6.5.12.2 Backflow Power
->Set Backflow Power
Figure . Set the power 6 23 backflow
The setting is used to define the allowed export power into the grid.
For Solis single phase inverters, please select "1PH Meter" and then select the
corresponding meter model.
6.5.12.4 Meter Select
The setting is used to define the correct meter that is connected to the inverter.

6.5.12.3 Fail safe ON/OFF
This setting is used to give out an alarm (stop inverter generation as well) when the CT/Meter
connection is lost during operation.
It can prevent potential backflow power into the grid when the system loses control.
Figure 6.24 Set the Fail Safe ON/OFF
YES=<ENT> NO=<ESC>
Fail Safe Set:ON
It is only mandatory to turn on this function when the inverter is installed in UK due to the G100
regulation. For other regions,customers can enable or disable the function as they desire.
NOTE:
When the failsafe function is ON and CT/Meter is disconnected somehow,
the inverter will stop generation and give "Failsafe" alarm on the LCD.
When the failsafe function is OFF and CT/Meter is disconnected somehow,
the inverter will keep the output power as the last moment when the
CT/Meter is still connected. After a restart, the inverter will output at full
power without limit.
YES=<ENT> NO=<ESC>
Power:-00000W
NOTE:
Positive values indicate the amount of power is allowed to export to the
grid.
Negative values indicate a more strict control to limit the export power in
advance thus ensuring exact no power is feeding into the grid.

6.5.13 External EPM Set
Figure 6.26
->5G-EPM
Others-EPM
This setting should only be turned on when Solis external EPM device is used.
Two options are available：5G-EPM and Others-EPM.
5G-EPM Failsafe Option should be turned ON when 5G series EPM device is used
Others-EPM Failsafe Option should be turned ON when 2G series EPM device is used
Only one option can be activated each time.
6.5.14 Restart HMI

This function is applicable by maintenance personnel only, wrong operation
will prevent the inverter from reaching maximum power.
6.5.15 Debug Parameter
This function is used for manufacturer maintenance personnel only.
6.5.16 DSP Update
The function is used for update the DSP.
This function is applicable by maintenance personnel only, wrong operation
