Step 2: Select the corresponding meter model in Section 6.5.12.4
Step 3: Select the Section 6.5.11.1 Mode Select as Option 3(Meter in Grid).
Step 4: Select the Section 6.5.3 24H Switch as "Enable".
Step 5: Configure the Section 6.5.11.2 to set the allowed backflow power.
Step 6: Configure the Section 6.5.11.3 to enable the failsafe function
(If necessary).
Step 7: 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 5
OR simply select the mode as "consumption monitor" in Step 3 and skip Step 5-6.
Select EPM Settings from the Main Menu to access the following options:
1. Mode Select
2. Set Backflow Power
3. Fail safe ON/OFF

2. Meter in Load
3. Meter in Grid
4.Consumption Monitor
5. Current sensor
EPM OFF: Functions are disabled
Meter in Load: Solis Smart Meter is connected in the load branch circuit.
Meter in Grid: Solis Smart Meter is connected in the grid connection point

2. Inverter is set as "Grid OFF" in the LCD.
3. CT is connected to the inverter CT port and the CT is placed at the grid side.
·CT Sampling Ratio
This setting is used to define the CT sampling ratio if customer didn't use the
default CT supplied by Solis.
The default CT is 100A:33.33mA (Default ratio is 3000:1)
-> CT Sampling Ratio
YES=<ENT> NO=<ESC>
Ratio:3000:1
CT Link State
