TL;DR
An inverter is the power-electronics device in a solar installation that converts the DC electricity produced by panels into the AC power homes and the grid use, while tracking the array's maximum power point and enforcing grid-safety functions under UL 1741. Architectures differ: a string inverter serves whole panel groups from one wall box, microinverters convert at each panel, and power optimizers split the difference.

An inverter is the power-electronics device in a solar installation that converts the DC electricity produced by panels into the AC power homes and the grid use, while tracking the array's maximum power point and enforcing grid-safety functions under UL 1741. Architectures differ: a string inverter serves whole panel groups from one wall box, microinverters convert at each panel, and power optimizers split the difference. It is typically the first major component to need replacement, with 10 to 15 year warranties against 25 for panels.
