If your inverter needs to have the grid standard changed, you must first turn the grid OFF so that the inverter ceases production.  Otherwise, the new grid standard setting will not be saved.

  1. Under Advanced Settings, select the second option, "Grid On/Off" - Select "OFF" and press "Enter." Wait until the inverter stops generating.
  2. Return to "Select Standard" to choose a different grid standard.  If a custom grid standard is required, select "UserDef" and apply the specified settings.  Refer to how to set a custom User-Defined grid standard for additional guidance.
  3. After you select the desired grid standard, make sure that you "Save and Send."
  4. Return to "Grid On/Off" - Select "ON" and press "Enter."  Verify that the inverter resumes operation.
