: Last
communication with the Sun-
ny Island Charger 4 was more
than 24 hours ago.
• Ensure that undamaged CAT5e
cables are used for communication
and that the cables are plugged in
correctly.
• Ensure that the configuration of the
Sunny Island Charger charge
controller with the DIP switches is
correct.
• Ensure that the communication
interfaces are correctly inserted in
the Sunny Island.

• Ensure that the control and
measuring cable between the
Multicluster-Box and the
corresponding Sunny Island of the
main cluster is correctly inserted.
When doing so, observe the correct
sequence of the Multicluster-Box
connections to the Sunny Island
inverters (see the Sunny Island
inverter installation manual and the
Multicluster-Box documentation).
