REMEDY
1 Check that the voltage at the DC
input terminals is less than 16.5V for
12V model or 33V for 24V version
2 Ensure that the maximum charging
voltage of the battery charger / alterna-
tor/ solar charge controller is below 16.5V
for 12V model or 33V for 24Vversion.
3 Ensure that an un-regulated solar
panel is not used to charge a battery.
Under cold ambient temperatures, the
output of the solar panel may exceed
18V for a 12V battery system or 36V
for a 24V battery system. Ensure that
a charge controller is used between
the solar panel and the battery
1Reduce the load
2 The load is not suitable as it requires
higher power to operate. Use an inver-
ter with higher power rating.
3 If the unit goes into permanent
overload again after resseting and
removing the load completely, the unit
has become defective.
Call Technical support.
1 Check for ground fault in the load
circuit. (A ground fault will cause a
minor shock on touching)
Note: In both the cases, the unit wil
be latched in this shut-down condition.
To reset, switch the power on / off
switch to off and then on again.
Before switching on again, remove
the cause of the shut down.
1 Check that the fans are working.
If not, the fan/fan control circuit may
be defective. Call Technical support.
2 If the fans are working, check that
the ventilation slots on the suction
side and the openings on the discharge
side of the fan are not obstructed.
3 If the fans are working and the
openings are not obstructed, check
that enough cool replacement air is
available. Also check that the ambient
air temperature is less than 40ºC
4 Reduce the load to reduce the
heating effect
5 After the cause of over heating is
removed and the unit cools down,
it will reset automatically
SYMPTOM
There is no AC output.
The green LED is off
Buzzer is on.
The AC output shuts
down completely. The
red overload LED is lighted.
The green LED is off
Buzzer alarm is sounded.
Red Over Temp LED is on.
There is no AC output
POSSIBLE CAUSE
Shut-down due to high
input DC voltage
(>16.5V for 12V version
or > 33V for 24V version).
Permanent shut-down of the
AC output due to continuous
overload beyond the
continuous power rating of
the inverter.
Permanent shut-down of the
AC output by the GFCI due
to leakage > 5mA as a
result of ground fault
Shut-down due to over
temperature because of fan
failure or inadequate
cooling as a resilt of high
ambient temperature of
insufficient air exchange
