Follow these steps in order. Use the detailed sections for model-specific settings and the complete object reference.
1 Préparer l’installation
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 Raccorder et alimenter la passerelle
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 Configurer la connexion de l’onduleur
Enable Modbus TCP or configure the required inverter connection using Section 4. Confirm the inverter address, port and Unit ID.
4 Configurer le réseau de la passerelle et la liaison Modbus
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 Configurer l’appareil KNX dans ETS
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 Lier les adresses de groupe et télécharger
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 Valider les données et activer la logique
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.
La mise en service est terminée lorsque
The network and inverter links are established, the ETS download succeeds, and the required group objects return plausible values for the installed equipment.
