Description of the Sunny Central SMA Solar Technology AG
12 SC-BEN092751 User Manual
3.2.2 Light Indicators
Three light indicators are situated on the front of the Sunny Central. If an error occurs, the type of
disturbance is shown by these light indicators.
3.2.3 Start-up Key Switch
The start-up key switch activates or deactivates the Sunny Central. When this switch is turned to the
"Start" position, the Sunny Central changes from "Stop" mode to "Wait" mode. If there is sufficient
radiation, the Sunny Central changes to the "Startup" mode, and subsequently begins grid feeding. If
the radiation, and thus the input voltage, is too low, the Sunny Central remains in "Wait" mode.
If the start-up key switch is turned to the "Stop" position, the DC switch is deactivated automatically by
a motor drive.
3.2.4 Emergency Shut-off
The emergency shut-off switch immediately disconnects the Sunny Central from the grid, and from the
solar generator, placing the Sunny Central in a safe condition.
When the emergency shut-off switch is pressed, it locks in the "Off" position. The emergency shut-off
switch can only be unlocked using its key. It is also necessary to reset the emergency shut-off operation
with the Sunny Central Control or with Sunny Data Control.
The Sunny Central 100 indoor and the Sunny Central 100 outdoor have no emergency shut-off
switch. You have the option of installing an external emergency shut-off switch at the Sunny Central.
You can also install an external emergency shut-off switch at the other Sunny Centrals, or deactivate
several Sunny Centrals with a shared emergency shut-off switch.
• Yellow: The Sunny Central is in "Alert" mode. The Sunny Central does not switch itself off.
Once the error is no longer present, the error message is reset automatically. Check
the system.
• White: The Sunny Centrals are operating in Team mode. The Team contactor is activated.
• Red: The Sunny Central is in "Failure" mode. If the Sunny Central has detected a failure,
it shuts down. Once the fault has been removed and confirmed, it resumes
operation. For more information, see section 9.1.2 "Types of Failures and
Warnings" (page46).
NOTICE!
Improper use of the emergency shut-off switch causes damage to the Sunny
Central!
The Sunny Central's components are subjected to considerable stress if the emergency shut-
off switch is used under load. This can irreparably damage individual components.
• Only use the emergency shut-off switch in an emergency.
• To switch off the Sunny Central, use the start-up key switch.
