Grid Connected Inverter
  Renewable energies need to convert to AC source in order to connect to the grid. Inverter is used to convert DC to AC. For inverter-based distributed generation systems, the inverters are connected to the existing grid. Therefore, Grid-connected system does not require the battery bank and has become the primary application for high power systems. The main purpose of the grid-connected system is to transfer maximum energy into grid with a unity power factor.
