Follow these steps in order. Use the detailed sections for model-specific settings and the complete object reference.
1 Installation vorbereiten
Have the gateway, KNX bus connection, 12-30 VDC auxiliary supply, network connection, ETS application and inverter configuration access ready. Check compatibility and firmware in Sections 3 and 10.
2 Gateway anschließen und versorgen
Connect KNX at the top. Connect auxiliary power and RJ45 Ethernet at the bottom. Connect the equipment to the same local network. The green Network LED confirms the Ethernet link; see Section 3.
3 Wechselrichterverbindung konfigurieren
Enable Modbus TCP or configure the required inverter connection using Section 4. Confirm the inverter address, port and Unit ID.
4 Gateway-Netzwerk und Modbus-Verbindung einstellen
Open 192.168.1.51 from a laptop on a compatible network and assign an appropriate fixed gateway IP address. Set Mode to Connect, Server IP to the inverter address, Server Port to 1502 and Unit ID to 71.
5 KNX-Gerät in ETS konfigurieren
Assign a free physical address. Set Inverter model to 5. Set the AC network, applicable PV circuits, refresh rate and available equipment. Set Device Options to 9 for default register addressing. See Sections 5 and 6.
6 Gruppenadressen verknüpfen und herunterladen
Assign group addresses to the required objects. Press P when ETS requires programming mode and perform a full application download for initial commissioning. See Section 5.
7 Daten validieren und Logik aktivieren
Check the Connected LED and Module status (GO 1 = 0). Read firmware (GO 2), wait for the polling interval and compare live values with the inverter. Check power directions and optional equipment before enabling logic. See Section 7.
Die Inbetriebnahme ist abgeschlossen, wenn
The network and inverter links are established, the ETS download succeeds, and the required group objects return plausible values for the installed equipment.
