Troubleshooting

Most frequent symptoms

SYMPTOM
No LEDs are illuminated
No solar generation
Lower solar generation
than expected
Inverter overheating
Note: your inverter is
passively cooled and relies on
a temperature difference
between the inverter casing
and ambient air. Air flow
obstructions, or anything that
reduces the temperature
differential also reduces the
inverter's self-cooling
efficiency.
Inverter operating

Red Inverter Status LED
Purple Flashing EMS
Network LED
PROBABLE CAUSE
Local blackout
No Grid Power to

No Solar Generation
No Grid Power
PV turned is OFF
Insufficient sunlight
PV Shading
Dirty PV Panels
Inverter overheating
Insufficient cooling
Very hot day
Ambient temperature

External heat load is
excessive

SOLUTION
Contact your energy supplier for help.
Near inverter, turn INVERTER AC isolator ON.
At main switchboard, turn SOLAR SUPPLY MAIN Switch ON.
At the inverter, turn the PV ARRAY DC isolator ON.
As above.
At the inverter, turn the PV ARRAY DC isolator ON.
Wait for daytime weather to improve.
Observe your panels throughout the day, and at different times of
the year to see if shading is occurring. Over time, your panels may
become partly shaded due to nearby trees or buildings.
Arrange for your PV Panels to be inspected and cleaned
On the Redback portal charts,
check Inverter-Temperature.
Is there 200mm clear space on
all sides of the inverter?
Are the cooling fins at the back
of the unit obstructed by dust,
insects, or other debris?
Wait for the temperature to
drop.
Is the inverter affected by
nearby A/C outdoor units or
other heat sources?
Is the inverter in a closed room
or shed?
Is the inverter in a full sun
location, or are there other heat
sources e.g., reflected heat, or
mounted on a metal wall?
Shutdown inverter as described in section 9.1.
Wait 10 minutes then restart the inverter as in section 9.2
Contact your installer if inverter still does not operate correctly.
Contact your installer.
Contact your installer.
Output is reduced if internal
temperature exceeds 45
Follow the suggestions below.
Ensure 200mm on all sides of
the inverter is free of
obstructions.
Clean the fins using a suitable
brush e.g., a Bottle Brush.
If in full or part sun, shading the
inverter may help. Contact your
installer for advice.
Contact your installer to discuss
options.
Ventilate or cool the room to
reduce ambient temperature.
Reduce the external heat load.
Contact your installer to discuss
options
