How big of a generator do I need to run my whole house?
To determine the size of standby generator you’ll need, first identify which appliances and electronics you want to keep running in the event of a power outage. Then, find out the wattage requirements for each of those items. (Hint: most appliances and electronics will have a label indicating their wattage).
Add a safety buffer of 1.25 kilowatts to the kilowatts to provide for future power requirements. For your residence, this is the minimum Generator Capacity. Your house will need at least an 18-22 kilowatt generator if your generator’s minimum capacity is 17.5 kilowatts.
Running even the most vital home appliances, such as the freezer and the pump for your well, may be done with a generator that is rated between 5,000 and 7,500 watts. All of these appliances may be powered simultaneously by a 7500-watt generator.
