a generator. This is especially true if you have a small generator and need to transport natural gas or propane tanks. It’s also safer, as you don’t have to worry about spilling gasoline or other fluids.
  7. Quality of the generator:  Generators from reputable manufacturers will generally be better quality than knock-offs, which may not last very long.
