Why does the error F117 (AC voltage too high) also occur when the <strong>Sun</strong>ny Island<br />
is started?<br />
• A permanent short-circuit exists in the stand-alone grid system. Check the AC output connections<br />
of the stand-alone grid system (see section 6.3 ”AC Connection” (page 36)).<br />
• The loads connected to the stand-alone grid system are too heavy. The power/electrical energy<br />
of the <strong>Sun</strong>ny Island is not sufficient to supply the loads. Switch off some of the loads and restart<br />
the <strong>Sun</strong>ny Island.<br />
What do I do when a battery cell can no longer be used?<br />
• Remove the unusable cell from your battery bank. Start the <strong>Sun</strong>ny Island and change the battery<br />
voltage in the QCG under "New Battery".<br />
What can I do when the QCG does not run?<br />
• Switch off the <strong>Sun</strong>ny Island (see section 9.3 ”Switching Off” (page 64)) and restart it<br />
(see section 9.1 ”Switching On” (page 62)).<br />
What can I do when "MMC operation failed" appears on the display?<br />
• You wanted to perform an action using the SD card, but it failed (see section 10.9 ”Display of<br />
Warnings and Failures” (page 82)). Check the card (on your PC/laptop) and use a new<br />
SD card, if necessary.<br />
Why does my <strong>Sun</strong>ny Island stay on even though I switched the DC circuit breaker<br />
to Off?<br />
• Your <strong>Sun</strong>ny Island may be powered by the AC side. Switch off all AC consumers and disconnect<br />
them from the <strong>Sun</strong>ny Island (see section 9.4 ”Disconnecting the Device from Voltage Sources”<br />
(page 64)).<br />
Why is my battery discharging even though the generator is running?<br />
• The power produced by the generator does not reach the <strong>Sun</strong>ny Island. Check the voltage and<br />
frequency values. The fuses on the generator may have been tripped.<br />
• The consumer power exceeds the generator power "234.03 GnCurNom".<br />
– Check error messages Find the cause.<br />
Why is the deactivation defined by the SOC in case of a full or equalization<br />
charge and generator start in the second time zone?<br />
• The equalization charge has a higher priority than silent time.<br />
Why is the SOC not at 100 %, even after completion of a full charge?<br />
• Set a longer absorption period.<br />
How is it possible to ensure that the maximum battery charging current is<br />
correctly calculated after a reinstallation of the battery current sensor?<br />
• Recalibrate the battery current sensor using the "225.04 BatCurAutoCal" parameter with the<br />
setting "Start".<br />
