For example, an audio amplifier serves as an inverter as it converts a DC power source into an AC power source that drives a speaker coil, which essentially functions as a linear AC motor. However, the term "amplifier" is used instead of "inverter" because the primary purpose of an audio amplifier is to increase a small audio signal, such as from an MP3 …

An inverter''s primary function is to change the direct current (DC) that is fed into it from your solar panels into alternating current (AC), which your house is able to make use of. This method is taken to a whole new level when a hybrid solar inverter is used, which brings with it a number of benefits, including the following:

When the energy contained in the sunlight strikes the PV cells, it causes an electron to be released, and these electrons flow to form a Direct Current. The DC current created can then either flow to the batteries for storage and later use, or it can be transmitted to the home directly for use in the electrical system.
