Symptom Possible Cause Possible Remedy
Inverter set to Search (Search
mode).
MATE3 system display only: If constant power is required, set to On
with the INVERTER hot key. (If this setting was intentional, then
no action is required.)
One or more units
have no output but
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 49.) If not present, the problem is external. If present, the
inverter could be damaged. Contact OutBack Technical Support. 4
The L1 output is wired to its L2
input, or the other way around.
The problem is accompanied by
shifts in frequency.
Disconnect the wires from the inverter’s AC input terminals or AC
output terminals, or both. If the problem immediately disappears,
it is an external wiring issue. The inverter’s input and output
terminals must remain isolated from each other.
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.)
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).
