POSSIBLE CAUSE(S)
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
output will be switched off.
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
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 con-
tinuous / 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 mod-
els have built in Ground fault Protection
Circuit).
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
mechanically 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.
SUGGESTED REMEDIES
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
1. Check DC side wire connections and fuses
or contact Technical Support
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
overload, 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
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.
