Troubleshooting
TROUBLE
Reason
Solution
Low or No
Output
Voltage
Using incorrect type of voltmeter to test
output voltage.
Use true RMS reading meter.
Poor contact with battery terminals.
Clean terminals thoroughly.
Inverter
Shutdown
Battery Voltage Low
Charge Batteries
Over Load – appliances power draw
exceeds the capacity of the inverter or
the outlets
Disconnect the Load – Use a
bigger inverter. Try connecting to
the hard-wire terminal block (if
available).
Over Temperature – Thermal Shut
Down
Allow the Inverter to Cool Down.
Check the ventilation around the
inverter to make sure free air flow
around the inverter.
Low Voltage
Alarm
Sounding
The battery voltage is at a critically low
level causing the alarm to sound
Charge the batteries above the
alarm protection level. Check the
connections of the batteries and
inverter terminals.
Optional
Remote
System Not
Operating
The rocker switch of the inverter is in
the ON position.
Turn the rocker switch of inverter to
the OFF position.
The connection to the REMOTE port of
the inverter is not proper.
Ensure proper connection to both
the REMOTE port and the receiver
(in case of wireless remote system)
or switch (in case of wired remote
system).
Reverse
Polarity
In case the polarity is reversed
(connecting the + and – in reverse), the
internal spade fuses of the inverters
will blow out as a measure of
protection. This will render the inverter
inoperable.
Disconnect unit from batteries.
Disconnect all Loads. Wait 3
minutes. Open the unit and check
and replace all spade fuses.
Fan Turns On
and Off
The fan is thermostatically controller.
This is a normal condition of the unit.
Make sure there is sufficient
ventilation space behind the
inverter.
Fan is Noisy
Debris may be caught in fan
Disconnect unit from batteries.
Disconnect all Loads. Wait 3
minutes. Check and remove any
debris from the fan system. Use a
vacuum cleaner to clean dust and
debris from the fan inlet.
