What size generator should be used for general household use?

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 watts

Induction 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=625W

So, 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 !
