Installation Manual
Cause and corrective measure
It is possible that the SMA device is not correctly con-
nected to the router or is not supplied with voltage.
Corrective measures:
• Ensure that the SMA device is correctly connected to
the router and is supplied with voltage (see SMA
device documentation).
The SMA device is already registered in Sunny Portal via
Webconnect.
Corrective measures:
• Delete the SMA device from the Webconnect system
or deactivate the data reception of the device in the
Webconnect system.
For Speedwire devices with integrated BLUETOOTH inter-
face:
It is possible that the communication via BLUETOOTH is
not deactivated.
Corrective measures:
• Set NetID 0 on the Speedwire device with
BLUETOOTH interface. This deactivates
communication via BLUETOOTH.
The SMA device is not located in the same local network
as the Sunny Home Manager.
Corrective measures:
• Connect the SMA device to the same router/
network switch as the Sunny Home Manager.
The network cable that connects the SMA device to the
router/network switch is not suitable for 100 MBit/s.
Corrective measures:
• Use a network cable suitable for Speedwire (for
network cable requirements, see the Speedwire
device documentation).
