AC coupled inverter is a type of solar inverter that connects to the AC output of an existing solar inverter. It allows to add battery storage to the existing solar panel without replacing current inverter. Once solar panel generates power, AC coupled inverter works by taking the AC power & converting to DC & then DC power charge the battery, when its full then power access sent it back to the grid.

AC Coupled inverter can be good for who – Have an existing solar system that they want to add battery storage to, do not want to replace their existing inverter, want to be able to back up their home during a grid outage.

AC coupled inverter is best to add battery storage to existing solar system. It’s an easy-to-install inverter & compatible with most solar systems.
