Troubleshooting
Basic Troubleshooting
This list is organized in order of common symptoms, with a series of possible causes. Each possible
cause also has inverter LEDs which may be unusual for that mode of operation. (LEDs which are
normal, and LEDs on the system display, are not shown.) Each possible cause also shows possible
troubleshooting remedies, including system display checks where appropriate.
Table 4 Basic Troubleshooting Steps
Symptom Unusual LEDs Possible Cause Possible Remedy
No LEDs.
No LEDs, including
battery LEDs No DC voltage. Use a DC voltmeter to check the voltage
directly on the DC terminals. If not
present, the problem is external. If
present, the inverter could be damaged.
Contact OutBack Technical Support (see
inside front cover of this manual).
No Inverter LED Jumper JP1 missing. See Installation Manual for location of
JP1. Confirm the jumper is present. If
missing, replace the jumper. Or follow
Installation Manual instructions to install
an external switch.
No Inverter LED Unit defaulted off
(No MATE present; initial install; JP1
confirmed present). The inverter may have been given an
OFF command in the factory. With DC
present, use narrow pliers to remove
jumper JP1 from its pins. Once
removed, install it again. This is the
equivalent of “jiggling the switch.”
No Inverter LED Inverter set to OFF
MATE system display only: Set to ON with
INV hot key.
No AC output
(will not invert).
Inverter LED flashes Inverter set to SRCH (Search mode). MATE system display only: If constant
power is required, set to ON with INV
hot key. (If this setting was intentional,
then no action is required.)
Inverting LED not
illuminated on
questionable unit Unit is slave and is in Power Save
mode. MATE system display only: Check Power
Save levels in ADV/FX/STACK menu and
test with loads. Note if inverter comes
on at the appropriate levels. (If this
setting was intentional, then no action is
required.)
One or more
inverters will
not invert while
others do (in
multi-inverter
system).
Inverting LED flashes on
questionable unit
(Classic Series stacking
only) Unit is in Search mode. Classic Series units are mostly
independent. One unit can be in Search
mode while the other is on.
MATE system display only: Check both
ports in the status/fx/mode menu and
set both units to on. (If this setting was
intentional, then no action is required.)
