The growing power demand from commercial, domestic, and industrial sectors in developing economies, poor electrification rate in Sub-Saharan Africa, and recent natural calamities in North America are the major factors for growing sales of prime/stand-by power generators around the globe. Generators provide back-up power and classified into prime power and stand-by gensets. Generators runs on different types of fuels such as gasoline, diesel, natural gas, LPG, and others including bio-fuels. Most of the generators (up to 20 kVA) are small gensets and majorly used for back-up power requirements. These small gensets of power rating up to 20 kVA can be classified into stationary and portable generator type. Generators (up to 20 kVA) can be classified in to four power ratings such as 5 kVA, 5-10 kVA, 10-15 kVA, and 15-20 kVA. These gensets of different power ratings are used in residential, commercial, industrial, and telecom sectors according to the power requirements. These gensets in conjugation with main power supply provides back-up power during the time of power fluctuations by the help of self-start-up & shut-down functions.
