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. 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
57.) 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. If the unit never originally connected,
check the
Warning
menu (using the Inverter soft key from the
Home screen). Confirm source voltage and frequency.
AC source meets requirements
but is “noisy” or irregular.
MATE3 system display only:
The
Generator
input mode can accept
irregular AC power. Select that mode for that input.
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. (If this setting
was intentional, then no action is required.)
Grid use function has
disconnected from AC.
MATE3 system display only:
If activated prematurely, check the
MATE3’s
Grid Use Time
settings and the MATE3 clock settings. (If
this setting was intentional, then no action is required.)
High Battery Transfer
(
HBX
) mode has disconnected
from AC.
MATE3 system display only:
Check the
AC INPUT
hot key screen
to see if
HBX
mode is in use. If activated prematurely, check the
settings of
HBX
mode. (If this setting was intentional, then no
action is required.)
Load Grid Transfer
mode has
disconnected from AC.
MATE3 system display only:
Check the
AC INPUT
hot key screen
to see if
Load Grid Transfer
mode is in use. If activated
prematurely, check the settings of
Load Grid Transfer
mode. (If
this setting was intentional, then no action is required.)
Mini Grid
input mode has
disconnected from AC.
MATE3 system display only:
Check the
Inverter
part of the
Settings
menu to see if
Mini Grid
mode is in use. If activated prematurely,
check the settings of
Mini Grid
mode. (If this setting was
intentional, then no action is required.)
Conflicting programming.
MATE3 system display only:
Check to see if more than one of these
is enabled:
Mini Grid
,
HBX
,
Grid Use Time
,
Load Grid Transfer
.
These have conflicting priorities. Only one can be used at a time.
Grid Tied
mode has
disconnected from AC.
AC source does not meet requirements; see related entry under
“Will not sell power to the utility grid” (next page).
