14 Sunny Team (optional)
You have the option of operating two Sunny Centrals with identical nominal power as a Sunny Team.
Sunny Team is a circuit with a DC contactor which connects the two Sunny Centrals electrically. In
case of low solar radiation the DC contactor closes and the two Sunny Centrals (manager and team
member) are connected in parallel on the DC side. One Sunny Central converts the power of the
entire system and feeds it into the public grid. The team manager and the team member take turns to
feed into the grid. The team manager feeds into the grid on even-numbered days and the team
member on odd-numbered days. While one Sunny Central is feeding into the grid, the other changes
to "Wait" mode.
Requirements for team operation:
• 2 Sunny Centrals with the same nominal power
• 2 Sunny Centrals are equipped with Sunny Team
• Same number of PV modules per string
• PV modules of the same type
• PV modules with identical vertical and horizontal arrangement
The connection of the team cabling and the installation of team systems is described in the Sunny
Central installation guide.
Manager device
The manager device is responsible for the operational control of the team and insulation monitoring
of the entire system. In cases of low solar radiation, the manager device specifies which team member
should feed the entire system power into the grid, and which team member should switch to "Wait"
mode.
Team device (team member)
In team operation, the insulation monitoring system of the team member is in “Standby” mode. Two
insulation monitoring systems cannot operate simultaneously, as the two devices would interfere with
each other.
14.1 Identification of Manager Device and Team Device
The type label includes a version key which specifies whether the Sunny Central is the manager or the
team device. You can identify the Sunny Central's team function by comparing the version key on the
type label with the explanation of the version key in the wiring diagram.
14.2 Display of Team Mode on the Sunny Central
In team mode, the indicator light for team operation is lit on both Sunny Centrals. The DC contactor
is closed, one Sunny Central feeds the entire system power into the public grid.
