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.
NOTE: The phrase “MATE system display only” also includes the MATE2 system display. This item is
intended to differentiate it from the MATE3, which has different content.
Table 4 Basic Troubleshooting Steps
Symptom Unusual LEDs Possible Cause Possible Remedy
No LEDs.
All LEDs off, 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).
Inverter LED off Jumper JP1 missing. See the Installation Manual for the location
of JP1. Confirm the jumper is present. If
missing, replace the jumper. Or follow the
Installation Manual instructions to install an
external switch.
Inverter LED off Unit defaulted off
(No system display 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.”
Inverter LED off Inverter set to OFF.
MATE system display only: Set to ON with the
INV hot key.
MATE3 system display only: Set to ON with
the
INVERTER hot key.
No AC output
(will not invert).
Inverter LED flashes Inverter set to Search or SRCH
(Search mode). MATE system display only: If constant power
is required, set to ON with the INV hot key.
MATE3 system display only: Set to ON with
the
INVERTER hot key. (If this setting was
intentional, then no action is required.)
