Internal EPM set on inverters with meter connection

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 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

Enable Failsafe option 

Advanced Settings ->internal EPM -> Failsafe

This setting is used to give out an alarm (stop inverter generation as well) when the Meter

connection is lost during operation.

It can prevent potential backflow power into the grid when the system loses control.
