5.2 Preparing for Speedwire Communication
If the Sunny Home Manager is to communicate with other SMA devices via Speedwire,
the Sunny Home Manager and the Speedwire devices must be in the same local network.
Perform the following preparatory steps.
Requirements:
☐ A NetID other than NetID 1 must be set on the Sunny Home Manager (see Section 5.1.2
"Configuring the NetID on the Sunny Home Manager", page 29). This enables the
Sunny Home Manager to connect to several devices simultaneously via Speedwire or
BLUETOOTH.
☐ DHCP must be activated on the router (see router manual). If your router does not support
DHCP, you can configure the static network settings on the Speedwire device using
SMA Connection Assist* .
☐ All UDP ports > 1024 on the router or modem must be open for outgoing connections. If there
is a firewall installed on the router or modem, you might have to adjust the firewall rules.
☐ It must be possible for the outgoing router or modem connections to reach all Internet
destinations (target IP, target port). If there is a firewall installed on the router or modem,
you might have to adjust the firewall rules.
☐ On a router or modem with NAT (Network Address Translation), no port forwarding should be
set up. This will help prevent potential communication problems.
☐ There must be no packet filtering or manipulation for SIP packets installed on the router or
modem.
Procedure
2. Connect the Speedwire devices to the router/network switch (see Speedwire device manual).
Make sure that the distance to the mounting location of the Sunny Home Manager is not too
great, as the Sunny Home Manager must later be connected to the same router/network switch.
Inverters with Webconnect function
If an inverter is already registered in Sunny Portal with the Webconnect function, the inverter
cannot be added to the Sunny Home Manager system.
• Delete the inverter with Webconnect function from the Webconnect system or deactivate
data reception for the inverter in the Webconnect system.
* You can obtain the SMA Connection Assist software free of charge from the download area at www.SMA-Solar.com.

Deactivating the BLUETOOTH communication of the inverters
If an inverter communicates with the Sunny Home Manager simultaneously via
Speedwire and BLUETOOTH, data recording errors will result.
• For inverters with BLUETOOTH interface, set NetID 0 (see inverter or Bluetooth
Piggy-Back manual). This deactivates communication via BLUETOOTH.
