Inverter Status LEDs

Your Redback inverter is equipped with an LED array to indicate
system status and aid diagnosis.
The table below lists LED indications, probable cause, and
rectification steps you can try yourself. Refer to page 9 to identify

ON: PV is detected.
OFF, and batteries are installed: Turn BATTERY
SYSTEM DC isolator ON (up).
OK. No action required. Both arrays are active.
OK. No action required.
No action required- this is normal operation. When (Instantaneous PV +
Battery power) exceeds House Demand, the shortfall is met by the grid.
If Batteries are not fulfilling house demand as expected, contact your
installer.
No action required- this is normal operation: The house demand is
being fulfilled by the battery and or PV.
No action required: this is normal operation. Power is exported to the
grid when PV exceeds (Battery charging + House demand). Contact your
installer if this is unexpected behaviour e.g. exporting while the battery
is not full and not charging.
OFF: Turn grid isolators ON.
ON: Contact your installer or Redback.
