INVERTER - If ERROR LED comes on, see ERROR CAUSES section
PROBLEM
INDICATION
SOLUTION
Unit will not come on
(no LED’s are on) and the
Control Panel Display is blank or off
DC voltage on the inverter’s DC
terminals is incorrect.
Check the battery voltage, fuses or
breakers and DC cable connections to
the inverter
DC voltage on the inverter’s DC
terminals is correct
Have unit serviced
Unit comes on, but goes off quickly
(several attempts made)
Excessive load on output, unit is in over-temperature protection (needs to cool
down), incorrect battery voltage.
See ERROR CAUSES section
No AC power output
INVERTING LED is on, with no ERROR
LED.
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.
Look at Control Panel display under
‘Inverter volts’ and check AC voltage on
inverter AC terminal block.
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
AC1/AC2 IN GOOD LED is flashing
(with no AC connected to the input).
Have unit serviced
No AC power output
INVERT LED is flashing.
AC load too small for Search mode
circuit to detect
Reduce search watts setting, increase
load above search watts setting, or defeat
search mode by selecting ON.
Low AC power output or
Low surge power
INVERT LED is on
(AC inductive loads are not running at
full speed).
Insufficient DC current being provided
to the inverter to operate the AC loads
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.
