Communication between Sunny Multigate and Other Communication Products
Figure 7: Example of a PV system with micro inverters and Sunny Multigate with communication via Speedwire/
Webconnect
Communication between the Sunny Multigate and other SMA communication products (e.g.
Sunny Explorer, Sunny Portal) takes place via Speedwire/Webconnect. Speedwire is a type of
communication based on Ethernet. You can connect the Sunny Multigate to your network via
Speedwire. Webconnect enables data exchange between Sunny Multigate and Sunny Portal. In
order to establish a connection to Sunny Portal, the Sunny Multigate must be connected to a router
or modem with Internet connection and be integrated into the local network. To enable data
exchange between Sunny Multigate and Sunny Portal, you must register the PV system in
Sunny Portal (see Section 8.3 "Registering the Sunny Multigate in Sunny Portal", page 45). If you
do not want to use the Webconnect function, you can deactivate it in Sunny Explorer (see
Section 8.7 "Deactivating the Webconnect Function", page 47).
