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.
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 45.) If not present, the problem is external. If present,
the inverter could be damaged.
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.
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 it never originally connected,
check the
Warning
menu (using the
<Inverter>
soft key
from the Home screen). Confirm source voltage / frequency.
AC source meets
requirements but is “noisy” or
irregular.
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.
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.
System display only:
If activated prematurely, check the
Grid
Use Time
settings and the system display clock. (If this
setting was intentional, then no action is required.)
High Battery Transfer
(
HBX
) mode has
disconnected from AC.
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.
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.
System display only:
Check to see if more than one of these
is enabled:
Mini Grid
,
HBX
,
Grid Use Time
,
Load Grid
Transfer
. Due to conflicting priorities, only one can be used.
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).
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).
Will not charge.
No AC input.
See “Will not connect to AC” category.
Charger set to
Off
.
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.)
GridZero
mode in use.
System display only:
The charger is inoperative in
GridZero
.
(If this setting was intentional, then no action is required.)
