Optimal selection of generator power: How to make the power selection 1+1>2?


Power optimal selection will enable you to make the best use of you generator, and this document will help you to: 
 
• Use a small and cheap generator that can also meet your requirement.
• Use the generator more efficiently. 
 
Power optimal selection is based on a simple concept that simultaneously using all the electric households is not necessary. When using one electric device, turning off another electric device will help reduce the power needed.  
 
The following questions are needed to be considered: 
 
• Which electric appliances are the most important?
• Does the electric appliance continue to work?
• Do not start all the electric appliances simultaneously.
• Start the electric appliances that need big power in different period of time.
 
In this case, if you start fridge and water pump in different periods of time, you just need 1600 W instead of 1900W. 
 
• If the electric appliance(such as microwave oven) is used for short term, separately use it in that period of time. 
 
Then if you stop fridge and water pump when you use microwave oven, you can save 1500W.
