How big of a generator do I need to buy for my house?
Determine the items you need to use during a longer outage ex.( Fridge, stove, water pump, freezer, furnace, lights) Look at the amps and volts for each item. Volts X Amps =Running watts. By adding them all up gives you the total wattage. After getting the total wattage you can tell which size generator you will require.
