Preset grid codes
The inverter has preset grid code settings for numerous countries. The installation grid is
set with parameter135.01 Grid code.
Note: The inverter will not operate without a valid grid code setting.
When a grid code is selected, all the necessary parameter settings are set to match the
grid requirements. The grid code settings affect parameters in the following groups:125
FRT support curve,126 FRT tripping curve,130 Limits and135 Grid monitoring. The
parameters include, for example, tripping limits for under- and overvoltage and under- and
overfrequency, initial connection delays, a variety of reconnection delays, anti-islanding
settings, fault ride-through settings, power limitation settings, and MPPT recovery settings.
Usually the grid code is not changed during the lifetime of the inverter.
If you need to change the grid code, note that changing the parameter135.01 Grid code
always overrides manual changes performed on the above-mentioned parameter groups.
The ready-made parameter settings that are installed by the selected grid code can be
modified according to the local requirements after the grid code is set. See more details in
the section Customizing grid code settings.
Customizing grid code settings
To change the grid code-related parameter settings (parameters in groups125 FRT
support curve,126 FRT tripping curve,130 Limits and135 Grid monitoring), follow this
procedure:
Disable the inverter
1. Enter the Parameter menu.
2. Select189.01 Inverter operation and press Edit.
3. Change the value from Enabled to Disabled and press Save. After a short period, the
inverter stops running and it is possible to change the parameter values.
Customize settings
1. Enter the parameter list: Menu
→ Parameters → Complete list.
2. Check that you have set a grid code with parameter135.01 Grid code.
3. Make required changes to the parameters in groups:125 FRT support curve,126 FRT
tripping curve,130 Limits and135 Grid monitoring.
Enable the inverter and save the parameter changes to permanent memory
1. Select189.01 Inverter operation to Enable.
2. Save parameter values by setting the parameter196.07 Param save.
