Preparing for Speedwire Communication
If the Sunny Home Manager is to communicate with other SMA devices via SMA Speedwire (Ethernet), the Sunny Home Manager and the Speedwire devices must be in the same local network. Only one system with Sunny Home Manager may be installed in the local network. If there are several systems with SMA devices, these must be separated from each other in the network, for example by using sub-networks.
Inverter 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 in Sunny Portal.
- In order to be able to add the inverter to the Sunny Home Manager system in Sunny Portal, delete the inverter with Webconnect function from the Webconnect system in Sunny Portal or deactivate data reception for the inverter in the Webconnect system in Sunny Portal.
Requirements:
DHCP must be active on the router (see router documentation).
All UDP ports > 1024 on the router must be open for outgoing connections. If there is a firewall installed on the router, you might have to adjust the firewall settings.
It must be possible for the outgoing router connections to reach all Internet destinations (target IP, target port). If there is a firewall installed on the router, you might have to adjust the firewall settings.
On the router with Network Address Translation), no port forwarding must be entered. Potential communication problems can thus be prevented.
The routers and network switches with router function must forward the Multicast telegrams (telegrams with destination address 239.0.0.0 to 239.255.255.255) required for the Speedwire connection to all nodes of the Speedwire network.
All network components used must support the IGMP protocol, minimum version 3 (IGMPv3) (see network component documentation).
Procedure:
- Connect the Speedwire devices to the router (see Speedwire device documentation).
