no Ac oUtPUt
On the Inverter
• Green LED on front panel is ON
• Yellow LED on front panel of the
inverter for “Input fault” is oN
• Red LED is OFF
• There is no buzzer alarm
On Remote Control SSW-R1-12B
(For SSW-1000-1500-2000-12A)
• DC input voltage is being displayed
• Power Bar Graph is OFF
• Message “Input Fault” is flashing
over temperature Shutdown
In case the fan fails or if the cooling is inad-
equate due to higher ambient temperature
or restricted airflow, the temperature inside
the inverter will start rising. Temperature rise
is sensed at one of the DC side Mosfets. If this
temperature exceeds 90C to 100C, the AC out-
put will be switched off. 1. The inverter will remain latched in this shut
down condition and will be required to be
reset manually by switching off, waiting for
15 minutes and switching oN again.
2. before using the inverter again, please ensure
that the cause of over temperature has been
removed
no Ac oUtPUt
On the Inverter
• Green LED, Yellow LED & Red LED on
front panel are off
• There is no buzzer alarm
On Remote Control SSW-R1-12B
(For SSW-1000-1500-2000-12A)
remote Control display is off and
cannot be switched oN
no activity due to loss of Dc input power to
the inverter
1. If there is no voltage at the DC input
terminals:
• Battery is dead
• External DC input fuse is blown
• Loose connection along the circuit from
the battery to the DC input terminals
2. If there is voltage at the DC input terminals:
• Internal DC input fuses have blown
1. Check DC side wire connections and fuses or
contact Technical Support
no Ac oUtPUt
On the Inverter
• Green LED is OFF in SSW-350 and 600
• Green LED is ON in SSW-1000, 1500
and 2000
• Red LED on the front panel is ON
• Yellow LED on the front panel is OFF
• There is no buzzer alarm
On Remote Control SSW-R1-12B
(For SSW-1000-1500-2000-12A)
• DC input voltage is being displayed
• Power Bar Graph is OFF
• Message “Output Fault” is flashing
Shut down due to overload or short circuit or
ground fault / leakage
1. Inverter has shut down because the power
drawn by the load is more than the continu-
ous / surge ratings or there is a short circuit on
the load side.
2. In Models SSW-350-12A and SSW-600-12A,
this shut down could also be due to ground
fault / leakage on the load side (These models
have built in Ground fault Protection Circuit).
1. reduce the load or disconnect the load that is
causing overloading.
2. Check for shorting and remove the short. In
case of SSW-350 / SSW-600, also check for
Ground fault on the load side
3. When the inverter shuts down due to over-
load, it will be latched in shutdown condition
and will require a manual reset at the inverter
by switching off and then switching oN.
Switch off the inverter. Wait for 3 min for the
internal latching circuit to de-energize and
then switch oN again after removing the
cause of overload / short circuit
4. note: SSW-1000-12A, SSW-1500-12A and
SSW-200-12A cannot be reset by using the oN
/ off push button on the remote. Manual
reset, as explained above, has to be carried
out with the help of the oN / off switch on
the inverter
no Ac oUtPUt
(For SSW-1000-1500-2000-12A)
On the NEMA5-20R Duplex GFCI outlet
• The small Green LED light on the GFCI
outlet is off
• The “Reset Button” has popped out
On the Inverter
• Green LED on the front panel of the
inverter is oN
• Yellow LED and Red LED
on the front panel of the inverter are off
• There is no buzzer alarm
On the Remote Control SSW-R1-12B
• Power Bar Graph is OFF
• Backlight is dimmed
• DC input voltage is being displayed
GFcI has tripped due to ground fault / leakage
on the load side
1. Due to ground fault / leakage on the Load
Side of the GfCI, the Load Side has been me-
chanically disconnected from its AC input side
by the relay inside the GfCI.
2. Internally, the inverter will still be working
normally and the rated AC output voltage
will be available on the internal Line Side of
the GfCI but not on the external Load Side of
the GfCI due to tripped relay in the GfCI.
Use the “reset” button on the GfCI outlet to
reset the mechanical switch to the oN position
after removing the cause of the ground fault /
leakage.
