Troubleshooting
Symptom
Possible Cause
Possible Remedy
One or more units
have no output but
others do (in multi-
inverter system).
Unit is slave and is in Silent
mode.
MATE3 system display only:
Check Power Save levels in the
Inverter Stacking
menu and test with loads.
MATE/MATE2 system display only:
Check Power Save levels in the
ADV/FX/STACK
menu and test with loads.
Determine if the inverter comes on at the appropriate levels.
If this setting was intentional, then no action is required.
Will not connect to
the AC source.
No AC input.
Check the AC voltage on the inverter’s input terminals. (See page
37.) If not present, the problem is external. If present, the inverter
could be damaged. Contact OutBack Technical Support.

AC source does not meet
requirements.
MATE3 system display only:
Check the
Last AC Disconnect
screen
(using the
AC INPUT
hot key and the
Discon
selection) for the
reason for disconnection.
MATE/MATE2 system display only:
Check
STATUS/FX/DISCON
for
the reason for disconnection.
If the unit never originally connected, check the
Warning
menu.
Confirm source voltage and frequency.
Inverter was manually set to
disconnect from AC.
MATE3 system display only:
Change the AC Input Control setting
from
Drop
to
Use
with the
AC INPUT
hot key.
MATE/MATE2 system display only:
Change the AC Input Control
setting from
Drop
to
Use
with the
AC IN
hot key.
If this setting was intentional, then no action is required.
Grid use function has
disconnected from AC.
MATE, MATE2 or MATE3 system display only:
If activated
prematurely, check the system display’s
Grid Use Time
settings
and the clock settings.
HBX
or another grid use function may also be active. If more than
one function is active, the programming may conflict.
Low charge rate.
Charge complete or nearly
complete.
Check the DC voltage and charging stage using the system
display, if present. Confirm with DC voltmeter.
System display DC meter reads
significantly higher than actual
battery voltage.
Check the DC voltage on the inverter’s DC terminals. If different
from the system display reading, the inverter could be damaged.
Otherwise check the DC voltage on the batteries with a voltmeter.
If different from the reading on the inverter, this could be a DC
connection problem.
High output loads.
If total loads and charge exceed the AC input setting, charge rate
decreases to give priority to the loads. Turn off some of the
output loads and test the charge rate again.
High temperature.
The inverter will reduce the current rate for charging and other
activities if the internal temperature exceeds a certain level.
Check temperature readings and allow the inverter to cool if
necessary. (See page 42.) External cooling may also be applied.
Will not charge.
No AC input.
See “Will not connect to AC” category.
Charger set to
Off
.
MATE3 system display only:
Check the
Charger Mode
screen with
the
CHARGER
hot key and set to
On
or
Auto
. (If this setting was
intentional, then no action is required.)
MATE /MATE2 system display only:
Check the
Charger Control
screen with the
AC IN
hot key and set to
ON
or
AUTO
.
If this setting was intentional, then no action is required.
