Symptom Possible Cause Possible Remedy
Inverter clicks
repeatedly. AC
output voltage rises
or drops to unusual
levels with every
click.
Inverter’s output has been
connected to its input. Voltage
shifts are the result of trying to
match its own voltage.
Disconnect the wires from the inverter’s AC input or AC output
terminals, or both. If the problem immediately disappears, it is an
external wiring issue. The inverter’s
AC HOT IN
and
AC HOT OUT
must remain isolated from each other.
Low AC input voltage. Can be
caused by weak AC source, or
by faulty input connection.
Test
AC HOT IN
and
AC NEUTRAL IN
terminals with an AC
voltmeter. (See page 57.) If low or fluctuating, this is an external
problem.
A generator is connected to the
input terminals while the unit is
in the
Grid Tied
input mode.
The inverter is not intended to sell power to a generator. The
selling activity will drive the generator voltage up to the
disconnection point. It will then reconnect to the generator and
try again. Change input modes, or move the generator to an
input with a different mode selected.
Inverter hums loudly.
System display may
show messages for
high battery voltage,
low battery voltage,
or backfeed error.
Inverter output is being
supplied with an external AC
source that is out of phase.
Disconnect
AC HOT OUT
and
AC NEUTRAL OUT
wires. Turn the
inverter off and then on. If the problem clears, reconnect the AC
output wires. If the problem recurs when reconnected, an
external AC source is connected to the output.
Inverter has been incorrectly
stacked with another unit on
the same output. All units
come defaulted as master.
Check HUB10.3 ports and make certain the master inverter is
plugged into port 1.
MATE3 system display only: Check stacking settings in the
Inverter
Stacking
menu. Only one master is allowed per system.
Generator, external
fan, etc. fails to start
when signal is
provided by AUX
output.
AUX output is not connected. Test the generator or device to confirm functionality. Test the
AUX terminals with a DVM. If 12 Vdc is present when the menu
indicates the function is
On
(and the device still does not work),
then there is an external connection problem. If 12 Vdc is not
present with the function
On
, the AUX circuit may be damaged.
Contact OutBack Technical Support.

Advanced Generator
Start (
AGS
) fails to
activate when
conditions are met
(or starts when
conditions are
not met).
MATE3 system display is not
present.
G
programming is located in the MATE3 and cannot function if
the MATE3 is removed.
Other AUX functions are in
operation.
Gen Alert
or another AUX function may try to start or stop the
generator using the wrong criteria. Make sure all other AUX
functions are disabled.
