6.3.4 Setting Time-of-Use (optional)
Time-of-Use
With the "Time-of-Use" function, you can adjust the charging behavior of the battery to your
electricity tariff. Energy bills are thus reduced and electricity at lower cost can be used. You can
determine in which time range the battery with a specified charging power is operated. At specific
times, this is mostly useful when the battery's state of charge has to take on a certain value or the
tariff situation makes the charging more attractive, regardless of the power at the grid-connection
point. The charging parameters set in the power profile are only limited by the state of charge
(SOC). At times when the "Time-of-Use" function is not enabled, the battery is charged
correspondent to the increased self-consumption for the entire system. The "Time-of-Use" function is
disabled by default and must be enabled 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].
