What is the minimal wattage for a generator to power 20,000 sq foot home?

Answer 1

This would depend on the power consumption requirements.
A typical 20,000 sq ft mansion would require would require something in the area of a 60 KW generator unless you also are powering your private helipad lights, then it would require more

Answer 2

Square footage of a home really doesn't have much to do with the size of the generator but instead the electical appliances is what is considered. For example, your hot water heater, stove, oven and dryer could all be ran with either Gas or Electricity.

To determine what would be required you will need to create a list of all the electical appliances (inside and outside) and including the size and wattage requirements. You should also consider Peak Wattage requirements as some devices (such as AC compressors) will require a surge of power to start the system and then a lower constant supply to sustain it. Your generator should be able to compensate for 90% of the accumlated peak usage on all devices.

Besides the generator, you will need to modify the wiring of your home to allow for the generator to be 'plugged in' and to prevent any electricity you generate from being 'fed back' into the electrical grid.

I am considering the same for my home but luckily I have a brother-in-law who is an electrician and is helping me. I suggest you also find an electrician to assist you in this endeavor.

Hope this helps!

Answer 3

To discover the amount of wattage that you require to run your house, look at the information panel on each of the appliances that you want to run during a blackout situation. (AC,TV, Fridge, stove, what ever you want. Add up the watt rating for each appliance you want to run. Then add up all of the light fixtures that you have, most are rated for over 100 watt bulbs, but most people use 60 Watt bulbs. So the easiest way is to count them and multiply by 100. Add the total appliance load and the total lighting load and multiply by 1.50 to get the overall load with a minimal reserve power to cover the inrush of current for the compressor motors when they kick on. Good luck

Answer 4

Do you mean 2000 sq feet? 20,000 is a mansion

Answer 5

You can't get that answer by sft. You got to add up the power requirements of (at any one time running) electrical appliances /lamps/fans etc. to get the figure.
