9.7 Changing Slave Addresses in a Cluster
If you want to change slave addresses (e.g., after replacing a Sunny Island inverter), you can assign the slaves a new
address using the QCG. Only the address is changed, all other configurations remain as they were, e.g., assignment of
the clusters in a multicluster system. When replacing a master, you must reconfigure the cluster (see the quick reference
guide for the relevant system for configuring single-cluster operation or multicluster operation).
Requirements:
☐ All Sunny Island inverters must be switched off.
☐ A Sunny Remote Control is connected to the master only.
Procedure
1. Switch the slave on.
2. Switch the master on.
3. When the Sunny Remote Control shows
☑ An acoustic signal sounds three times and the QCG starts.
4. Select the NewClstCfg menu on the Sunny Remote Control and confirm with Y.
5. Select number of line conductors in the system:
• For a single-phase system, set 1Phs and press the button.
• For a three-phase system, set 3Phs and press the button.
6. Confirm the question Setup new cluster ? with Y.
7. Wait until the inverter LED of slave 1 is flashing and the Sunny Remote Control shows the message To identify
Slave1 press Tss on the Slv.
8. Press the start-stop button on slave 1.
☑ The QCG configures slave 1.
9. To configure slave 2, wait until the inverter LED of slave 2 is flashing and the Sunny Remote Control shows the
message To identify Slave2 press Tss on the Slv.
10. Press the start-stop button on slave 2.
☑ An acoustic signal sounds and the QCG configures slave 2.
11. Press the button on the Sunny Remote Control. This closes the QCG.
☑ The Sunny Remote Control switches from display mode to standard mode.
