Corrective measures
• Reset the off-grid system. For this,
disconnect all loads, AC sources,
generator and DC sources. Open
the load-break switch of the
BatFuse. Wait ten minutes and
restart the off-grid system. Wait until
all AC sources are feeding into the
stand-alone grid and all loads are
connected before connecting the
generator.
• Contact the Service (see Section 16
"Contact", page 161).
• Check whether the value of the
parameter 250.23 Box matches
the Multicluster-Box. If the value
does not match, restart the QCG
(see the Sunny Island inverter
installation manual).
• Contact the Service (see Section 16
"Contact", page 161).
• Acknowledge the error (see
Section 10.3, page 47).
• Contact the Service (see Section 16
"Contact", page 161).
