<strong>SMA</strong> <strong>Solar</strong> <strong>Technology</strong> <strong>AG</strong> Settings<br />
10.2.1 Setting <strong>SMA</strong>-COM<br />
If the devices of your PV plant are to communicate with the Sunny WebBox via <strong>SMA</strong>-COM, you must<br />
configure this communication method.<br />
Data transmission protocols<br />
<strong>SMA</strong> inverters use proprietary protocols for data transmission.<br />
The inverters have been using the data protocol "<strong>SMA</strong>-NET" since the year 2000. Older<br />
inverters use the data protocol "<strong>SUNNY</strong>-NET". The <strong>SMA</strong>-NET and <strong>SUNNY</strong>-NET data<br />
protocols cannot be used together in a PV plant.<br />
1. Select "Plant > Settings" in the user interface.<br />
2. Select the data protocol of the devices in the "Transfer protocol" field. The following selections<br />
are possible for the listed inverter types:<br />
"<strong>SMA</strong>-NET" • Sunny Boys of type SWR, version BFR 8.22 or above<br />
• All type SB Sunny Boys<br />
• All Sunny Mini Central devices<br />
• All Sunny Island devices<br />
• All Sunny Central devices<br />
• Sunny SensorBox<br />
"<strong>SUNNY</strong>-NET" • Sunny Boys of type SWR prior to version BFR 8.22<br />
Default Baud rate<br />
If not all devices operate using the typical <strong>SMA</strong> baud rate setting of 1200 baud,<br />
communication problems may occur. Change the baud rate to 1200 baud if necessary.<br />
Only change the baud rate from 1200 baud when absolutely necessary.<br />
3. Select the inverter baud rate in the "Baud rate" field (not if "Ethernet" is set as the communication<br />
method).<br />
"1200" All <strong>SMA</strong> devices<br />
"9600" Reserved for future developments<br />
"19200" Reserved for future developments<br />
4. Select [Save].<br />
☑ The PV plant communication has been set.<br />
