A solar inverter or photovoltaic (PV) inverter is a type of which converts the variable (DC) output of a into a (AC) that can be fed into a commercial electrical or used by a local, electrical network. It is a critical (BOS)–component in a , allowing the use of ordinar. Fundamentally, an inverter accomplishes the DC-to-AC conversion by switching the direction of a DC input back and forth very rapidly. As a result, a DC input becomes an AC output. [pdf]
