Configuring The Energy Meter; Configuring The Modbus Function - SMA SUNNY ISLAND 4.4M Operating Manual

SMA Solar Technology AG
Requirement:
☐ If the WLAN function was previously switched off completely, the inverter must be connected to a computer or
router via Ethernet.
Procedure:
• To switch on the WLAN direct connection, in the parameter group PV system communication > WLAN, select
the parameter Soft-access-point is turned on and set this to Yes.
• To switch on the WLAN connection in the local network, in the parameter group System communication >
WLAN, select the parameter WLAN is turned on and set this to Yes.

Configuring the Energy Meter

You can add an energy meter to your PV system or replace an existing energy meter.
The basic procedure for changing operating parameters is explained in another section (see Section 9.2 "Changing
Operating Parameters", page 119).
Removing a detected energy meter from the PV system
If only one energy meter is detected by the inverter, this will be added to the PV system automatically. Removal
via the menu Device configuration is not possible in this case. To remove the energy meter from the PV system,
proceed as follows:
• In the parameter group System communication > Measured values > Meter on Speedwire, set the
parameter Serial number to any number (e.g. 1). In this way, instead of the energy meter detected, the PV
system will add a fictitious energy meter to which the inverter cannot establish communication.
Procedure:
1. Activate the user interface (see Section 8.1, page 110).
2. Log in as Installer.
3. Start the installation assistant (see Section 9.1, page 118).
4. In the context menu, select [Starting the installation assistant].
5. Select [Save and next] until you get to the step Meter configuration.
6. Add or replace the desired energy meter.
9.7 Configuring the Modbus Function
The Modbus interface is deactivated by default and the communication ports 502 set.
In order to access SMA inverters with SMA Modbus
interface, the communication ports of the IP protocol can be changed. For information on commissioning and
configuration of the Modbus interface, see the technical information "SMA Modbus® Interface" at www.SMA-
Solar.com.
For information on which Modbus registers are supported, see the technical information "SMA Modbus® Interface" at
