SMA sunny home manager - Grid Management Services Setup

☐ 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,
page120).
Procedure:
1. Select Configuration > PV system properties in the page and menu selection.
2. Select the tab Parameters.
3. Select [Edit].
☑ The menu for parameter settings opens.
4. In the area Limiting of the active power feed-in, select the applicable option:
• If limitation of active power feed-in is not required for your system, select no limiting of
the active power feed-in (default setting).
• If limitation of active power feed-in is required for your system, carry out the following
steps:
– To test whether the limitation of active power feed-in is working in the system, select
the option max. xx kW and enter the value 0. Thus, the SunnyHomeManager
immediately limits the active power when the inverters start feeding into the utility
grid.
– 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 PV system
power, select the option Max.xx% of the nominal PV 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 PV system power and enter the value 0.
5. Select [Save].
☑ The data is being 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 diagrams Energy balance - Current and Energy balance - Day, 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.
