The inverter is a static device. It can convert one form of electrical power into other forms of electrical power.

It can be used as a standalone device such as solar power or back power for home appliances. The inverter takes DC power from the batteries and converts it into AC power at the time of the power failure.

A power inverter is used in the power system network to convert bulk DC power to AC power. i.e. It is used at the receiving end of HVDC transmission lines. This inverter is known as a grid-tie inverter.
