Operating manual 43HM-20-BE-en-19
2. In the text field PV system with self-consumption, select whether self-generated PV energy is consumed in your
household (self-consumption).
☑ If you select Yes, the self-consumption of the household is taken into consideration in the load planning and
recommended actions.
☑ If you select No, loads cannot be integrated into the energy management of the SunnyHomeManager. A
corresponding message will appear and you will be asked to either confirm or change your decision.
3. In the area Electricity Tariff , enter the time for which the electricity tariff applies in the input fields From and To.
Tip: Split the night tariff into two tariffs. Configure the first tariff up to 12 midnight. Configure the second tariff from
12 midnight.
4. Enter the electricity tariff that applies to the entered time in the input field Price.
5. If the electricity tariff only applies to specific weekdays, activate the checkboxes with the respective weekdays.
6. If the electricity tariff applies to each weekday, activate all weekday checkboxes.
7. To enter additional electricity tariffs, select and enter the data.

10.4.3 Configuring Limitation of Active Power Feed-In
Requirement:
☐ The parameter Operating mode active power setting must be set to Active power limitation P via system
control or to External specification for the inverters.
NOTICE
Responsibility of the system operator for limitation of active power feed-in
The system operator is responsible for the accuracy of the information on limiting the active power feed-in and the
nominal system power.
• Ask your grid operator beforehand whether you are permitted to use the SunnyHomeManager to limit active
power feed-in (Manufacturer's Declaration "Feed-In Management in Accordance with the Renewable Energy
Sources Act (EEG) 2012 with SunnyHomeManager (SHM) from SMA" available at www.SMA-Solar.com).
• Set the limitation of active power feed-in required by the grid operator. If you are not sure about this, contact
your grid operator.
• Ensure you have correct information on the nominal PV system power. If you extend the system, adjust the
value for the nominal PV system power accordingly.
Ensure that your feed-in meter complies with the requirements.
If your grid operator only allows a certain active power feed-in into the utility grid, the SunnyHomeManager can
monitor and fulfill this requirement by reducing the PV generation of the inverters when the specified limit is exceeded.
This takes into account that in times when your PV system generates a lot of PV power, which is also used directly by
loads - household appliances or a battery that is being charged - a PV power higher than the feed-in limitation is
allowed regardless (dynamic active power limitation).
