AC
AC voltage (Alternating Current) is the most common type of electrical voltage used in power and photovoltaic systems. It alternates polarity periodically, allowing efficient energy transmission over long distances. In PV systems, AC appears after the inverter converts the generated DC power.
AC components – such as inverters, grid connection units, protection devices and distribution panels – are designed to handle alternating current safely and efficiently. They ensure stable voltage levels and reliable power feed into the grid or local systems.
