5. Select the button [Active].
6. Select the icon Create new power profile.
7. Enter the name of the power profile in the field Name of the power profile.
8. Select the entry Time of use in the drop-down list Operating mode of the power profile.
9. Enter the target charging power in the field Forced charging power. The power is set
independently of the grid-connection point.
10. Make the time range setting. You can select on which days of the week, in which date range
and at what time the power profile should be valid. Even a power profile independent of the
days of the week, which should be valid on a set date, can be configured. For this, you must
select the the option Independent of days of the week.
11. To temporarily save the power profile and to possibly create other power profiles, select the
'save' icon to the right of the overview Created power profiles. The data are saved
temporarily on this page. The data are only transferred when the page is closed by clicking on
the [Save] button.
12. To assign priority to multiple power profiles, select the desired power profile in the overview
Created power profiles and set the priority by moving the power profile up or down.
13. To save the power profile and to close the page, select [Save].
14. To deactivate a power profile, select the desired power profile in the overview Created
power profiles and then select the entry Inactive from the drop-down list Operating mode
of the power profile.
6.3.5 Setting the Peak Load Shaving Function (optional)
Peak load shaving
With the "Peak Load Shaving" function, you can optimize the behavior of the battery inverter with
respect to the power exchange at the grid-connection point. This is mostly useful when a higher
supply of energy would lead to a higher electricity cost. With the "Peak Load Shaving" function,
certain grid-exchange power outputs to which the battery inverter is adjusted depending on its
power and battery capacity available can be set. Power peaks can thus be avoided.
You can configure times and setpoints for the power drawn at the grid-connection point. When the
loads require additional energy, the battery is discharged and the maximum value is kept constant
at the grid-connection point. This is based on the prerequisite that the battery is sufficiently charged.
At times when the "Peak Load Shaving" function is not activated, the battery is charged or
discharged correspondent to the increased self-consumption for the entire system. The "Peak Load
Shaving" function is deactivated by default and must be activated by creating power profiles.
Procedure:
1. Activate the battery inverter user interface.
2. Log in as Installer.
3. Select the menu User settings.
4. Select [Power profile].
5. Select the button [Active].
6. Select the icon Create new power profile.
