Installation Manual
6.3.2 Creating a Small-Scale PV System in Sunny Explorer
Requirements:
☐ The system must be commissioned (see Section 6.2, page 20).
☐ Sunny Explorer must be installed on the computer (see Section 2.4 "Supported Products",
Procedure:
1. Connect the computer to the system router with a network cable.
2. If you have used SMA Connection Assist for the static network configuration, ensure that
SMA Connection Assist has ended.
3. Start Sunny Explorer and create a Speedwire system for the small-scale PV system in
Sunny Explorer (see Sunny Explorer help).
6.4 Configuring the Modbus Function
If you wish to access SMA inverters with Modbus interface, make sure that the Modbus connection
of the devices has been configured correctly. In devices with Modbus, the same port must be set up
for the Modbus communication. The Modbus function has been deactivated by default in the
Speedwire/Webconnect data module and port 502 has been set for the Modbus servers TCP and
UDP. For information on using the Modbus interface, see the Technical Descriptions "SMA Modbus
®
Interface" or "SunSpec
®
Modbus
®
Interface" at www.SMA-Solar.com.
For information on which of the supported SMA inverters (see Section 2.4) support the Modbus
interface of the Speedwire/Webconnect data module, see the datasheet "SMA_Modbus-DB-en.xlsx"
at www.SMA-Solar.com.
Procedure:
• If necessary, adjust the preset ports in the Speedwire/Webconnect data module for the
Modbus communication (see the Technical Descriptions "SMA Modbus
®
Interface" or
"SunSpec
®
Modbus
®
Interface" at www.SMA-Solar.com).
