Charger charge controller
installation manual).
• 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 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
