SMA HM-20 - Load Balance and Control; Overview Load Balance and Control

13 Visualization of the energy management
SMA Solar Technology AG
Operating manual 95HM-20-BE-en-19
The Legend below the diagram explains the colors used in the diagram and displays the most important overall
values for the time period displayed.
Under Balance, the calculated values for the self-sufficiency and self-consumption quota, which reflect the type of your
own energy supply, as well as other total values for the period shown are displayed.
Representation of limitation of active power feed-in
The dotted red line indicates the maximum active power that may be fed into the utility grid.
• The red dashed line is only displayed on the Day tab in the Generation diagram - and only if you have set a
limitation of active power feed-in for your PV system in SunnyHomeManager.
• If you have limited the active power feed-in to 0%, the red line runs directly on the x-axis of the diagram. Limitation
of the active power feed-in to 0% is only supported by inverters that support the fallback function (fallback: in the
event of a communication failure between the SunnyHomeManager and the inverter, the inverter reverts to an
output power of 0watts). For more information see the inverter manual at www.SMA-Solar.com.
Display with Battery
If a battery inverter is present in your system, you can select between the simplified view without battery data and the
detailed view with battery data. To have the battery data in the diagram and in the Balance area displayed, you must
activate or deactivate the checkbox Detailed view.
Representation of purchased energy limit of the peak load shaving
The blue dashed line indicates the maximum amount of active power that may be drawn from the utility grid.
☐ The blue dashed line is displayed only on the Day tab in Diagram Generation.
13.5 Load Balance and Control
13.5.1 Overview load balance and control
Requirements for displaying the page:
☐ In the SunnyHomeManager system, loads must be available and configured which are either indirectly
controlled by a switching device or which can be directly controlled by the SunnyHomeManager.
The diagrams and tables on this page provide an overview of the operating time, operating duration and energy
consumption of the loads controlled by the Sunny Home Manager as well as the energy mix used (from own PV
generation and grid-supplied power).
For better assessment, the type of load is indicated for all loads (see Section12.4.2, page80). If No assignment is
entered for a load in the column Type of load, this means that no load has yet been assigned to this switching device
(see Section12.3.3, page76).
In the Configuration column, the gearwheel icon takes you directly to the Load properties tab (in the menu
Configuration > Load overview and planning page), on which you can configure different details depending on the
load type, such as the priority of the load (see Section12.4, page78).
