TECHNICAL INFORMATION
TROUBLESHOOTING GUIDE
INVERTER - If ERROR LED comes on, see ERROR CAUSES section
PROBLEM
Unit will not come on
(no LED's are on) and the
Control Panel Display is blank or off
Unit comes on, but goes off quickly
(several attempts made)
No AC power output
INVERTING LED is on, with no ERROR
LED.
Look at Control Panel display under
'Inverter volts' and check AC voltage on
inverter AC terminal block.
AC1/AC2 IN GOOD LED is flashing
(with no AC connected to the input).
No AC power output
INVERT LED is flashing.
Low AC power output or
Low surge power
INVERT LED is on
(AC inductive loads are not running at
full speed).

INDICATION
DC voltage on the inverter's DC
terminals is incorrect.
DC voltage on the inverter's DC
terminals is correct
Excessive load on output, unit is in over-temperature protection (needs to cool
down), incorrect battery voltage.
See ERROR CAUSES section
Correct AC voltage on Control Panel display but no AC voltage on inverter AC
terminal block.
Check for open circuit breaker on the inverter. If circuit breaker on the inverter is not
open (popped), have the inverter serviced.
Correct AC voltage on Control Panel display and on inverter AC terminal block.
Check for open AC output breakers or fuses and bad output wire connections
AC voltage on Control Panel display or inverter AC terminal block is incorrect: have
unit serviced
AC load too small for Search mode
circuit to detect
Insufficient DC current being provided
to the inverter to operate the AC loads

SOLUTION
Check the battery voltage, fuses or
breakers and DC cable connections to
the inverter
Have unit serviced
Have unit serviced
Reduce search watts setting, increase
load above search watts setting, or defeat
search mode by selecting ON.
Check the battery voltage, fuses or
breakers and cable connections.
Ensure the battery bank is sufficient
(check for low DC voltage while running
the load).
Ensure the cable length and size is
correct (see owner's manual for correct
cable). Tie the battery cables together to
reduce inductance.
