Scenario 1. Only Function 1 is required
Step 1: Refer to Section 4.3 to connect the smart meter on the grid side or load side.
Step 2: Select the Section 7.5.11.1 Mode Select as Option 2(Meter in Load) or
Option 3 (Meter in Grid) accordingly.
Step 3: Configure the Section 7.5.11.2 to set the allowed backflow power.
Step 4: Configure the Section 7.5.11.3 to enable the failsafe function (If necessary).
Step 5: Configure the Section 7.5.11.4 to modify the work mode (If necessary).
Scenario 2. Both Function 1 and 2 are required
Using a Smart Meter:
Step 1: Refer to Section 4.3 to connect the smart meter on the grid side.
Step 2: Select the Section 7.5.11.1 Mode Select as Option 3(Meter in Grid).
Step 3: Select the Section 7.5.2.2 24H Switch as "Enable".
Step 4: Configure the Section 7.5.11.2 to set the allowed backflow power.
Step 5: Configure the Section 7.5.11.3 to enable the failsafe function (If necessary).
Step 6: Configure the Solis monitoring system (Please refer to the manual of monitoring
device).
If customer does not want to enable the export power control function, please change
the "backflow power" to the max output power of the inverter in Step 4 OR simply
select the mode as "consumption monitor" in Step 2 and skip Step 4-5.
Select EPM Settings from the Main Menu to access the following options:
1. Mode Select

7.5.11.3 Fail safe ON/OFF
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.

Fail Safe Set:ON
Figure 7.27 Set the Fail Safe ON/OFF
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.
