  • SUNNY TRIPOWER HYBRID X 5 / 6 / 8 / 10 / 12 / 15 / 20 / 25 / 30

    • If it is used exclusively as a PV inverter.
The latest firmware should always be installed.

2. Configuration via the SMA Web Interface

Before integrating the inverter into FEMS, you should make sure that all necessary preparations have been made.

This includes configuring the inverter via the web interface.

Before configuring the PV inverter, make sure that it has been installed properly. Use the manufacturer’s installation instructions for this.

To integrate the device into FEMS, please configure it via the web interface. You can access the web interface by entering the inverter’s IP address in your browser. We recommend setting the IP address assignment to "Automatic" during the device’s commissioning.

To be able to access the web interface, your PC/notebook/smartphone must be in the same network as the inverter.

2.1. IP address

The connection between FEMS and the PV inverter is always established via the customer network. For this purpose, the IP address of the PV inverter is stored statically in FEMS. It is therefore necessary that the IP address of the PV inverter never changes.

  • Variant 1: Configure the SMA PV inverter according to the instructions so that it is assigned a static IP address.

  • Option 2: Configure the inverter according to the instructions so that it is assigned a dynamic/automatic IP address. Additionally, configure the DHCP server in the customer’s network (e. g., AVM FritzBox ) so that the inverter is always assigned the same IP address.

2.2. Ping test

To test the correct configuration of the IP address, we recommend pinging the inverter in the local customer network.

In the example below, the IP address 192.168.188.40 was set for the inverter in the configuration.

If the inverter cannot be reached via ping, check the settings under IP address.

2.3. Modbus/TCP

Make the following settings according to the instructions:

  1. Enable the TCP server.

  2. Set the port to 502.

  3. Unit ID — Enter the following value: 3.

3. Integrating the PV inverter into FEMS

After you have configured the settings on the PV inverter, you can integrate it into FEMS.

Prepare to install the FEMS App by following these instructions:

After entering the key, you will see the following screen:

FEMS — Installation — PV-Wechselrichter

Some of the input fields are pre-filled.

The alias is the name under which the PV inverter is displayed in FEMS. You can choose any name you like, but it should be meaningful.

Required fields are marked with an *.

  1. Check the IP address. You can find this either in the web interface of the respective PV inverter or in the list of devices registered on the router (e. g., Fritz!Box). If necessary, adjust the IP address so that they match.

  2. The port should be set to 502 in accordance with the standard.

  3. For the Modbus Unit ID, if a value has already been set in the PV inverter’s web interface, 123 must be added to that value. Enter this result as the Modbus Unit ID in FEMS.

  4. Finally, specify which phase(s) is/are connected to the PV inverter.

Complete the installation by selecting INSTALL APP.

The integration of the PV inverter into FEMS is now complete.

You will then find the integrated PV inverter as a submenu item under Production in the FENECON App.
