Problem Cause and corrective measures
The Sunny Home Manager
detects none or not all of the
new SMA devices that are
connected via Speedwire. It is possible that the SMA device is not correctly connected to the
router or is not supplied with voltage.
Corrective measures:
• Ensure that the SMA device is correctly connected to the
router and supplied with voltage (see manual of the SMA
device).
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 interface:
It is possible that the communication via BLUETOOTH is not
deactivated.
• 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 manual of the Speedwire device).
DHCP is not activated in your router.
Corrective measures:
• Activate DHCP in the router.
• If your router does not support DHCP, configure the static
network settings on the Speedwire device using SMA
Connection Assist. You can obtain the SMA Connection
Assist software free of charge from the download area at
www.SMA-Solar.com.
