14.3 Operating States of Sunny Team
During normal daily operation, the Sunny Team goes through four phases. These 4 phases are
described below.
Phase Explanation
In the morning Vpv > VpvStart - 50 V: The DC contactor closes. The system
changes to team mode. The Sunny Centrals are factory preset for
alternating grid feed. The team manager feeds into the grid on
even-numbered days and the team member on odd-numbered
days. The Sunny Central designated for grid feed goes into
operation as soon as the start requirements are fulfilled, and feeds
the entire system power into the public grid.
80 % of AC nominal power
exceeded AC nominal power > P-Next Team (default setting 80 %): The DC
contactor opens. The two Sunny Centrals now work separately.
Both Sunny Centrals are in operation, converting the power of their
PV generator and feeding it into the public grid.
Power drops below 20 % of
"Pac smoothed". Pac smoothed < P-Prev Team (default setting 20 %): the DC
contactor closes. The system switches to Team mode. The team
manager determines which Sunny Central is to convert the energy
and feed into the grid. The grid-feeding Sunny Central feeds the
entire system power into the public grid.
In the evening Open-circuit voltage of the grid-feeding Sunny Central for
30 minutes < Vpvmin - 100 V: the DC contactor opens. The Sunny
Centrals are disconnected from each other. This state is maintained
until the following morning.
