Optimal selection of generators: How to make the powerselection 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. For example, you want to use a generator to supply po wer to your household appliances, such as some bulbs, a fridge, a water pump, a TV and a microwave oven. Electric appliances Starting power Operating power Fridge 1600 200 Water pump 1300 800 5 bulbs 300 300 TV 300 300 Microwave ovens 1500 1500 In total 5000 3100 If you think you need a generator with the power of 5000 W just seen from the above table that the total power needed is 5000W, it is wrong. ●Start the electric appliances that need big power in different period of time. In this case, if you start fridge and water pump in d ifferent periods of time, you just need 1600 W instead of 2900W. ●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. Let us have a look at the following example:
