Troubleshooting 
Basic Troubleshooting 
Table 7 is organized in order of common symptoms, with a series of possible causes. Each cause also 
shows possible troubleshooting remedies, including system display checks where appropriate. 
These instructions are for use by qualified personnel who meet all local and governmental code 
requirements for licensing and training for the installation of electrical power systems with AC and DC 
voltage up to 600 volts. 
Figure 19  AC Test Points 
WARNING: Shock Hazard
During an error shutdown, the inverter’s output terminals are not live. However, 
if the inverter recovers from a shutdown, the terminals will become live without 
notice. Several error shutdowns can be recovered automatically, including 
Low 
Battery V
, 
High Battery V
, and 
Over Temperature
. See page 58. 
Table 7  Troubleshooting  
Symptom  Possible Cause  Possible Remedy
No AC output 
(will not invert). 
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 the Installation Manual for the location of the jumper. Confirm

install; Inverter ON/OFF jumper 
confirmed present). 
T
he FXR inverter is given an initial Off command in the factory. 
With DC present, use narrow pliers to remove the jumper from its 
pins. Once removed, install it again. This is the equivalent of 
“jiggling the switch.”
