To run a whole house with a generator it's recommended to have a 15,000 watt to generator.

However the actual wattage of the generator you need depends on your usage.

But a 15,000 watt generator is best for a whole house to ensure you have enough wattage.

A 9,000-watt portable generator can run one of the following combinations, but not both at the same time:

Refrigerator, microwave oven, electric stove and dishwasher, OR. Central AC in smaller homes, washing machine and iron.

The cost of a whole house generator ranges from $2,000.00 to $4,000.00 depending on the wattage and size of the whole house generator.

Then if you have the whole house generator installed professionally the costs go up another $1,000.00 or so.

If you are not sure on how to correctly wire the whole house generator with the transfer switch then having a professional do the job is what you should do.

You don't want the generator to back feed electricity into the power grid and injure or kill a lineman.

I would always have a whole house generator wired by a professional to ensure it's installed correctly and to ensure it works properly.

When the power goes out the generator should start automatically and power the house.

As a homeowner, buying a generator could spare you financial losses, like food spoilage, when power outages strike.

Also, if you work from home, a standby generator is a solid investment, as it ensures you won't suffer a loss of income due to circumstances outside your control.

I currently have a portable generator that runs off of gasoline and I plug it into the house and have a breaker switch that I turn off that comes from the meter and supplies the breaker box with power.

Then I switch on the breaker that is being fed from the generator to supply power to my house.

I work from home so having a generator is important and worth it.

I keep gasoline on hand for it and run it often to ensure it keeps working.

When I can though I plan to have a whole house generator installed that runs off of natural gas.
