9.5 Frequently Asked Questions (FAQ)
9.5.1 Questions Regarding the Sunny Island
The Sunny Island does not switch off even though you have opened the load-break switch of the
BatFuse?
The Sunny Island may still be supplied from the AC side.
•
Switch off all AC sources and disconnect them from the Sunny Island.
The Sunny Island does not switch to energy saving mode?
Another function might have a higher priority than energy saving mode, e.g., equalization charge or full charge.
After automatic disconnection in battery protection mode, the Sunny Island can no longer be started?
•
Only charge the battery when the Sunny Island cannot be switched on (see Section 9.6 "Charging the Battery
After Automatic Shutdown in Off-Grid Systems", page 72).
• Switch off all loads.
• If there is a generator in the system, start the generator manually. When doing so, observe the warm-up time of
the generator. Five minutes without charge current can result in disconnection of the Sunny Island inverter.
• If sufficient power is available from the generator or the AC sources in the stand-alone grid, e.g., sufficient solar
irradiation for PV inverters, switch the Sunny Island on. AC sources in the stand-alone grid can only start feeding
in electric current once the Sunny Island has been started and is in operation.
9.5.2 Questions Regarding the Sunny Remote Control
The display of the Sunny Remote Control is dark and nothing is displayed?
The Sunny Island might not be switched on.
• Switch the Sunny Island on (see Section 4.1, page 18).
✖ The Sunny Island does not switch on?
•
Ensure that the fuse in the BatFuse is not defective.
The Sunny Remote Control might not be connected to the Sunny Island.
•
Ensure that the Sunny Remote Control is connected to the Sunny Island.
The RJ45 data cable may be damaged.
•
Replace the RJ45 data cable between the Sunny Remote Control and the Sunny Island.
Parameters cannot be changed?
The parameter might only be displayed in expert mode.
• Switch to expert mode on the Sunny Remote Control (see Section 5.4.1, page 29).
The parameter might only be changeable in standby mode or in the QCG.
• Observe the messages in the display (see Section 5.4.6 "Setting the Parameters", page 31).
The parameter may be hidden as it is not required in the configuration set for the system.
• Ensure that the configuration does not deactivate any functions which are required.
