4. In order to change the stop time of the generator after the maximum number of start attempts has been exceeded,
select the parameter Idle time after generator error / 234.11 GnErrStpTm and set to the desired stop time.

8.5 Setting the Time Control

The time control controls up to two multifunction relays according to the set times.
Procedure:
1. Log in to the communication product as Installer (see the user manual of the communication product) or switch to
expert mode on the Sunny Remote Control (see the Sunny Island operating manual).
2. To set the start date, select and set the following parameters:
Possible settings
Start time for timer 1, date
Start time for timer 1, time
Start time for timer 2, date
Start time for timer 2, time
3. To set the desired running time, select and set the following parameters:
Possible settings
Running time for timer 1
Running time for timer 2
4. To set the desired repetition cycle, select and set the following parameters:
Possible settings
Repetition cycle for timer 1
Repetition cycle for timer 2

8.6 Changing Thresholds for Systems for Increased Self-Consumption

The Sunny Island meets the requirements of the application rule "VDE-AR-N 4105:2011-08 - Power
generation systems connected to the low-voltage distribution network - Technical minimum requirements for the
connection to and parallel operation with low-voltage distribution networks". In the Sunny Island, the application rule is
defined as standard country data set VDE-AR-4105.
In certain countries, the settings may need to be modified for connection of the Sunny Island inverter to the utility grid.
Procedure:
• If the operation of the Sunny Island connected to the utility grid is allowed and an adjustment is necessary, change
the Sunny Island according to the documentation (see www.SMA-Solar.com).
8.7 Changing the Automatic Frequency Synchronization in Off-Grid
Systems
Automatic frequency synchronization enables the use of clocks which use the power frequency as a timer. The
power frequency determines the accuracy of the clock. For power frequencies with constant frequency deviations from
the rated frequency, the time indications will become more and more inaccurate.
Continuous frequency deviations occur in off-grid systems with generators, for example. If the automatic frequency
synchronization is activated, the Sunny Island regulates the frequency deviations over time. As a result, the accuracy of
clocks that use the power frequency as timers is increased.
