Table 4 Basic Troubleshooting Steps
Possible Cause
Erratic AC source voltage.
Inverter was set to SRCH (Search
mode).
Loads sensitive to inverter's minimal
transfer time.
Loads too large.
Undersized battery cables.
AUX output is not connected, or is
not delivering 12-volt output.
Troubleshooting
Possible Remedy
Check AC voltage on inverter's input
terminals. If not consistent, problem is
external.
MATE system display only: AC source
voltage may have dipped or hovered at
a low enough point to crash a sensitive
load before the inverter could take over.
This can happen if ac1/grid lower limit
or ac2/gen lower limit were turned
down to accommodate a problematic
AC source. To make the inverter
respond sooner, raise the lower limit
setting. (If this setting was intentional,
then no action required.)
Unit will take a moment to come out of
Search mode after transferring.
MATE system display only: If constant
power is required, set to ON with INV
hot key. (If this setting was intentional,
then no action required.)
This product is not an uninterruptible
power supply. Certain loads (such as
highly sensitive computers) may not
respond well to the inverter's 12ms
transfer time. It may be necessary to put
a true UPS on the inverter's output.
Unit can transfer more power than it can
invert. If loads are oversized, unit will
falter or crash when switching to
batteries. Reduce the size of the loads.
Battery cables that are smaller than
recommended will cause a significant
voltage drop when switching to
batteries, acting like either an overload
or a low-battery condition. Size all
cables correctly.
Test the generator or device to confirm
functionality
Test the AUX+ and AUX– terminals with
a DC voltmeter. If voltage is present
with the AUX LED on, then there is an
external connection problem. If voltage
is not present with the AUX LED on, the
AUX circuit may be damaged. Contact
OutBack Technical Support (see inside
front cover of this manual).
