Problems with streaming services

If you use the streaming service in your local network (in which the inverter is also included), there may be interference
to the transfer of data. In this case, the IGMP settings of the inverter can be changed via operating parameters.
• Contact the Service and change IGMP settings in consultation with the Service department.

Set time for detection of communication failure

If communication between the Sunny Island and the SMA Energy Meter or the Sunny Home Manager is interrupted,
the Sunny Island stops after a certain time. Both multifunction relays then switch to the idle state. As a consequence, the
feed-in operation of the PV inverters is stopped.
The time until this communication failure is detected is adjustable.
Procedure:
1. Select System & device control > Point of interconnection.
2. Set the Communication timeout for measured value acquisition of Energy Meter at point of
interconnection to a value between 1 s and 30 s (default value: 2 s).
