Generally, 5KW is enough for a household generator, and 2KW would be enough if some electrical appliances can be reduced.
The specific calculation method based on commonly used electrical appliances is as follows:
1. Common household appliance level power:
Microwave oven 600-1500 watts
< p>Rice cooker 500----1700 wattsInduction cooker 300----1800 watts
Electric wok 800----2000 watts
Electric Water heater 800----2000 watts
Refrigerator 70----250 watts
Electric heater 800----2500 watts
Electric grill Furnace 800----2000 watts
Sterilization furnace 600----800 watts
Electric iron 500----2000 watts
Air conditioner 600 ----5000W
Air conditioner 1000W
Microwave oven 1000W
Electric stove 1000W
Electric water heater 1000W
Vacuum cleaner 800W
Hair dryer 500W
Electric iron 500W
Washing machine 500W
TV 200W
Computer 200W
Range hood 140W
Fan 100W
Flashlight 0.5W
Lighting 50-100W
2. Calculate the power of electrical appliances that must be used during a power outage
Refrigerator 250W
TV 200W
Computer 200W
Lighting 50-100W
< p>The starting battery box is a type of compressor, and the starting current is calculated as 2.5 times, so the power of the refrigerator generator is 250*2.5=625WSo, the minimum power of the household generator is 200+200 +100+625=1125W, leaving some spare power, so a 2KW generator is enough!
3. Calculation of power of commonly used electrical appliances
Some families may add air conditioners, electric water heaters and other equipment to the necessary electrical appliances:
Because air conditioners are compressed Therefore, the starting current of the air conditioner is also calculated based on 2.5 times. A 1000W air conditioner requires a generator power of 2500W. Coupled with the 1000W power of the electric water heater, plus the 2000W power of the original must-use electrical appliances
So, the generators commonly used in household appliances are 1125W+1000W+2500W=4625W, leaving some spare 5KW generators is enough !
