Basic Troubleshooting
Table 6 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.

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 55.
Table 6 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. 3
Jumper J3 missing. See the Installation Manual for the location of J3. Confirm the
jumper is present. If missing, replace the jumper. Or follow the
Installation Manual instructions to install an external switch.
Unit defaulted off
(No MATE3 present; initial
install; J3 confirmed present).
The Radian inverter is given an initial Off command in the factory.
With DC present, use narrow pliers to remove jumper J3 from its
pins. Once removed, install it again. This is the equivalent of
“jiggling the switch.”
Inverter set to Off. MATE3 system display only: Set to On with the INVERTER hot key.

Metal pads are located at
these locations.
In troubleshooting, AC
voltages can be measured at
this series of test points.
