Operating Manual
10.2 Acknowledging a Generator Error
Requirement:
☐ The Sunny Remote Control must be in standard mode or user mode.
1. Rectify the cause for the disconnection of the generator from the stand-alone grid
(see the technical description of the off-grid inverter for causes of errors and disturbances).
2. Select the
Generator
display page on the Sunny Remote Control and push the button
(see Section 4.3.5 "Operating and Configuring the Off-Grid Inverter", page 30).
3. Set the
Error
parameter to
Ackn.
10.3 Acknowledging Level 3 and 4 Errors
If a disturbance or failure has occurred, the off-grid inverter switches to standby mode.
1. Rectify the cause (see the technical description of the off-grid inverter for the causes of errors
and disturbances).
2. Push the button on the Sunny Remote Control. This acknowledges the error.
3. Start the off-grid system (see Section 5.2).
10.4 Changing Slave Addresses in a Cluster
If you want to change slave addresses (e.g. after replacing an off-grid 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 installation manual of the off-grid inverter on the configuration of
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 a Sunny Remote Control.
Changing Slave Addresses with a Sunny Remote Control
Requirements:
☐ The off-grid inverters must be switched off.
☐ A Sunny Remote Control is connected to the master only.
1. Switch the slave on.
2. Turn on the master and then press and hold the button on the Sunny Remote Control.
☑ A signal sounds three times and the QCG starts.
3. Select the
NewClstCfg
menu and confirm with
Y
.
4. For a one-phase system, set
1Phs
and press the button.
5. For a three-phase system, set
3Phs
and press the button.
