If finding the ideal power for your needs could be confusing, this will surely solves your problems…
Your total power consumption can be calculated by simply adding all the wattage from appliances you’re using at the same time.
Power rating of each appliance can be seen mostly at the back label of it.
Power is rated in watts, some generators are rated in KW (Kilo Watts) which is equivalent to 1,000W (1KW = 1,000W).
For example, a single fluorescent lamp consumes 20w and if you’re using three of them simply multiply it by 3 and you got a total power of 60w.
If you’re using a microwave and rice cooker just simply add the power rating of it.
If you’re running a device with motor such as refrigerator, Air condition or washing machine you’ll need an additional generator power of at least 30%.
This phenomenon is commonly known as the “surge watts”. The power that requires to start running the device in safe condition.
The end results should be at least 70% lower than the generator capacity for safety and maximum power transfer. Although, some prefer half load for longer period of usage.
Adding up the power of all the appliances you need to run on your home during power shortage.
If the total power consumption you need to run your entire household is 7,000w the ideal generator for you is at least 10,000w.
However, most generators have “surge power” rating or “starting watts” in which various appliances are needed to start safely. Appliances like fridge, electric fan, power tools and air-conditions requires additional power to start with.
