TROUBLE INDICATION POSSIBLE CAUSE POSSIBLE SOLUTION
OVERLOAD – GREEN (LED):
• Comes on after the inverter was
running loads.
• Comes on with the inverter off.
• Comes on after flickering 5-10
seconds of loud humming when
the AC source is connected to
the inverter.
• Comes on and inverter clicks on
and off every 40 seconds.
• Comes on while charging.
Excessive load on the AC output.
Indicates that an AC source was
wired directly to the AC output.
Indicates that the AC source was
connected to the inverter AC output.
Indicates that the AC output of
inverter is wired back to its own AC
input.
Charger circuit may be damaged.
Remove excessive AC loads and
restart the inverter.
Check for proper AC input and output
wiring.
Check for proper AC input and output
wiring.
Check for proper AC input and output
wiring (Output of inverter wired back
to its own input).
Have the inverter serviced.
INVERTER MODE (LED):
• Is on and no power output.
• Is flashing and no power output.
If good AC voltage on inverter AC
terminal block.
No AC voltage on inverter AC
terminal block.
Load is too small for search mode
circuit to detect.
Check for open AC output breakers
or fuses and AC wiring connections.
Have inverter unit serviced.
Reduce search mode watts setting;
increase AC load or defeat search
mode setting.
No power output and no warning
LED’s are on.
Battery voltage at the inverter
terminals is too high or too low.
Check battery voltage and cable
connections.
Power output is low and inverter
turns loads on and off.
Low battery. Check batteries and recharge or
replace.
Power output is low.
Loose or corroded battery and/or AC
output connections.
Check and clean all connections.
Surge power is low.
Weak batteries, battery cables too
small or too long.
Recharge or replace batteries.
Replace battery cables.
AC output voltage is low. Meter
displays 80-100 VAC with no load
running.
Measuring AC output with the wrong
type of voltmeter.
AC voltage on the output measured
with a True RMS meter is low.
Must use a TRUE RMS reading
meter (most meters are average
reading, not True RMS
reading).
Have inverter unit serviced.
CHARGER LED:
• Indicates charging, but no
charge is occurring to the
batteries.
• Is on, but no output power.
Circuit breaker on side of inverter is
open.
No AC voltage on inverter AC
terminal block.
Good AC voltage on inverter AC
terminal block.
Engage ‘AC INPUT’ circuit breaker on
side of inverter.
Check ‘AC PASS-THRU’ circuit
breaker on side on inverter.
Check for open AC output breakers
and AC wiring connections.
Charger is inoperative or giving a
low charge rate.
AC voltage has dropped out of
tolerance.
Charge control improperly set.
AC current output too small to handle
the load.
Loose or corroded battery cables.
Loose AC output connections.
Check AC voltage for proper voltage
and frequency.
Adjust charge rate.
Reduce charge amps setting or
reduce pass through loads.
Check and clean all battery
connections.
Check all AC wiring connections.
