7.1.4.1 Setting Grid Parameters
Procedure
Step 1 Choose Settings > Grid parameters to set grid parameters.
Figure 7-7 Grid parameters
Table 7-1 Grid parameters
Parameter Description
Grid Code Set this parameter based on the grid code of the country or region
where the inverter is used and the inverter application scenario.
Isolation settings Set the working mode of the inverter based on the grounding
status at DC side and the connection to the power grid.

7.1.4.2 Setting Protection Parameters
Procedure
Step 1 Choose Settings > Protection parameters to set protection parameters.
Figure 7-8 Protection parameters
Table 7-2 Protection parameters
Parameter Description
Insulation resistance
protection threshold (MΩ)
To ensure device safety, the inverter detects the insulation
resistance of the input side with respect to ground when it starts a
self-check. If the detected value is less than the preset value, the
inverter does not connect to the grid.
