14.5 Team Mode Interrupted
An interruption of team operation can have various causes. These will be described in this section.
Key switch set to "STOP"
If one of the two Sunny Centrals is switched off, team operation is not possible. The Sunny Centrals
connect individually to the grid.
Emergency shut-off switch actuated
Depending on the wiring option, the emergency shut-off switches of the Sunny Centrals in team
operation are either interconnected or not interconnected. SMA Solar Technology recommends
connecting the emergency shut-off switches of both Sunny Centrals in the team.

– Both Sunny Centrals change to "Emergency shut-off" mode. Neither grid feed nor team
operation is possible.
• Emergency shut-off switches not interconnected, no team operation.

off" mode.
– If the second Sunny Central is the team manager, it willl remain in its current operating mode.
