Failures
If, when in Team mode, a failure occurs, the Team mode is immediately interrupted, and the Team
contactor is disconnected. The Sunny Centrals continue to operate individually until the failure is
rectified.
If a failure is present for more than 60 minutes, Team mode can be resumed. For Team mode to be
possible while a failure is present at a Sunny Central, the following conditions must be fulfilled:
• The communication between the two Sunny Centrals must be functioning.
• The DC contactor must be functioning.
• The start-up key switch must be set to the "Start" position.
• None of the following failures must be present:
– Failure 201: Ground Fault 2 or plant temp. too high
– Failure 206: Emergency shutdown activated
If these conditions are fulfilled, the Sunny Central at which no failure is present takes over the output
of both solar generators.
