“Power” is the most significant entity in anyone’s life. So how can the power of electricity lag behind? But 24-hour electricity supply in India is a dream, except for a few places who boast about having a continuous supply of power. In the rainy season, the scenario changes, but not for the better.
The power supply becomes unpredictable with frequent load shedding at unexpected timings. This is the major drawback of monsoon; you will never know which tree was shaken by the windy rains and which tower and cable were affected by the same.
This state of electricity has proved to be a booster for the growth of inverters, UPS and DG sets in India. But even today many feel that buying an inverter will not only cost them bucks but will also hike their electricity bill. This notion is partially true. Although there are many branded models of inverters/UPS available in the market people buy those which suit their pockets that significantly increase their electricity bill.
To burst this common myth regarding inverters it is essential to let people know about the energy efficiency of inverters.
The efficiency of any system can be defined as the ratio of the output power to the input power.
The efficiency can be identified for 2 operations if the batteries are charged using regular power supply:
Charging Of Batteries:
The inverter takes power from a power supply and charges the batteries. The power taken from the mains is power input and the energy saved in the batteries comprise of the power output. The effectiveness with which the inverter saves 1 unit of power is its efficiency.
As a power backup:
When power from the mains is not available, the power is taken from the battery and supplied to the setup where it is used. Here, efficiency will be the effectiveness with which the inverter draws and uses 1 unit of power.
Some of the energy-efficient inverters available in the market are:
