9.7 Changing Slave Addresses in a Cluster
If you want to change slave addresses (e.g. after replacing a Sunny Island) you can assign the slaves a new address
using the Quick Configuration Guide (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 "Off-Grid Systems" for configuring single-cluster operation or multicluster operation).
You can change the slave addresses in two ways:
• Change the slave addresses with a Sunny Remote Control.
• Change the slave addresses without Sunny Remote Control.
Changing Slave Addresses with a Sunny Remote Control
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. Turn on the master and then press and hold the button on the Sunny Remote Control.
☑ An acoustic signal sounds three times and the QCG starts.
3. Select the NewClstCfg menu on the Sunny Remote Control and confirm with Y.
4. For a single-phase system, set 1Phs and press the button.
5. 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 flashes 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 flashes 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.
