4. Select [
Save and continue
] after each step up until the step
Grid management service
.
5. Make the settings as described in the following.
Make the settings for systems with external setpoint
1. In the tab
Active power mode
set the switch
Active power setpoint
to [
On
].
2. In the drop-down list
Operating mode active power setpoint
, select the entry
External
setpoint
.
3. In the drop-down list
Fallback behavior
, select the entry
Apply fallback values
.
4. In the field
Fallback value of the maximum active power
enter the value to which the
inverter is to limit its nominal power in case of a communication failure to the higher control
unit at the end of the timeout time.
5. In the field
Timeout
, enter the time that the inverter is to wait before it limits its nominal power
to the set fallback value.
6. If, in the event of a 0% or 0 W 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% active power setpoint
. This ensures that in the event of a 0% or 0 W
specification, the inverter disconnects from the utility grid and does not feed in active power.
Make the settings for systems with manual setpoint
1. In the tab
Active power mode
set the switch
Grid connection point regulation
to [
On
].
2. Enter the total power of the PV array in the field
Nominal system power
.
3. In the drop-down list
Operating mode active power setting
, 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
, enter the value to which the active power at the point of
interconnection is to be limited. The value must be set to
0
for zero active power.
5. Set the
Active power setpoint
to [
On
].
6. Select the entry
Manual setpoint in %
or
Manual setpoint in W
for manual specification
and enter the respective setpoint value.
7. If the inverter itself is to control active power at the point of interconnection, perform the
following steps:
• In the drop-down list
Operating mode active power setting
, select the entry
External
setting
.
• In the drop-down list
Fallback behavior
, select the entry
Apply fallback values
.
• In the drop-down list
Grid disconnection for active power setpoint of 0%
select the
entry
No
.
9.12 Set reactive and active power characteristic curves
9.12.1 Setting the Q(V) characteristic curve
The characteristic curve is preset according to country data set. You can make adjustments via
parameter settings. Coordinate the configuration with your grid operator.
The basic procedure for changing operating parameters is explained in another section (see
Section 9.9, page 76).
