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.
Symptom Unusual LEDs
No LEDs, including
battery LEDs
No LEDs.
No Inverter LED
No Inverter LED
No AC output
(will not invert).
No Inverter LED
Inverter LED flashes
One or more Inverting LED not
inverters will illuminated on
not invert while questionable unit

Table 4 Basic Troubleshooting Steps

Possible Cause
No DC voltage.
Jumper JP1 missing.
Unit defaulted off
(No MATE present; initial install; JP1
confirmed present).
Inverter set to OFF
Inverter set to SRCH (Search mode).
Unit is slave and is in Power Save
mode.

Troubleshooting

Possible Remedy
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).
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.
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."
MATE system display only: Set to ON with
INV hot key.
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.)
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.)
