Shut-down due to high
input DC voltage –
> 16.5V for 12V versions
and > 33V for 24V
versions.
Permanent shut-down of
the AC output due to con-
tinuous overload beyond
the continuous power
rating of the inverter.
Shut-down due to over
temperature because of
fan failure or inadequate
cooling as a result of high
ambient temperature or
insufficient air exchange
GfCI has tripped due to
leakaage or due to Neutral
to Ground bond on the
load side.
ReMeDY
Check that the voltage at the DC input termi-
nals is less than 16.5V for 12V versions and less
than 33V for 24V versions.
Ensure that the maximum charging voltage of
the battery charger / alternator / solar charge
controller is below 16.5V for 12V versions and
below 33V for 24V versions.
Ensure that an unregulated solar panel is not
used to charge a battery. Under cold ambient
temperatures, the output of the solar panel
may exceed 22V for 12V system or 42V for
24 V system. Ensure that a charge controller is
used between the solar panel and the battery.
Reduce the load.
The load is not suitable as it requires higher
power to operate. Use an inverter with higher
power rating.
If the unit goes into permanent overload again
after resetting and removing the load com-
pletely, the unit has become defective.
Call Technical support.
note: The unit will be latched in this shut-
down condition and will require manual reset.
To reset, switch Off the power
ON/Off switch, wait for 3 minutes and then
switch ON again.
Before switching on again, remove the cause
of the shut-down.
Check that the fan is working. If not, the fan
control circuit may be defective. Call
Technical Support.
If the fan is working, check that the ventilation
slots on the suction side and the openings
on the discharge side of the fan are not
obstructed.
If the fan is working and the openings are not
obstructed, check that enough cool replace-
ment air is available. Also check that the ambi-
ent air temperature is less than 40ºC.
Reduce the load to reduce the heating effect.
After the cause of overheating is removed and
the unit cools down sufficiently, it will reset
automatically.
Check load side circuits for leakage or Neutral
to Ground bonding and correct. Press "Reset
Button" on the GfCI to reset. Ensure that the
inverter is ON before re-setting.
