6.3 Managing Small-Scale PV Systems with Sunny Explorer

6.3.1 Functions and Parameter Settings in Sunny Explorer

The following functions for small-scale PV system management are available in Sunny Explorer:
• Overview of the PV system status
• Graphic display of key PV system data, device data and the respective energy values
• Parameterization of individual devices or entire device classes
• Simple diagnostics thanks to display of faults and events
• Data export of inverter energy values and events in CSV format
• Device updates
You can change the following parameters with Sunny Explorer:
• Device name of the inverter
• Automatic IP configuration On/Off
• DNS-IP, gateway IP, IP address, subnet mask
• Webconnect function On/Off
• Modbus function On/Off

6.3.2 Creating a Small-Scale PV System in Sunny Explorer

Requirements:
☐ The small-scale PV system must be commissioned (see Section 6.2, page 22).
☐ Sunny Explorer must be installed on the computer (see Section 2.4 "Supported Products",
page 11).
Procedure:
1. Connect the computer to the PV system router with a network cable.
2. If you have used the SMA Connection Assist for static network configuration, ensure that the
SMA Connection Assist has terminated.
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 each of the devices with Modbus, the same port must
be configured for Modbus communication. The Modbus function is deactivated by default in the
Speedwire/Webconnect data module, and port 502 is configured for the Modbus servers TCP and
UDP. Information on how to use the Modbus interface can be found in the technical description
®
"SMA Modbus Interface" or "SunSpec
For information on which of the supported SMA inverters (see Section 2.4) support the Modbus
interface of the Speedwire/Webconnect data module, refer to the datasheet
