SYSTEM
ERROR
Ground fault alarm.
An audible alarm will be heard, indicating the Ground Fault has continued
for more than one minute. The fault is confirmed by notifications on email
and the Redback portal.
Contact your installer as soon as possible.
Other error
(no audible alarm).
Wait 10 minutes. System errors may be caused by temporary external
factors, such as grid power quality, and may resolve without intervention.
If the error does not resolve within 10 minutes, restart the inverter (9.4).
If the error does not resolve following a restart:
• Move the Bypass switch to the UP position- this maintains continuous
grid supply to the backup circuit. Note: backup function will be halted.
• Contact your installer as soon as possible.
