4. Select [Save and continue] after each step up until the step Configure grid management
service.
5. Make the settings as described in the following.
Setting the connected line conductors
• In the tab Feed-in management, select the line conductor to which the inverter is connected
from the drop-down list Connected line conductors.
Making settings for systems with a higher unit (e.g. SunnyHomeManager)
1. Set Feed-in management at the grid-connection point to [Off].
2. Set System control and power limitation to [On].
3. In the drop-down list Operating mode active power, select the entry Active power
limitation P via system control.
4. In the drop-down list Operating mode for absent system control, select the entry Use
fallback setting.
5. In the field Fallback active power P enter the value to which the inverter is to limit its
nominal power in case of a communication failure to the higher unit at the end of the timeout
time.
6. In the field Timeout, enter the time that the inverter is to wait before it limits its nominal power
to the set fallback value.
7. If, in the event of a 0% or 0W specification, the inverter is not permitted to feed small amounts
of active power into the utility grid, select the entry Yes in the drop-down list Grid
disconnection for 0% feeding. This ensures that in the event of a 0% or 0W specification,
the inverter disconnects from the utility grid and does not feed in active power.
Making settings for systems without higher-level unit (e.g.
SunnyHomeManager).
1. Set Feed-in management at the grid-connection point to [On].
2. Enter the total PV array power in the field Nominal PV system power.
3. In the drop-down list Operating mode of active power limitation at the grid-connection
point, select whether active power limitation is to be performed via a fixed specification in
percent or in watts.
4. In the field Set active power limit at the grid-connection point, enter the value to which
the active power at the grid-connection point is to be limited. The value must be set to 0 for
zero export.
5. Set System control and power limitation to [On].
6. For system control and power limitation based on set default values, select the entry Act.
power lim. as % of Pmax or Active power limitation P in W and enter the respective
default value.
7. If the inverter itself is to limit the active power limitation to the grid-connection point, perform
the following steps:
• In the dropdown list Operating mode Active power, select Act. power lim. via PV
system ctrl.
