4.4 Communication
Communication between inverter and Sunny Multigate
The inverters are connected to the Multigate XT, and consequently the Sunny Multigate,
via the AC cable. The communication and data transmission between the Sunny
Multigate and the inverters takes place via a Powerline interface.
Communication between Sunny Multigate and other
communication products
Communication between the Sunny Multigate and other SMA communication products (e.g.
Sunny Portal, Sunny Explorer) takes place via Speedwire. Speedwire is an Ethernet-based
type of communication. You can connect the Sunny Multigate to your network via Speedwire.
The Webconnect function enables data exchange between Sunny Multigate and Sunny Portal.
Sunny Portal is an Internet portal for the monitoring of plants as well as for the visualization and
presentation of plant data. In order to establish a connection to Sunny Portal, the Sunny Multigate
must be connected to a router with Internet connection and be integrated into your network. To
enable data exchange between Sunny Multigate and Sunny Portal, you must register the PV
plant in Sunny Portal (see user manual of Webconnect plants in Sunny Portal at www.SMA-Solar.
com). For this purpose, you will need the access data, identification key (PIC) and registration ID
(RID) which are located on the type label of the Sunny Multigate and the inside of the door of the
Multigate XT. Once you have registered the Sunny Multigate, you will be able to monitor your PV
plant in Sunny Portal.
