Setting Time-Controlled Inverter Operation in Off-Grid Systems
Time-controlled inverter operation enables the regular supply of loads (e.g. electrical heating) during defined time
periods (at weekends). In time-controlled inverter operation, the battery inverter only makes the stand-alone grid
available during the set time period. For the remaining time, the battery inverter remains in standby mode.
1. Activate the user interface of the inverter (see Section 8.1, page 104).
2. Log in as Installer (see Section 8.2, page 107).
3. Select
Device > Operation > Time control
.
4. Set time-controlled inverter operation. First set the parameter
Start date for time-controlled inverter operation
to the required start date.
5. Set the parameter
Start date for time-controlled inverter operation
to the desired start time.
6. Set the parameter
Operating time for time-controlled inverter op.
to the desired operating time.
7. Select the
Repetition cycle for time-controlled inverter operation
/
Repetition
parameter and set it to the
required repetition cycle.
☑ Time-controlled inverter operation is set.
8. To activate time-controlled inverter operation, select the parameter
Time-controlled inverter operation
and set
it
Yes
.
☑ Time-controlled inverter operation is active. If the battery inverter has started automatically under time-control and
you stop the battery inverter, time-controlled inverter operation is deactivated automatically.
8.8
Activate WPS Function
The inverter deactivates the WPS function automatically. When this happens, a signal sounds: long signal (one second)
> break (1 second) > very long signal (3 seconds).
Procedure:
• Enable the WPS function on the inverter. To do this, tap twice on the enclosure lid of the Connection Unit.
☑ The blue LED flashes quickly for approx. 2 minutes. The WPS function is active during this time.
8.9
Switching WLAN On and Off
The inverter is equipped with an activated WLAN interface as standard. If you do not want to use WLAN, you can
switch the WLAN function off and switch it on again whenever needed. In doing so, you can switch the WLAN direct
connection and the WLAN connection in the local network on independently of each other.
Switching on the WLAN function only possible via Ethernet connection
If you switch off both the WLAN function for the direct connection and for the connection in the local network,
access to the inverter user interface and therefore reactivation of the WLAN interface is only possible via an
Ethernet connection.
