Trouble-shooting
Following diagnosis of the fault deals with general causes and is valid for most applications. For all faults the
handbook of the inverters should be consulted in the first place.
FAILURE INDICATION POSSIBLE CAUSE
SOLUTION
Inv erter will not switch ov er to
generator or mains operation
Circuit breaker or fuse in the AC-in
input is open as a result of overload
Remove overload or short circuit on AC-out-1
or ACout-2, and reset fuse/breaker
Inv erter operation not initiated
when switched on
The battery voltage is excessively
high or too low. No voltage on DC
connection
Ensure that the battery voltage is within the
correct range
“Low battery ” LED f lashes
The battery voltage is low
Charge the battery or check the battery
connections
“Low battery ” LED lights
The converter switches off because
the battery voltage is too low
Charge the battery or check the battery
connections
“Ov erload” LED f lashes
The converter load is higher than the
nominal load
Reduce the load
“Ov erload” LED lights
The converter is switched off due to
excessively high load
Reduce the load
“Temperature” LED f lashes or
lights
The environmental temperature is
high, or the load is too high
Install the converter in cool and well-ventilated
environment, or reduce the load
“Low battery ” and “ov erload” LEDs
f lash intermittently
Low battery voltage and excessively
high load
Charge the batteries, disconnect or reduce the
load, or install higher capacity batteries. Fit
shorter and/or thicker battery cables
“Low battery ” and “ov erload” LEDs
f lash simultaneously
Ripple voltage on the DC connection
exceeds 1,5Vrms
Check the battery cables and battery
connections. Check whether battery capacity
is sufficiently high, and increase this if
necessary
“Low battery ” and “ov erload” LEDs
light
The inverter is switched off due to an
excessively high ripple voltage on
the input
Install batteries with a larger capacity. Fit
shorter and/or thicker battery cables, and
reset the inverter (switch off, and then on
again)
One alarm LED lights and the
second f lashes
The inverter is switched off due to
alarm activation by the lighted LED.
The flashing LED indicates that the
inverter was about to switch off due
to the related alarm
Check this table for appropriate measures in
regard to this alarm state
The charger does not operate
·
The AC input voltage or frequency
is not within the range set
·
Ensure that the AC input is between 185
VAC and 265 VAC, and that the frequency
is within the range set (default setting 45-
65Hz)
·
Circuit breaker or fuse in the AC-in
input is open as a result of
overload
·
Remove overload or short circuit on AC-out-1
or ACout-2, and reset fuse/breaker
·
The battery fuse has blown
·
Replace the battery fuse
·
The distortion or the AC input
voltage is too large (generally
generator supply)
·
Turn the settings WeakAC and dynamic
current limiter on
The charger does not operate.
“Bulk” LED f lashes and “Mains on”

MultiPlus is in “Bulk protection”
mode thus, the maximum bulk
