1. An Overall view on Inverters
There are many home appliances and other equipments in a house which are run by electricity.
Inverters are the prime resources to providing the ability of usage of those electrical appliances
during a power outage or shutdown. The backup source can be viable for usage of TV, lights,
kitchen appliances, computer, etc but all depends on the type that has been used. These
specially designed to operate for high-consumption appliances and equipments all together at
once or some depending upon the combination set.
Vital piece of inverters:
It is an equipment which is shaped as a rectangular piece in which a number of batteries are
lined up and attached to each other parallel or series vise. The batteries are the main piece of
inverter without which it is useless. The batteries can be charged by generators, solar panels or
any other power supply source. The batteries should always be kept fully charged so that they
can be utilized during emergencies.
How the inverters function?
They operate by converting direct current (DC) power into alternating current (AC). The
standardized form of current is AC by which all the electrical appliances and equipments are
used whereas the batteries in an inverter can only store current in DC form. The power
supplied to homes by the main power grid of the city is in the form of AC and thus all the

2. electrical appliances are operated under this form. Therefore the batteries need the conversion
of DC into AC.
Uses classification through types:
There are appliances that use higher-energy consumption than others and if too many
appliances of such high-energy are used together, the inverter that is used should be able to
handle such power. True Sine wave inverters are a portrayal of almost the same power as a
main power grid and thus should be used for such high energy-consumption appliances. They
are specifically designed so that they can undertake the operations of high-energy consumption
appliances and equipments. These are quite expensive but very efficient in its performance of
delivering full power.
Most of the times at home, only few home appliances are used and thus doesn’t require much
power. Small equipments like kitchen appliances, lights, etc only use limited amount of energy
and thus Modified Sine Wave inverters are used in these situations. This one is much cheaper
than the True sine wave since high power- consumption appliances such as heaters, ovens, etc
cannot be operated through it; they are not capable of handling such high-energy consuming
appliances and equipments.
Benefits of multiple ratings:
People have different requirements such as the needs of an office and home will apparently be
diverse. There are three fundamental ratings of an inverter and each suitable for a
distinguished purpose. There are few appliances that need a higher power to begin operating
but once it starts running, the power usage decreases significantly. For these kind of appliances,
surge ratings are used which give the high power for commencing period and then slows down
after it. Examples of these are TVs and refrigerators.
There are multiple appliances and equipments which needs relentless power the whole time
they are being used. However, if the inverters are used for a long time, there is a possibility that
they might overheat and eventually shut down.
30-minute rating describes the usage of power not more than 30 minute minutes. For example,
an iron might only be in used for a short period of time and thus 30-minute rating is given to it.
30-minute rating is mostly used when the power-consumption is far below the requirement
than that of continuous rating.
