In an AC-coupled system, a grid-tied PV inverter is connected to the output of a Multi, Inverter or Quattro. PV power is first used to power the loads, then to charge the battery, and any excess PV power can be fed back to the grid. | In an AC-coupled system, a grid-tied PV inverter is connected to the output of a Multi, Inverter or Quattro.
