TROUBLESHOOTING GUIDE
Table. INVERTER POWER SWITCH TURNED ON
TROUBLE/ INDICATION
POSSIBLE CAUSE
SUGGESTED REMEDY
No AC output:
-
Yellow LED is lit
-
Red and Green LEDs are not lit
-
No audible alarm is sounded
Inverter has overheated and
thermal shutdown has been
activated
Remove or reduce the load and wait
for the inverter to cool down.
The inverter will be latched in shut
down conditions and will require
manual reset once it has cooled down
sufficiently.
To reset, switch off, wait for 3 min. and
switch on again.
No AC output:
-
Red, Yellow & Green LEDs are not lit
-
No audible alarm
DC side wires are loose OR
external DC side fuse has opened
OR the Inverter’s internal DC side
fuses have open
Check DC side wire connection and
fuses OR contact technical support
Non-continuous AC output:
-
Red LED is lit on & off
-
Green LED is lit on & off
-
Yellow LED is not lit
-
No audible alarm
Inverter output power limited
by overload / surge circuit
protection circuit
Reduce load.
No AC output (latch up):
-
Red LED is lit
-
Yellow and Green LEDs are not lit
-
No audible alarm
Inverter has shut down due to
overload
In Models SSW-350 and SSW-600
this shut down could also be
due to ground fault on the load
side (These models have built in
Ground Fault Protection Circuit).
Reduce the load or disconnect the load
that causes overloading.
In case of SSW-350 / SSW-600, also
check for Ground fault on the load
side
When the inverter shuts down due
to overload / ground fault (in case of
SSW-350 / SSW-600), it will be latched
in the shutdown condition and will
require a manual reset. Switch off
the inverter. Wait for 3 min for the
internal latching circuit to de-energize
and then switch on again
No AC output (For SSW-1000, 1500 and 2000
with GFCI)
-
Small green LED mounted on the GFCI
outlet is not lit
-
Green LED on the inverter is lit
-
Red and Yellow LEDs are not lit
-
No audible alarm
AC output side of the GFCI
protected outlet has been
mechanically disconnected from
its AC input side due to leakage /
Ground fault on the load side (in
this case, the inverter does not
shut down and AC power is still
available on the input side of the
GFCI)
Remove the Ground faulted AC load
and mechanically reset the GFCI using
the Reset Button provided on the GFCI
