PROTOCOL
> “Speedwire” is the name of wired, Ethernet
based communication using IP protocol
and SMA Data 2+
> Connect via standard RJ45 network port
> Enables data transmission within a local PV
network between inverters & SMA
communication devices.
> No communication to the Internet

20. WEBCONNECT- DIRECT DATA EXCHANGE TO
SUNNY PORTAL
> Uses “Speedwire“ high speed data transfer
for local network communication
> Enables direct data transmission
between inverters and Sunny
Portal/Sunny Places without additional
communication devices
> Generally not advised for commercial
plants with complicated networks on-site.
Alternative is to use 3G/4G modem if
network is complicated
> Register up to 4 inverters per plant in
Sunny Portal (separate plant tab for
inverters 5th to 8th)
> Can be separate module or integrated
RJ45 ports
> Building blocks for a communication
network

21. WEBCONNECT APPLICATIONS IN COMMERCIAL
SYSTEMS WITHOUT SUNNY PORTAL ACCESS
> Webconnect also has Modbus
communication feature- SMA & Sunspec
Allows for direct communication between
Building Management Systems (BMS) &
Inverters.
> There is no limit on SMA-side for this
type of communication; limit is the network
restriction of IP assignment
- For networks with limited IP
addresses, Cluster Controller can be used
to act as gateway to multiple inverters, so
only 1x IP Address is used instead of x
times the inverters.
