Symptom Possible Cause Possible Remedy
One or more
inverters will not
invert while others
do (in multi-inverter
system).
Unit is slave and is in Power
Save 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 test points. (See
page 51.) If not present, the problem is external. If present, the
inverter could be damaged. Contact OutBack Technical Support. 4
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 both
the MATE3’s
Grid Use Time settings and the MATE3 clock settings
in the System menu. (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.)
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 the
following are enabled:
Mini Grid, HBX, Grid Use Time. These have
conflicting priorities and 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).
For only the B or C inverters on
a three-phase system: Power is
unacceptable on that phase.
Check the source voltage and frequency. If the AC source voltage
or frequency cannot be maintained on the B or C phases, the
inverters on those phases will return to inverting. This ensures
that a three-phase output is maintained to the loads. If the source
becomes acceptable, the inverters will connect to it again.
Conflicting AC sources. Priority
input is interfering with
secondary input.
If AC is present on the priority input, the inverter will not connect
to AC on the second input. This is true even if the first input is not
connected for other reasons (programming, low power quality).
