How big is the generator for an average household?

Typically, 5KW is enough for a home generator. If you can reduce some electrical appliances, 2KW will be enough. \r\nThe specific calculation method based on commonly used electrical appliances is as follows:\r\n1. Power at the level of common household appliances:\r\nMicrowave oven 600----1500 watts\r\nRice cooker 500----1700 watts\r\nInduction cooker 300----1800 watts\r r\nElectric wok 800----2000 watts\r\nElectric water heater 800----2000 watts\r\nRefrigerator 70----250 watts\r\nElectric heater 800----2500 watts\r \nElectric oven 800----2000 watts\r\nSterilizer 600----800 watts\r\nElectric iron 500----2000 watts\r\nAir conditioner 600----5000 watts\r\nAir conditioner 1000W\r\nMicrowave oven 1000W\r\nElectric stove 1000W\r\nElectric water heater 1000W\r\nVacuum cleaner 800W\r\nHair dryer 500W\r\nElectric iron 500W\r\nWashing machine 500W\r\nTV 200W\r\nComputer 200W\r\nHood 140W\r\nVentilator 100W\r\nFlashlight 0.5 W\r\nLighting 50-100W\r\n\r\n2 . Calculation of the power of electrical appliances needed in the event of a power outage\r\nRefrigerator 250W\r\nTV 200W\r\nComputer 200W\r\nLighting 50- 100W\r\nStarter battery box is a type of compressor , and the starting current. is calculated as 2.5 times, so the generator power of the refrigerator is 250*2.5=625W\r\nSo the minimum power of the household generator=200+200 +100+625=1125W, leaving some power available, so a 2KW generator is enough! \r\n3. Calculating the power of commonly used electrical appliances\r\nSome families can add air conditioners, electric water heaters and other equipment to the necessary electrical appliances:\r\nBecause air conditioners are compressors, the starting current of air The air conditioner is also According to the calculation of 2.5 times, a 1000 W air conditioner requires a power ofe 2,500 W generator. Coupled with the 1,000 W power of the electric water heater, plus the 2,000 W power of the essential original electrical appliances.\r\nThus, the generators used in commonly used household appliances are 1125W+1000W+2500W=4625W, which leaves a few spare 5kW generators. that's enough!
