10 Troubleshooting
Corrective measures
• 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 battery is correctly
connected to the DC connection of
the Sunny Island Charger charge
controller.
• Disconnect the PV array from the
Sunny Island Charger and restart
the system. This will ensure that the
PV array is not short-circuited.
