Requirements:
☐ The BLUETOOTH link between all devices of the system must be good. You can check the
connection quality with Sunny Explorer (see Sunny Explorer user manual). To improve the
wireless connection between the BLUETOOTH devices, use the SMA radio-controlled socket as
a repeater if necessary.
☐ The feed-in meter must comply with the requirements (see Sunny Home Manager installation
manual).
☐ With all inverters, the parameter Operating mode active power must be set to the value
Active power limitation P via system control (see Sunny Explorer user manual).
☐ You must have the user role Installer or PV system administrator (see Section 13.1 "Users
and User Rights", page 108).
Procedure:
1. Select Configuration > PV system properties in the page and menu selection.
2. Select the tab Parameters.
3. Select [Edit].
☑ The menu for setting parameters opens.
4. In the area Limitation of active power feed-in, select the applicable option:
• If limitation of active power feed-in is not required for your system, select No limitation of
active power feed-in (default setting).
• If the grid operator requires limitation to a maximum active power in kW, select the option
Max. xx kW and enter the maximum permitted active power in kW.
• If the grid operator requires limitation to a percentage of the nominal system power, select
the option Max. xx % of nominal system power and enter the required percentage.
• If the grid operator requires limitation of the active power feed-in to 0% select the option
Max. xx % of nominal system power and enter the value 0.
5. Select [Save].
☑ The data is transferred. This can take up to five minutes.
6. To display the active power limitation, select Energy balance > Current or Energy balance
> Day in the page and menu selection.
☑ In the Energy balance - Current and Energy balance - Day diagrams, the specified
limitation of active power feed-in is displayed as a red line. If the PV production exceeds
the specified threshold, a blue area is shown above the red line as a maximum, and this
corresponds to the current self-consumption.
Testing the active power feed-in limitation
Before you enter the value given by the grid operator, you can test whether the limitation
of active power feed-in works properly in your system.
• First enter the value 0. Thus, the Sunny Home Manager immediately limits the active
power when the inverters start feeding into the utility grid.
