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. 

 

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.)
