Danger to life from electric shock due to high voltages
High voltages are present on the AC power cables and on the control cables. Touching live components can
result in death or serious injury due to electric shock.
• Disconnect the Sunny Island from voltage sources (see Section 9, page 45).
4. If the connections
AC1
and
AC2
are bridged, remove the bridge.
5. If a mobile generator is used, disconnect the generator from connection
AC1
.
6. If the system is a single-cluster system (single-phase or three-phase) or a multicluster system, restore the system-
specific connection (see quick reference guide of the used system).
7. Close the Sunny Island (see commissioning section in the Sunny Island inverter installation manual).
Starting the Off-Grid System
1. Connect or close all circuit breakers and fuse-switch-disconnectors.
2. Start the system (see Section 4.2, page 20).
10.8
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
<Init System>
, press and hold the button on the Sunny Remote Control.
☑ 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.
