An error message is caused by a critical fault.  In most cases when this occurs, the unit will shut down 
and the inverter’s ERROR LED (see page 11) will illuminate.   See the system display manual for 
instructions on viewing errors.  One or more messages will display yes in the MATE system display;  Y 
in the MATE3.  If a message says no (or N), it is not the cause of the error.   

Error screens can only display errors; they cannot clear them.  It is possible to clear an error by 
resetting the inverter.  The inverter must be turned off, and then on, to reset it.   Other possible steps 
are shown below (although it is still necessary to reset the inverter). 

low ac 
output 
voltage  

Low Output 
Voltage 

Inverter’s AC regulation cannot be 
maintained under high load conditions. 

Check loads and measure current draw.  
Remove loads as necessary. 

stacking 
error 
detected 

 

Stacking Error 

Programming problem among stacked 
units.   (Often occurs if there is no master.)  
Can also occur when ac output backfeed 
occurs. 

Check stacking programming and designation 
of master.  (See page 25.) 

Check for output backfeed from external 
source.  Disconnect output if necessary. 

Over 
Temperature 

Inverter has exceeded its maximum 
allowed operating temperature.   

Shut off the inverter to reduce the 
temperature, or add external cooling.   

 

 

Low Battery V 

DC voltage is below Low Battery Cut-Out 
(LBCO) set point.   

This error can be triggered by other 
causes.  It can appear along with low ac 
output voltage, ac output shorted, or ac 
output backfeed errors. 

If this error accompanies other errors, treat 
those conditions as appropriate. 

If it occurs by itself:  Recharge the batteries.  
The error will clear automatically if an external 
AC source is connected and the inverter’s 
charger comes on. 

phase loss 
error  

Phase Loss 

A slave was ordered to transfer to AC by 
the master, but no AC is present.  The unit 
continues inverting.  This is the only 
“Error” that is not accompanied by a 
shutdown. 

Check the AC voltage on the inverter input 
terminals.  If AC voltage is not present, 
problem is external.  If AC voltage is present, 
the unit may be damaged.  Contact OutBack 
Technical Support (see inside front cover of 
this manual). 

high battery 
voltage  

 

High Battery V  DC voltage exceeded acceptable level 

(specified on page 13). 

Check the charging source.  This problem is 
usually the result of external charging.  This 
error will clear automatically if conditions 
are removed. 

 

 

 

 

Inverter exceeded its maximum surge 
current due to severe overload. 

Check the loads and wiring.  This issue is 
usually the result of a wiring problem (a short), 
as opposed to a poorly-sized load. 

 

 

 

 

Usually indicates another AC power 
source (out of phase with the inverter) 
was connected to the unit’s AC output. 

Disconnect the AC OUT wires from the 
inverter.  Check the wires (not the inverter) 
with an AC voltmeter.  If an AC source is 
present, shut it off.
