For limiting the export on the inverter, depending on the exact model of the inverter, customers can use use the internal EPM (Export Power Limit) function and have a meter communicating with the inverter (see attached meter compatibility list).

For consumption monitoring select the appropiate option and make sure the meter is installed on grid
Main Menu-> Advanced Settings (password 0010)->Internal EPM -> Mode select-> Consumption monitoring

For limiting the export to the grid

Step 1

Determine if meter connection is Meter in Grid or Meter in Load, and select appropriate Mode Select.

Advanced Settings (password 0010)->Internal EPM -> Mode select

Step 2

Set backflow power value to desired maximum value to be exported.

Advanced Settings ->internal EPM -> Backflow Power

Step 3
